The first author, Manuela Isacson called all labor departments in Sweden twice, and asked the 95 midwives about their cord clamping practice.

Now we publish the results:

INTRODUCTION The timing of cord clamping impacts children’s short- and long- term well-being. When making clinical decisions, midwives incorporate their tacit and professional knowledge, experience and current evidence. There appears to be a lack of knowledge regarding Swedish midwives’ management of the third stage of labor and cord clamping practice. The aim of this study was to explore Swedish midwives’ clinical practice concerning umbilical cord clamping and the third stage of labor in spontaneous vaginal births.
METHODS The study was designed as a cross-sectional telephone survey including 13 questions. Midwives were randomly selected from 48 births units in Sweden. Two midwives from each unit were interviewed. The primary outcome was timing of umbilical cord clamping practice in full-term infants. Secondary outcomes were the management of the third stage of labor including prophylactic use of synthetic oxytocin, the timing of cord clamping in preterm infants, controlled cord traction, uterine massage, and cord milking.
RESULTS Altogether, 95 midwives were interviewed. In full-term infants, all midwives preferred late cord clamping. Considerable heterogeneity was seen regarding the practices of synthetic oxytocin administration postpartum, controlled cord traction, uterine massage or cord milking, and cord clamping in preterm infants.
CONCLUSIONS Midwives in Sweden modify recommendations regarding delayed cord clamping in a way they might perceive as more natural and practical in their daily, clinical work. The study revealed a reluctance toward the administration of prophylactic oxytocin due to fear that the drug could pass to the infant. An overall large variation of the management of the third stage of labor was seen.

Two of the persons involved in the development of Lifestart trolley (http://www.inditherm.com/medical/neonatal-resuscitation-lifestart/) has published a review in Maternal Health, Neonatology and Perinatology.
"Abstract: The rationale for keeping the mother and her newborn together even when neonatal resuscitation is required is presented. The development of a customised mobile resuscitation trolley is detailed explaining how the resuscitation team can be provided with all the facilities of a standard resuscitation trolley to resuscitate the neonate at the mother’s side with an intact cord. Alternative low tech solutions which may be appropriate in low resource setting and with a low risk population are also described."

  • The Novel Use of Umbilical Cord Blood to Obtain Complete Blood Counts for Critical Neonatal Assessment

    Cureus. 2022 Aug 14;14(8):e28009. doi: 10.7759/cureus.28009. eCollection 2022 Aug.ABSTRACTBACKGROUND: Neonates undergoing clinical evaluations are often subjected to potentially painful phlebotomy for laboratory tests. The use of cord blood laboratory values for admission has been suggested as a means to decrease the risk of painful venipuncture and anemia.METHODS: Peripheral and umbilical cord blood complete blood count (CBC) results were obtained from infants who required a CBC. Results were compared using the Sysmex XN heme analyzer (Sysmex, Kobe, Japan).RESULTS: White blood cell (WBC) and hemoglobin (HgB) values were significantly higher in peripheral samples than in cord samples. The mean cord WBC count was 14.1 × 103/mm3 versus 15.6 × 103/mm3 peripherally (p < 0.001). The mean cord HgB was 15.8 g/dL versus 16.8 g/dL peripherally (p < 0.001). Cord platelet (Plt) counts were, conversely, lower in peripheral samples than in cord samples (264.8 × 103/mm3 versus 242.3 × 103/mm3, respectively; p < 0.001). Although statistically different, the mean CBC values from both samples were within the reference ranges. Delayed cord clamping (DCC) increased peripheral versus cord HgB difference nearly threefold (0.6-1.7 g/dL; p = 0.01).CONCLUSIONS: Cord blood is an acceptable source for CBC blood sampling in newborn infants and can be used for clinical decisions. CBC laboratory values for cord blood remained within the peripheral blood reference range, with slight variability between the two samples.PMID:36134078 | PMC:PMC9470209 | DOI:10.7759/cureus.28009…

  • The effect of placental transfusion on hemodynamics in premature newborns: a randomized controlled trial

    Eur J Pediatr. 2022 Sep 21. doi: 10.1007/s00431-022-04619-0. Online ahead of print.ABSTRACTDespite of growing evidence of the beneficial effects of placental transfusion techniques, there is no available sufficient data about their effects on vulnerable hemodynamics and myocardium of premature infants. The purpose of this work is to study ventricular functions and hemodynamics after applying different placental transfusion techniques, delayed cord clamping (DCC), cut cord milking (C-UCM), and intact cord milking (I-UCM). Sixty-four infants delivered whether by C-section or vaginal delivery were randomly assigned to undergo C-UCM (20-30 cm), I-UCM (3-4 strippings), and DCC (30-60 s). Functional echocardiography was done on day 1 and day 3 of life for 57 infants. Primary outcome variable was superior vena cava flow measurement in infants having placental transfusion in the first 24 h of life and between 64 and 72 h. Secondary outcomes were other echocardiographic and clinical hemodynamic parameters, and biventricular functions in those infants. Of a total 196 preterm infants ≤ 32 weeks delivered in the study period, from January 2021 to August 2021, 57 infants were eligible and survived till the second examination. They were randomly assigned to the three groups. Neonates randomly assigned to DCC had significantly higher superior vena cava flow and lower right ventricular systolic function in the first 24 h of life. This finding vanished at day 3. Neonates undergone different methods of placental transfusions had similar hemoglobin, admission temperature, and mean blood pressure in the first 24 h of life.CONCLUSION: Despite their potential benefits, placental transfusions have shown to alter the hemodynamics and adversely affect myocardial function of premature neonates.TRIAL REGISTRATION: This trial was registered in the clinical trial gov NCT04811872.WHAT IS KNOWN: • Placental transfusion techniques might have benefits regarding prematurity- related morbidities and mortality.WHAT IS NEW: • Placental transfusion might adversely affect the myocardium and alter hemodynamics in premature infants.PMID:36129535 | DOI:10.1007/s00431-022-04619-0…

  • Umbilical cord clamping time and maternal satisfaction

    Midwifery. 2022 Sep 13;115:103487. doi: 10.1016/j.midw.2022.103487. Online ahead of print.ABSTRACTOBJECTIVE: Clamping of the umbilical cord is part of the third stage of delivery. Delayed cord clamping (DCC) is recommended due to its contribution to prevention of anaemia. There is no evidence on the effect of DCC on maternal satisfaction. The aim of this study is to evaluate the effect of different sociodemographic and obstetric factors, including the timing of cord clamping, on maternal satisfaction with the birth experience in our healthcare system.DESIGN: Pragmatic non-drug intervention study with simple random assignment of participating mothers (Clinical Trials N°: NCT03624335).SETTING: A public, university-level hospital in Villarreal city, eastern Spain.PARTICIPANTS: Childbearing woman, gestation week between 35 and 42 weeks, with regular medical pregnancy checks, single pregnancy and vaginal delivery (N = 198, 80% of the women recruited).INTERVENTIONS: umbilical cord clamping within 60 seconds of the birth (Early cord clamping, ECC) versus umbilical cord clamping after pulsation had been ceased (Delayed cord clamping, DCC).MEASUREMENTS: Birth satisfaction was measured using the Mackey Childbirth Satisfaction Rating Scale (MCSRS). Additionally, sociodemographic data, degree of knowledge about the moment of clamping and type of breastfeeding data were recorded. The Mann-Whitney and Kruskal-Wallis tests for comparison of the mean of two, three, or more groups, respectively, and Chi-square and Spearman for comparison of two qualitative and quantitative variables, respectively, were used. To determine the weight of each factor of MCSRS, an exploratory factor analysis was carried out using the maximum likelihood method for factor extraction and the varimax method for factor rotation. The adequacy of the factor analysis was checked by mean of Kaiser-Meyer-Olkin test and Bartlett sphericity test. The level of significance was set at a p-value of < 0.05.FINDINGS: The average degree of satisfaction was 4.55/5 (SD: 0.37). No statistically significant difference was observed between mothers' satisfaction according to mother level of study or mother's place of birth, while it changed significantly with age (p = 0.0398). Within the obstetric variables, satisfaction was significantly associated with spontaneous amniorrhexis, the duration of the second stage of delivery, and the Apgar value of the newborn at the first minute of life, and was independent of the number of previous pregnancies and deliveries, use of intrapartum oxytocin, epidural analgesia, episiotomy, the weight of the child at birth and type of breastfeeding. Furthermore, there was no relationship between the time of clamping and satisfaction (p = 0.5178).KEY CONCLUSIONS: Maternal satisfaction with the birth experience varies with the age of the childbearing woman, and some intrapartum factors and the result is not influenced by the time of clamping of the umbilical cord. Therefore, this component of the physiological management of childbirth provides additional benefits for the health of the neonate, without negative consequences on the final perception of the maternal health care received.IMPLICATIONS FOR PRACTICE: If there are no reasons that justify an early umbilical cord clamping, delaying it brings benefits to the neonate, without negatively affecting the maternal assessment of the experience of childbirth.PMID:36126369 | DOI:10.1016/j.midw.2022.103487…

  • The hematological impact of umbilical cord milking versus delayed cord clamping in premature neonates: a randomized controlled trial

    BMC Pregnancy Childbirth. 2022 Sep 19;22(1):714. doi: 10.1186/s12884-022-05046-7.ABSTRACTBACKGROUND: The hematological impact of umbilical cord milking (UCM) was compared to that of delayed cord clamping (DCC) as a faster placental transfusion technique for preterm neonates (between 24 and 34 + 6 weeks gestation). A comparison of important neonatal morbidities was also made.METHODS: This was an open-label randomized trial conducted from June 8, 2017, to April 22, 2019. Two hundred patients with preterm deliveries (24 and 34 + 6 weeks gestation) were assigned to the DCC or UCM group at random at a ratio of 1:1. The study power was 80% for a difference in the hematocrit value of 3% and Hb value of one gram, and an alpha error of 0.05.RESULTS: The following variables were analyzed in the comparison of UCM vs. DCC: first draw hemoglobin: 17.0 ± 1.9 vs. 16.8 ± 1.8 gm/dl (95% CI -0.75-0.29, P 0.383); first draw hematocrit: 55.6 ± 6.4 vs. 55.2 ± 6.4% (95% CI -2.18-1.38, P 0.659); peak hematocrit: 56.9 ± 6.4 vs. 56.3 ± 6.7% (95% CI -2.41-1.26, P 0.537); the need for respiratory assistance (47% vs. 30%, P 0.020), inotropes (16% vs. 6%, P 0.040), and blood transfusion (26% vs. 12%, P 0.018); and the occurrence of intraventricular hemorrhage (9% vs. 5%, P 0.407), necrotizing enterocolitis (6% vs. 2%, P 0.279), sepsis (25% vs. 15%, P 0.111), and neonatal death (13% vs. 4%, P 0.40).CONCLUSION: UCM facilitated a rapid transfer of placental blood equivalent to that of DCC for premature neonates. However, it resulted in increased rates of interventions and morbidities, especially in extremely preterm neonates.TRIAL REGISTRATION: The clinical trial was registered on May 10, 2017, with registration number (NCT03147846).PMID:36123638 | PMC:PMC9484179 | DOI:10.1186/s12884-022-05046-7…

  • Delayed cord clamping practice at birth: A narrative review of literature

    Eur J Obstet Gynecol Reprod Biol. 2022 Oct;277:116-121. doi: 10.1016/j.ejogrb.2022.08.024. Epub 2022 Sep 5.ABSTRACTBACKGROUND: Anaemia in infants is a major public health concern particularly in low and middle-income countries. Delayed cord clamping (DCC) has been advocated as a strategy to decrease iron deficiency anaemia in infants because of the benefits that come with placental transfusion. Despite the documented benefits of delayed cord clamping in preventing anaemia the current practices of delayed cord clamping by midwives and obstetricians across countries and in different contexts is unclear. This narrative review assesses the literature on delayed cord clamping practices published from 2013 to February 2022, in order to examine current practice in birth units globally, and with a focus in low and middle-income countries (LMICs).METHOD: A search of four bibliographic databases Medline, Scopus (Elsevier), ProQuest, CINAHL and two network and search engines, Wiley and Google Scholar, was undertaken from 2013 to February 2022 using key terms related to delayed cord clamping and immediate cord clamping. A snowball method as well as backward and forward reference checking was also undertaken.RESULTS: The search strategy identified 10 studies on umbilical cord clamping practices by midwives and obstetricians. Only two studies were conducted in low and middle-income countries.CONCLUSION: Despite the potential benefits of DCC in reducing anaemia, particularly in low and middle-income countries where the burden of anaemia is a public health concern, there is a paucity of literature on current DCC practices by obstetricians and midwives. Research to establish current DCC practices in these countries is needed to address this gap in the literature.PMID:36084387 | DOI:10.1016/j.ejogrb.2022.08.024…

  • Protocol for a Nested, Retrospective Study of the Australian Placental Transfusion Study Cohort

    Cureus. 2022 Aug 4;14(8):e27693. doi: 10.7759/cureus.27693. eCollection 2022 Aug.ABSTRACTBackground Neonates, particularly if born preterm or with congenital anomalies, are among the pediatric patients most likely to need blood transfusion. However, they are also particularly vulnerable to adverse consequences of blood transfusion. Aiming to clamp the umbilical cord for at least a minute after birth is a simple safe procedure that is being increasingly adopted worldwide, although may be associated with increased rates of polycythemia and jaundice. It may also reduce the proportion of preterm babies who need a blood transfusion. The mechanisms for this are not fully understood. Potential mechanisms could include an increased volume of blood transfusion from the placenta to the baby after birth, and an overall reduction in the severity of illness in the first weeks after birth, which could lead to fewer blood tests and greater tolerance of anemia, or enhanced erythropoiesis. Objectives To investigate the mechanism behind the reduced need for blood transfusions after deferral of cord clamping. Methodology This protocol outlines the methods and data analysis plan for a study using nested retrospective data from a large randomized trial combined with additional data collected from patient medical and pathology records. The additional data items to be collected all relate to the receipt of transfusion and the factors that affect the risk for transfusion in preterm babies. The analysis will include all randomized babies from Australia and New Zealand for whom data are available. Causal mediation analysis is planned to estimate the effects of mediators on the relationship between the timing of cord clamping and the need for blood transfusion. The analysis is designed to discern whether initial severity of illness or the magnitude of placental transfusion mediates red blood cell transfusion dependence. Anticipated outcomes and dissemination We expect the study will identify potential strategies for reducing blood transfusions and associated negative outcomes in preterm infants. This will be relevant to researchers, clinicians, and parents. The results will be disseminated through publications, presentations, and inclusion in evidence-based guidelines.PMID:36081962 | PMC:PMC9440991 | DOI:10.7759/cureus.27693…

  • The effect of delayed umbilical cord clamping on Newborn's oxygen saturation and sucking success in primiparous pregnant

    J Obstet Gynaecol Res. 2022 Sep 5. doi: 10.1111/jog.15417. Online ahead of print.ABSTRACTAIM: The objective of this study was to examine the effect of delayed umbilical cord clamping on the newborn's oxygen saturation and sucking success in primiparas.METHODS: The study was conducted based on the experimental model with a control group, between March 15-November 10, 2020. The sample of the study consisted of 101 primiparous pregnant (48 primiparous with delayed cord clamping within 1-3 min and 53 primiparous with early cord clamping within 1 min) (having no high-risk pregnancy, 38-42 weeks, vaginal birth) in Turkey. The data were collected using a personal information form, the LATCH breastfeeding tool and the pulse oximetry. Statistical analyses were conducted using percentage distribution, arithmetic means, chi-square testing, and independent samples t-testing.RESULTS: Oxygen saturation values of newborns with delayed umbilical cord clamping were higher than those of newborns with early cord clamping. The saturation was first minute 66.43 versus 74.37, fifth minute 81.90 versus 88.60, tenth minute 91.77 versus 94.50 (p < 0.05). When compared to the group with early cord clamping, oxygen saturation is higher in the first by 11.95%, in the fifth by 8.18%, and in the tenth minute by 2.97% in the group with delayed cord clamping. The LATCH breastfeeding scores were found to be higher in the group with delayed cord clamping compared to the group with early cord clamping.CONCLUSION: It was determined that delayed cord clamping positively affected oxygen saturation values and sucking success in neonatal babies. Delayed umbilical cord clamping is an important issue that needs to be addressed in its different dimensions.PMID:36065164 | DOI:10.1111/jog.15417…

  • Neonatal breast-suckling skills in the context of lactation and peripartum hormonal changes and additional factors-a pilot study

    Int Breastfeed J. 2022 Sep 1;17(1):66. doi: 10.1186/s13006-022-00508-2.ABSTRACTBACKGROUND: Childbirth and lactation are intricate processes, involving several hormones, the most important of which are prolactin (a protein hormone) and cortisol (one of the glucocorticoids). The early postpartum period is crucial for both mother and newborn and has an impact on the lactation and breastfeeding process.METHODS: The study included 78 patients who were admitted to the Gynecology-Obstetrics Clinical Hospital in Poznań for labor induction and/or in the active phase of the first labor stage. The levels of cortisol and prolactin in serum were assessed in these women during admission in labor, during the third labor stage, and on the second day postpartum. The levels of cortisol and prolactin in the umbilical cord serum were assessed immediately after cord clamping. The "Protocol for the assessment of breast-suckling skills" was used to assess the neonatal breast-suckling skills on the second day postpartum. Some additional parameters were evaluated in mothers via a telephone interview at three and six months postpartum. The study was conducted from January to August 2020, however the study was suspended during April-July 2020 due to the SARS-CoV-2 pandemic, which led to restrictions in the hospital limiting access to the hospital wards unless necessary.RESULTS: Early breastfeeding with skin-to-skin contact was associated with low levels of hormones, cortisol levels were lower in serum (p = 0.0108) and umbilical vein (p = 0.0273) in mothers who breastfed immediately after childbirth. At three months postpartum, 88% of the mothers who did not offer a pacifier to the child during the first few days of life breastfed the child naturally (p = 0.037), and at six months, 96% of those who did not offer a pacifier continued to breastfeed (p = 0.0008). Multiple, statistically significant correlations were observed between the variables assessed according to the "Protocol for the assessment of breast-suckling skills" and breastfeeding after three months.CONCLUSIONS: Breastfeeding immediately after childbirth, appropriate assessment of the breast-suckling skills of newborns, avoiding pacifiers and infant formula feeding, and offering support to new mothers in the early days after childbirth seem to be important factors for sustaining breastfeeding after three and six months of childbirth.PMID:36050767 | PMC:PMC9436720 | DOI:10.1186/s13006-022-00508-2…

  • Early essential newborn care for cesarean section newborns in China: study protocol for a multi-centered randomized controlled trial

    Trials. 2022 Aug 19;23(1):696. doi: 10.1186/s13063-022-06615-z.ABSTRACTBACKGROUND: Early essential newborn care (EENC) is a package of evidence-based and cost-effective interventions delivered around birth mainly including delayed cord clamping, immediate and sustained skin-to-skin contact, and early initiation of exclusive breastfeeding. EENC is proven effective in promoting breastfeeding and improving women's and newborns' health. However, there is little evidence on implementation of EENC on newborns born by cesarean section in China. Therefore, the objective of this study is to assess the effectiveness of EENC intervention on rates of exclusive breastfeeding and early initiation of breastfeeding for cesarean section newborns in China.METHODS: This is a multi-centered, randomized controlled trial conducted in 4 tertiary hospitals in China. A total of 720 eligible women who will receive cesarean section are being randomized into four groups: control group (n=180), intervention group 1 (skin-to-skin contact for 30 min, n=180), intervention group 2 (skin-to-skin contact for 60 min, n=180), and intervention group 3 (skin-to-skin contact for 90 min, n=180). The control group will receive routine care, whereas the intervention groups will receive EENC with different duration of skin-to-skin contact. Demographic characteristics, clinical information, and breastfeeding outcomes will be collected. The primary outcome is rates of exclusive breastfeeding and early initiation of breastfeeding, and the secondary outcomes include maternal and neonatal morbidity and admissions.DISCUSSION: This study will provide evidence of the impact of EENC on improvement of breastfeeding outcomes and maternal and neonatal health for cesarean section newborns in China, and evidence-based recommendation to inform optimal duration of skin-to-skin contact for cesarean deliveries. The results of this study have potential to inform national-level guidelines and policy-making for optimizing EENC implementation for cesarean section newborns.TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2100048997.

  • Umbilical cord milking in nonvigorous infants: a cluster-randomized crossover trial

    Am J Obstet Gynecol. 2022 Aug 13:S0002-9378(22)00649-4. doi: 10.1016/j.ajog.2022.08.015. Online ahead of print.ABSTRACTBACKGROUND: Delayed cord clamping and umbilical cord milking provide placental transfusion to vigorous newborns. Delayed cord clamping in nonvigorous newborns may not be provided owing to a perceived need for immediate resuscitation. Umbilical cord milking is an alternative, as it can be performed more quickly than delayed cord clamping and may confer similar benefits.OBJECTIVE: We hypothesized that umbilical cord milking would reduce admission to the neonatal intensive care unit compared with early cord clamping in nonvigorous newborns born between 35 and 42 weeks' gestation.STUDY DESIGN: This was a pragmatic cluster-randomized crossover trial of infants born at 35 to 42 weeks' gestation in 10 medical centers in 3 countries between January 2019 and May 2021. The centers were randomized to umbilical cord milking or early cord clamping for approximately 1 year and then crossed over for an additional year or until the required number of consented subjects was reached. Waiver of consent as obtained in all centers to implement the intervention. Infants were eligible if nonvigorous at birth (poor tone, pale color, or lack of breathing in the first 15 seconds after birth) and were assigned to umbilical cord milking or early cord clamping according to their birth hospital randomization assignment. The baseline characteristics and outcomes were collected following deferred informed consent. The primary outcome was admission to the neonatal intensive care unit for predefined criteria. The main safety outcome was hypoxic-ischemic encephalopathy. Data were analyzed by the intention-to-treat concept.RESULTS: Among 16,234 screened newborns, 1780 were eligible (905 umbilical cord milking, 875 early cord clamping), and 1730 had primary outcome data for analysis (97% of eligible; 872 umbilical cord milking, 858 early cord clamping) either via informed consent (606 umbilical cord milking, 601 early cord clamping) or waiver of informed consent (266 umbilical cord milking, 257 early cord clamping). The difference in the frequency of neonatal intensive care unit admission using predefined criteria between the umbilical cord milking (23%) and early cord clamping (28%) groups did not reach statistical significance (modeled odds ratio, 0.69; 95% confidence interval, 0.41-1.14). Umbilical cord milking was associated with predefined secondary outcomes, including higher hemoglobin (modeled mean difference between umbilical cord milking and early cord clamping groups 0.68 g/dL, 95% confidence interval, 0.31-1.05), lower odds of abnormal 1-minute Apgar scores (Apgar ≤3, 30% vs 34%, crude odds ratio, 0.72; 95% confidence interval, 0.56-0.92); cardiorespiratory support at delivery (61% vs 71%, modeled odds ratio, 0.57; 95% confidence interval, 0.33-0.99), and therapeutic hypothermia (3% vs 4%, crude odds ratio, 0.57; 95% confidence interval, 0.33-0.99). Moderate-to-severe hypoxic-ischemic encephalopathy was significantly less common with umbilical cord milking (1% vs 3%, crude odds ratio, 0.48; 95% confidence interval, 0.24-0.96). No significant differences were observed for normal saline bolus, phototherapy, abnormal 5-minute Apgar scores (Apgar ≤6, 15.7% vs 18.8%, crude odds ratio, 0.81; 95% confidence interval, 0.62-1.06), or a serious adverse event composite of death before discharge.CONCLUSION: Among nonvigorous infants born at 35 to 42 weeks' gestation, umbilical cord milking did not reduce neonatal intensive care unit admission for predefined criteria. However, infants in the umbilical cord milking arm had higher hemoglobin, received less delivery room cardiorespiratory support, had a lower incidence of moderate-to-severe hypoxic-ischemic encephalopathy, and received less therapeutic hypothermia. These data may provide the first randomized controlled trial evidence that umbilical cord milking in nonvigorous infants is feasible, safe and, superior to early cord clamping.PMID:35970202 | DOI:10.1016/j.ajog.2022.08.015…

  • Hemoglobin differences in twins are related to the time of cord clamping, not intertwin transfusion - a prospective cohort study

    BMC Pregnancy Childbirth. 2022 Aug 5;22(1):619. doi: 10.1186/s12884-022-04942-2.ABSTRACTBACKGROUND: Delayed cord clamping increases placental transfusion. In vaginal deliveries higher hemoglobin concentrations are found in the second-born twin. We hypothesized it is unrelated to intertwin transfusion but to the time of cord clamping.METHODS: It was a prospective cohort study of 202 women delivering twins > 32 weeks of gestation. Monoamniotic pregnancy, antenatal intertwin transfusions, fetal demise or major abnormalities were excluded from the study. The time of cord clamping depended on the obstetrician's decision. Hemoglobin, hematocrit, and reticulocyte count were measured at birth and during the second day of life.RESULTS: At birth, hemoglobin and hematocrit levels were significantly higher in the first-born twins delivered with delayed than with early cord clamping. Higher hemoglobin and hematocrit levels were observed during the second day of life in all twins delivered with delayed cord clamping. The lowest levels were observed in twins delivered with early cord clamping. Infants delivered with delayed cord clamping were at a lower risk of respiratory disorders and NICU hospitalization.CONCLUSION: The observed differences in Hgb concentrations between the infants in a twin pregnancy are related to cord clamping time.PMID:35931974 | PMC:PMC9354348 | DOI:10.1186/s12884-022-04942-2…

  • A hybrid type I, multi-center randomized controlled trial to study the implementation of a method for Sustained cord circulation And VEntilation (the SAVE-method) of late preterm and term neonates: a study protocol

    BMC Pregnancy Childbirth. 2022 Jul 26;22(1):593. doi: 10.1186/s12884-022-04915-5.ABSTRACTBACKGROUND: An intact umbilical cord allows the physiological transfusion of blood from the placenta to the neonate, which reduces infant iron deficiency and is associated with improved development during early childhood. The implementation of delayed cord clamping practice varies depending on mode of delivery, as well as gestational age and neonatal compromise. Emerging evidence shows that infants requiring resuscitation would benefit if respiratory support were provided with the umbilical cord intact. Common barriers to providing intact cord resuscitation is the availability of neonatal resuscitation equipment close to the mother, organizational readiness for change as well as attitudes and beliefs about placental transfusion within the multidisciplinary team. Hence, clinical evaluations of cord clamping practice should include implementation outcomes in order to develop strategies for optimal cord management practice.METHODS: The Sustained cord circulation And Ventilation (SAVE) study is a hybrid type I randomized controlled study combining the evaluation of clinical outcomes with implementation and health service outcomes. In phase I of the study, a method for providing in-bed intact cord resuscitation was developed, in phase II of the study the intervention was adapted to be used in multiple settings. In phase III of the study, a full-scale multicenter study will be initiated with concurrent evaluation of clinical, implementation and health service outcomes. Clinical data on neonatal outcomes will be recorded at the labor and neonatal units. Implementation outcomes will be collected from electronic surveys sent to parents as well as staff and managers within the birth and neonatal units. Descriptive and comparative statistics and regression modelling will be used for analysis. Quantitative data will be supplemented by qualitative methods using a thematic analysis with an inductive approach.DISCUSSION: The SAVE study enables the safe development and evaluation of a method for intact cord resuscitation in a multicenter trial. The study identifies barriers and facilitators for intact cord resuscitation. The knowledge provided from the study will be of benefit for the development of cord clamping practice in different challenging clinical settings and provide evidence for development of clinical guidelines regarding optimal cord clamping.TRIAL REGISTRATION: Clinicaltrials.gov, NCT04070560 .

  • Umbilical cord arterial blood lactate dehydrogenase and pH as predictors of perinatal outcome in high-risk term pregnancies: a cohort study

    J Mother Child. 2022 Jul 20. doi: 10.34763/jmotherandchild.20222601.d-22-00004. Online ahead of print.ABSTRACTBACKGROUND: Birth asphyxia is a common cause of perinatal morbidity, mortality.OBJECTIVE: To compare the efficacy of umbilical cord arterial blood lactate dehydrogenase (LDH) and pH as predictors of neonatal outcome in high-risk term pregnancies using receiver operating characteristic (ROC) curves.MATERIAL AND METHODS: Present retrospective cohort study was conducted in the rural tertiary centre of Northern India over two years (January 2017-December 2018). Neonates delivered to 300 term (≥37 - ≤42 weeks) high-risk antenatal women were enrolled after fulfilling inclusion criteria. Immediately after delivery of a newborn by any mode, the segment of the umbilical cord (10 cm) was double clamped, cut, and arterial blood samples were taken for LDH and pH and were compared with neonatal outcome. Statistical analysis was done using SPSS 22.0 software.RESULTS: For all 300 neonates mean ± SD values of cord blood LDH and pH were 545.19 ± 391.93 U/L and 7.13 ± 0.15, respectively. High cord blood lactate and low pH values were significantly associated with adverse neonatal outcomes including neonatal resuscitation, NICU admission, complications and early neonatal deaths (p=0.000). The sensitivity, specificity and negative predictive value of cord blood LDH in the prediction of neonatal death was 100.00%, 53.17%, 100%, and pH was 93.75%, 53.17%, 99.34%, respectively.CONCLUSION: Cord blood lactate and pH help in the early prediction of neonatal outcomes, but cord blood lactate is a better predictor.PMID:35853688 | DOI:10.34763/jmotherandchild.20222601.d-22-00004…

  • Resuscitation of Term Compromised and Asphyctic Newborns: Better with Intact Umbilical Cord?

    Geburtshilfe Frauenheilkd. 2022 Jun 23;82(7):706-718. doi: 10.1055/a-1804-3268. eCollection 2022 Jul.ABSTRACTThe authors hypothesize that particularly severely compromised and asphyctic term infants in need of resuscitation may benefit from delayed umbilical cord clamping (after several minutes). Although evidence is sparse, the underlying pathophysiological mechanisms support this assumption. For this review the authors have analyzed the available research. Based on these data they conclude that it may be unfavorable to immediately clamp the cord of asphyctic newborns (e.g., after shoulder dystocia) although recommended in current guidelines to provide quick neonatological support. Compression of the umbilical cord or thorax obstructs venous flow to the fetus more than arterial flow to the placenta. The fetus is consequently cut off from a supply of oxygenated, venous blood. This may cause not only hypoxemia and consecutive hypoxia during delivery but possibly also hypovolemia. Immediate cord clamping may aggravate the situation of the already compromised newborn, particularly if the cord is cut before the lungs are ventilated. By contrast, delayed cord clamping leads to fetoplacental transfusion of oxygenated venous blood, which may buffer an existing acidosis. Furthermore, it may enhance blood volume by up to 20%, leading to higher levels of various blood components, such as red and white blood cells, thrombocytes, mesenchymal stem cells, immunoglobulins, and iron. In addition, the resulting increase in pulmonary perfusion may compensate for an existing hypoxemia or hypoxia. Early cord clamping before lung perfusion reduces the preload of the left ventricle and hinders the establishment of sufficient circulation. Animal models and clinical trials support this opinion. The authors raise the question whether it would be better to resuscitate compromised newborns with intact umbilical cords. Obstetric and neonatal teams need to work even closer together to improve neonatal outcomes.PMID:35815099 | PMC:PMC9262631 | DOI:10.1055/a-1804-3268…

  • A clinical study of fetal outcome following early and delayed cord clamping in births associated with anemia in pregnancy

    J Family Med Prim Care. 2022 May;11(5):1789-1793. doi: 10.4103/jfmpc.jfmpc_882_21. Epub 2022 May 14.ABSTRACTBACKGROUND: As there is a risk for infant anaemia, early cord clamping which is usually performed at 10-15 seconds of delivery was changed to delayed cord clamping for at least for 30 seconds Delayed cord clamping (DCC) increases the blood volume and haemoglobin levels in newborns and reduces risk of iron deficiency anaemia in both term and preterm infants.Early clamping allows cord blood collection in benefit for transplantation of stem cells.RESEARCH OBJECTIVE: To compare levels of haemoglobin, hematocrit and serum ferritin at birth and 4 weeks of age in babies as well as neonatal outcome following early and delayed cord clamping in births associated with anaemia in pregnancy.STUDY DESIGN: An observational study.PARTICIPANTS: Anaemic pregnant women with period of gestation 32-40 weeks admitted in labour room for delivery were enrolled. Intervention: Grouping of the patients was done according to the timing of the umbilical cord clamping. 1. Early cord clamping (< 60 seconds) 2. Delayed cord clamping (1 - 3 minutes) Of which 58 subjects were in ECC (early cord clamping)and 62 were in DCC (delayed cord clamping)group.RESULTS: There was no significance of ECC or DCC in developing polycythemia, IVH or hyperbilirubinemia or increased need of blood transfusion. The levels of haemoglobin, hematocrit and ferritin levels were showing significant increased among DCC as compared to ECC.CONCLUSION: Delayed cord clamping significantly increases the levels of haemoglobin, Serum ferritin and hematocrit at 4 weeks of age. It should be recommended in routine practice where it is not contraindicated especially in resource- poor settings.PMID:35800483 | PMC:PMC9254860 | DOI:10.4103/jfmpc.jfmpc_882_21…

  • Long-term impact of pre-incision antibiotics on children born by caesarean section: a longitudinal study based on UK electronic health records

    Health Technol Assess. 2022 Jun;26(30):1-160. doi: 10.3310/ZYZC8514.ABSTRACTBACKGROUND: Since changes in the national guidance in 2011, prophylactic antibiotics for women undergoing caesarean section are recommended prior to skin incision, rather than after the baby's umbilical cord has been clamped. Evidence from randomised controlled trials conducted outside the UK has shown that this reduces maternal infectious morbidity; however, the prophylactic antibiotics also cross the placenta, meaning that babies are exposed to them around the time of birth. Antibiotics are known to affect the gut microbiota of the babies, but the long-term effects of exposure to high-dose broad-spectrum antibiotics around the time of birth on allergy and immune-related diseases are unknown.OBJECTIVES: We aimed to examine whether or not in-utero exposure to antibiotics immediately prior to birth compared with no pre-incisional antibiotic exposure increases the risk of (1) asthma and (2) eczema in children born by caesarean section.DESIGN: This was a controlled interrupted time series study.SETTING: The study took place in primary and secondary care.PARTICIPANTS: Children born in the UK during 2006-18 delivered by caesarean section were compared with a control cohort delivered vaginally.INTERVENTIONS: In-utero exposure to antibiotics immediately prior to birth.MAIN OUTCOME MEASURES: Asthma and eczema in children in the first 5 years of life. Additional secondary outcomes, including other allergy-related conditions, autoimmune diseases, infections, other immune system-related diseases and neurodevelopmental conditions, were also assessed.DATA SOURCES: The Health Improvement Network (THIN) and the Clinical Practice Research Datalink (CPRD) primary care databases and the Hospital Episode Statistics (HES) database. Previously published linkage strategies were adapted to link anonymised data on mothers and babies in these databases. Duplicate practices contributing to both THIN and the CPRD databases were removed to create a THIN-CPRD data set.RESULTS: In the THIN-CPRD and HES data sets, records of 515,945 and 3,945,351 mother-baby pairs were analysed, respectively. The risk of asthma was not significantly higher in children born by caesarean section exposed to pre-incision antibiotics than in children whose mothers received post-cord clamping antibiotics, with an incidence rate ratio of 0.91 (95% confidence interval 0.78 to 1.05) for diagnosis of asthma in primary care and an incidence rate ratio of 1.05 (95% confidence interval 0.99 to 1.11) for asthma resulting in a hospital admission. We also did not find an increased risk of eczema, with an incidence rate ratio of 0.98 (95% confidence interval 0.94 to1.03) and an incidence rate ratio of 0.96 (95% confidence interval 0.71 to 1.29) for diagnosis in primary care and hospital admissions, respectively.LIMITATIONS: It was not possible to ascertain the exposure to pre-incision antibiotics at an individual level. The maximum follow-up of children was 5 years.CONCLUSIONS: There was no evidence that the policy change from post-cord clamping to pre-incision prophylactic antibiotics for caesarean sections during 2006-18 had an impact on the incidence of asthma and eczema in early childhood in the UK.FUTURE WORK: There is a need for further research to investigate if pre-incision antibiotics have any impact on developing asthma and other allergy and immune-related conditions in older children.STUDY REGISTRATION: This study is registered as researchregistry3736.FUNDING: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 30.

  • A systematic review of newborn health interventions in humanitarian settings

    BMJ Glob Health. 2022 Jul;7(7):e009082. doi: 10.1136/bmjgh-2022-009082.ABSTRACTBACKGROUND: Almost half of the under-5 deaths occur in the neonatal period and most can be prevented with quality newborn care. The already vulnerable state of newborns is exacerbated in humanitarian settings. This review aims to assess the current evidence of the interventions being provided in these contexts, identify strategies that increase their utilisation and their effects on health outcomes in order to inform involved actors in the field and to guide future research.METHODS: Searched for peer-reviewed and grey literature in four databases and in relevant websites, for published studies between 1990 and 15 November 2021. Search terms were related to newborns, humanitarian settings, low-income and middle-income countries and newborn health interventions. Quality assessment using critical appraisal tools appropriate to the study design was conducted. Data were extracted and analysed using a narrative synthesis approach.RESULTS: A total of 35 articles were included in this review, 33 peer-reviewed and 2 grey literature publications. The essential newborn care (ENC) interventions reported varied across the studies and only three used the Newborn Health in Humanitarian Settings: Field Guide as a guideline document. The ENC interventions most commonly reported were thermal care and feeding support whereas delaying of cord clamping and administration of vitamin K were the least. Training of healthcare workers was the most frequent strategy reported to increase utilisation. Community interventions, financial incentives and the provision of supplies and equipment were also reported.CONCLUSION: There is insufficient evidence documenting the reality of newborn care in humanitarian settings in low-income and middle-income countries. There is a need to improve the reporting of these interventions, including when there are gaps in service provision. More evidence is needed on the strategies used to increase their utilisation and the effect on health outcomes.PROSPERO REGISTRATION NUMBER: CRD42020199639.PMID:35777926 | PMC:PMC9252185 | DOI:10.1136/bmjgh-2022-009082…

  • Quality improvement for neonatal resuscitation and delivery room care

    Semin Perinatol. 2022 Oct;46(6):151629. doi: 10.1016/j.semperi.2022.151629. Epub 2022 May 21.ABSTRACTQuality improvement has become a foundation of neonatal care. Structured approaches to improvement can standardize practices, improve teamwork, engage families, and improve outcomes. The delivery room presents a unique environment for quality improvement; optimal delivery room care requires advanced preparation, adequately trained providers, and carefully coordinated team dynamics. In this article, we examine quality improvement for neonatal resuscitation. We review the published literature, focusing on reports targeting admission hypothermia, delayed cord clamping, and initial respiratory support. We discuss specific challenges related to delivery room quality improvement, including small numbers, data collection, and lack of benchmarking, and potential strategies to address them including simulation, checklists, and state and national collaboratives. We examine how quality improvement can target equity in delivery room outcomes, and explore the impact of the COVID-19 pandemic on delivery room quality of care.PMID:35753831 | PMC:PMC9124044 | DOI:10.1016/j.semperi.2022.151629…

  • Delayed versus early umbilical cord clamping for near-term infants born to preeclamptic mothers; a randomized controlled trial

    BMC Pregnancy Childbirth. 2022 Jun 25;22(1):515. doi: 10.1186/s12884-022-04831-8.ABSTRACTOBJECTIVE: This study aims to assess delayed versus early umbilical cord clamping in preeclamptic mothers undergoing scheduled caesarean delivery regarding the maternal intra-operative blood loss and neonatal outcomes.METHODS: A clinical trial was conducted on 62 near-term preeclamptic mothers (36-38+6 weeks) who were planned for caesarean delivery. They were randomly assigned into two groups. The first group was the early cord clamping (ECC) group (n= 31), in which clamping the umbilical cord was within 15 seconds, while the second group was the delayed cord clamping (DCC) group (n= 31), in which clamping the umbilical cord was at 60 seconds. All patients were assessed for intra-operative blood loss and incidence of primary postpartum haemorrhage (PPH). Otherwise, all neonates were assessed for APGAR scores, the need for the neonatal intensive care unit (NICU) admission due to jaundice, and blood tests (haemoglobin, haematocrit. and serum bilirubin).RESULTS: There was not any significant difference between the two groups regarding the maternal estimated blood loss (P=0.673), the rates of PPH (P=0.1), post-delivery haemoglobin (P=0.154), and haematocrit values (P=0.092). Neonatal outcomes also were showing no significant difference regarding APGAR scores at the first minute (P=1) and after 5 minutes (P=0.114), day 1 serum bilirubin (P=0.561), day 3 serum bilirubin (P=0.676), and the rate of NICU admission (P=0.671). However, haemoglobin and haematocrit values were significantly higher in the DCC group than in the ECC group (P<0.001).CONCLUSION: There is no significant difference between DCC and ECC regarding maternal blood loss. However, DCC has the advantage of significantly higher neonatal haemoglobin.TRIAL REGISTRATION: It was first registered at ClinicalTrials.gov on 10/12/2019 with registration number NCT04193345.PMID:35752762 | PMC:PMC9233844 | DOI:10.1186/s12884-022-04831-8…

  • Differential effects of delayed cord clamping on bilirubin levels in normal and diabetic pregnancies

    Eur J Pediatr. 2022 Aug;181(8):3111-3117. doi: 10.1007/s00431-022-04536-2. Epub 2022 Jun 25.ABSTRACTThe purpose of the study is to investigate the effects of delayed cord clamping on bilirubin levels and phototherapy rates in neonates of diabetic mothers. This was a prospective study that enrolled pregnant women without pregnancy complications and those with diabetes. Their neonates were randomized in a 1:1 ratio to delayed cord clamping. The main outcomes were the neonatal transcutaneous bilirubin values on 2-4 days postpartum and the rate of requiring phototherapy in infants. A total of 261 pregnant women were included in the final analysis (132 women with diabetic pregnancies and 129 women with normal pregnancies). In diabetic pregnancies, neonatal bilirubin levels on the 2-4 days postpartum and phototherapy rates were significantly higher in the delayed cord clamping group than in the immediate cord clamping group (7.65 ± 1.83 vs 8.25 ± 1.96, P = 0.039; 10.35 ± 2.23 vs 11.54 ± 2.56, P = 0.002; 11.54 ± 2.94 vs 12.83 ± 3.07 P = 0.024, 18.2% vs 6.3%, P = 0.042), while in normal pregnancies, there was no statistical difference in bilirubin values and phototherapy rates between the delayed cord clamping group and the immediate cord clamping group (P > 0.05). After receiving delayed cord clamping, bilirubin levels on the third postnatal day and the rate of requiring phototherapy in infants were higher in the diabetic pregnancy group than in the normal pregnancy group (10.35 ± 2.23 vs 11.54 ± 2.56, P = 0.013).CONCLUSION: Delayed cord clamping increased the risk of jaundice in newborns born to diabetic mothers, but had no effect in newborns from mothers with normal pregnancies. DCC may be a risk factor for increased bilirubin in infants of diabetic mothers.TRIAL REGISTRATION: ClinicalTrials.gov: NCT04369313; date of registration: April 27, 2020 (retrospectively registered).WHAT IS KNOWN: • Delayed cord clamping had significant benefits for newborns by increasing neonatal hemoglobin levels and reducing the risk of neonatal anemia, etc. • Delayed cord clamping may lead to neonatal hyperemia, erythrocytosis, and hyperbilirubinemia, which increases the risk of neonatal jaundice.WHAT IS NEW: • Our trial focused on the differential effects of delayed cord clamping on jaundice in full-term newborns between diabetic pregnancies and normal pregnancies. And newborns of diabetic mothers who received delayed cord clamping had a significantly increased risk of jaundice compared to newborns with normal pregnancy. • Delayed cord clamping may be a risk factor for increased bilirubin levels in neonates of diabetic mothers.PMID:35751710 | DOI:10.1007/s00431-022-04536-2…

  • Physiologically based cord clamping for infants ≥32+0 weeks gestation: A randomised clinical trial and reference percentiles for heart rate and oxygen saturation for infants ≥35+0 weeks gestation

    PLoS Med. 2022 Jun 23;19(6):e1004029. doi: 10.1371/journal.pmed.1004029. eCollection 2022 Jun.ABSTRACTBACKGROUND: Globally, the majority of newborns requiring resuscitation at birth are full term or late-preterm infants. These infants typically have their umbilical cord clamped early (ECC) before moving to a resuscitation platform, losing the potential support of the placental circulation. Physiologically based cord clamping (PBCC) is clamping the umbilical cord after establishing lung aeration and holds promise as a readily available means of improving early newborn outcomes. In mechanically ventilated lambs, PBCC improved cardiovascular stability and reduced hypoxia. We hypothesised that PBCC compared to ECC would result in higher heart rate (HR) in infants needing resuscitation, without compromising safety.METHODS AND FINDINGS: Between 4 July 2018 and 18 May 2021, infants born at ≥32+0 weeks' gestation with a paediatrician called to attend were enrolled in a parallel-arm randomised trial at 2 Australian perinatal centres. Following initial stimulation, infants requiring further resuscitation were randomised within 60 seconds of birth using a smartphone-accessible web link. The intervention (PBCC) was to establish lung aeration, either via positive pressure ventilation (PPV) or effective spontaneous breathing, prior to cord clamping. The comparator was early cord clamping (ECC) prior to resuscitation. The primary outcome was mean HR between 60 to 120 seconds after birth, measured using 3-lead electrocardiogram, extracted from video recordings blinded to group allocation. Nonrandomised infants had deferred cord clamping (DCC) ≥120 seconds in the observational study arm. Among 508 at-risk infants enrolled, 123 were randomised (n = 63 to PBCC, n = 60 to ECC). Median (interquartile range, IQR) for gestational age was 39.9 (38.3 to 40.7) weeks in PBCC infants and 39.6 (38.4 to 40.4) weeks in ECC infants. Approximately 49% and 50% of the PBCC and ECC infants were female, respectively. Five infants (PBCC = 2, ECC = 3, 4% total) had missing primary outcome data. Cord clamping occurred at a median (IQR) of 136 (126 to 150) seconds in the PBCC arm and 37 (27 to 51) seconds in the ECC arm. Mean HR between 60 to 120 seconds after birth was 154 bpm (beats per minute) for PBCC versus 158 bpm for ECC (adjusted mean difference -6 bpm, 95% confidence interval (CI) -17 to 5 bpm, P = 0.39). Among 31 secondary outcomes, postpartum haemorrhage ≥500 ml occurred in 34% and 32% of mothers in the PBCC and ECC arms, respectively. Two hundred ninety-five nonrandomised infants (55% female) with median (IQR) gestational age of 39.6 (38.6 to 40.6) weeks received DCC. Data from these infants was used to create percentile charts of expected HR and oxygen saturation in vigorous infants receiving DCC. The trial was limited by the small number of infants requiring prolonged or advanced resuscitation. PBCC may provide other important benefits we did not measure, including improved maternal-infant bonding and higher iron stores.CONCLUSIONS: In this study, we observed that PBCC resulted in similar mean HR compared to infants receiving ECC. The findings suggest that for infants ≥32+0 weeks' gestation who receive brief, effective resuscitation at closely monitored births, PBCC does not provide additional benefit over ECC (performed after initial drying and stimulation) in terms of key physiological markers of transition. PBCC was feasible using a simple, low-cost strategy at both cesarean and vaginal births. The percentile charts of HR and oxygen saturation may guide clinicians monitoring the transition of at-risk infants who receive DCC.TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12618000621213.PMID:35737735 | PMC:PMC9269938 | DOI:10.1371/journal.pmed.1004029…

  • Physiology of neonatal resuscitation: Giant strides with small breaths

    Semin Perinatol. 2022 Oct;46(6):151620. doi: 10.1016/j.semperi.2022.151620. Epub 2022 May 21.ABSTRACTThe transition of a fetus to a newborn involves a sequence of well-orchestrated physiological events. Most neonates go through this transition without assistance but 5-10% may require varying degrees of resuscitative interventions at birth. The most crucial event during this transition is lung inflation with optimal concentrations of oxygen. Rarely, extensive resuscitation including chest compressions and medication may be required. In the past few decades, significant strides have been made in our understanding of the cardiorespiratory transition at birth from a fetus to a newborn and the subsequent resuscitation. This article reviews the physiology behind neonatal transition at birth and various interventions during neonatal resuscitation.PMID:35715254 | DOI:10.1016/j.semperi.2022.151620…

  • Gestational Age-Specific Nomogram of Transcutaneous Bilirubin in First 120 h of Life for Term and Late Preterm Indian Neonates

    J Trop Pediatr. 2022 Jun 6;68(4):fmac047. doi: 10.1093/tropej/fmac047.ABSTRACTOBJECTIVE: To create a nomogram based on transcutaneous bilirubin values (TCB) in first week of life for term and late preterm (>34 weeks) neonates.METHODS AND DESIGN: Prospective longitudinal study.SETTING: Four tertiary-care teaching hospitals (one each in eastern and southern India, two in northern India) between February 2019 and March 2020.PARTICIPANTS: A total of 2492 term and late preterm (>34 weeks) neonates.INTERVENTION: Bilirubin was measured by transcutaneous bilirubinometer (Drager JM-105, Germany) in all neonates in pre-specified times of the day, 12 hourly every day since birth till discharge between 48 and 72 h, and data were recorded in epochs of 6 hourly intervals. Post-discharge, all neonates were called for review in next 48 h.OUTCOME MEASURES: Primary-TCB in first week of life. Secondary-factors having significant association with significant hyperbilirubinaemia requiring phototherapy.RESULTS: Total of 2492 neonates (males 1303 and female 1189), with a total of 14 162 TCB recordings were analysed and mean hourly bilirubin (TCB) at hourly intervals till 120 h and then daily bilirubin values on Days 6 and 7 were tabulated. We have constructed hour-specific bilirubin nomogram with percentiles as per gestational age in term and near-term Indian neonates till 120 h of life. Amongst the known risk factors, delayed cord clamping, primipara and breastfeeding jaundice had significant association for hyperbilirubinaemia needing phototherapy.CONCLUSIONS: We have created gestation-specific nomogram of TCB levels in 6 hourly intervals for the first 120 postnatal hours, obtained from a large predominantly breast fed healthy, term and near-term Indian neonates.PMID:35666181 | DOI:10.1093/tropej/fmac047…

  • Implementation of Delayed Cord Clamping in public health facilities: a case study from India

    BMC Pregnancy Childbirth. 2022 Jun 1;22(1):457. doi: 10.1186/s12884-022-04771-3.ABSTRACTBACKGROUND: Global and country specific recommendations on Delayed umbilical cord clamping (DCC) are available, though guidance on their implementation in program settings is lacking. In India, DCC (clamping not earlier than 1 min after birth) is a component in the package of services delivered as part of the India Newborn Action Plan (INAP) supported by Nutrition International (NI) in two states. The objective of this case study was to document the learnings from implementation of DCC in these two states and to understand the health system factors that affected its operationalization.METHODS: Mixed methods were followed. Using the World Health Organization (WHO) Health Systems building blocks as a framework, 20 Key-Informant Interviews were conducted to explore facilitators and barriers to routine implementation of DCC in public health settings. Existing quantitative program data and secondary data from labour-room registers from eight NI- supported districts were analysed to assess the prevalence of DCC implementation in public health systems settings.RESULTS: A demonstrated commitment from the government to implement DCC at all delivery points in NI supported districts was observed. Funds were sufficient, trainings were optimal, knowledge of the health workforce was adequate and a recording mechanism was in place. According to record reviews, DCC was more likely to happen in facilities that provide Basic Emergency Obstetric services and among normal deliveries. It was less likely to be followed in babies delivered by Caesarean section (OR 0.03; 95%CI 0.02,0.05), birthweight < 2000 g (OR 0.22; 95%CI 0.12,0.47), multiple pregnancies (OR 0.17, 95%CI 0.05,0.63), birth asphyxia requiring resuscitation (0.37; 95%CI 0.26,0.52), and those delivered during day shift (OR 0.59, 95%CI 0.40, 0.83).CONCLUSIONS: Wide coverage of DCC in public health settings in the two states was observed. Good governance, adequate funding, commitment of health workforce has likely contributed to its success in these contexts. These are critical elements to guide DCC implementation in India and for consideration in other settings.PMID:35650543 | PMC:PMC9158298 | DOI:10.1186/s12884-022-04771-3…

  • Quality newborn care in East New Britain, Papua New Guinea: measuring early newborn care practices and identifying opportunities for improvement

    BMC Pregnancy Childbirth. 2022 Jun 1;22(1):462. doi: 10.1186/s12884-022-04735-7.ABSTRACTBACKGROUND: Renewed attention and investment is needed to improve the quality of care during the early newborn period to address preventable newborn deaths and stillbirths in Papua New Guinea (PNG). We aimed to assess early newborn care practices and identify opportunities for improvement in one province (East New Britain) in PNG.METHODS: A mixed-methods study was undertaken in five rural health facilities in the province using a combination of facility audits, labour observations and qualitative interviews with women and maternity providers. Data collection took place between September 2019 and February 2020. Quantitative data were analysed descriptively, whilst qualitative data were analysed using content analysis. Data were triangulated by data source.RESULTS: Five facility audits, 30 labour observations (in four of the facilities), and interviews with 13 women and eight health providers were conducted to examine early newborn care practices. We found a perinatal mortality rate of 32.2 perinatal deaths per 1000 total births and several barriers to quality newborn care, including an insufficient workforce, critical infrastructure and utility constraints, and limited availability of essential newborn medicines and equipment. Most newborns received at least one essential newborn care practice in the first hour of life, such as immediate and thorough drying (97%).CONCLUSIONS: We observed high rates of essential newborn care practices including immediate skin-to-skin and delayed cord clamping. We also identified multiple barriers to improving the quality of newborn care in East New Britain, PNG. These findings can inform the development of effective interventions to improve the quality of newborn care. Further, this study demonstrates that multi-faceted programs that include increased investment in the health workforce, education and training, and availability of essential equipment, medicines, and supplies are required to improve newborn outcomes.PMID:35650540 | PMC:PMC9157041 | DOI:10.1186/s12884-022-04735-7…

  • Influence of umbilical cord milking versus delayed cord clamping on the early prognosis of preterm infants with a gestational age of &lt;34 weeks: a Meta analysis

    Zhongguo Dang Dai Er Ke Za Zhi. 2022 May 15;24(5):492-499. doi: 10.7499/j.issn.1008-8830.2112088.ABSTRACTOBJECTIVES: To study the influence of umbilical cord milking versus delayed cord clamping on the early prognosis of preterm infants with a gestational age of <34 weeks.METHODS: PubMed, Web of Science, Embase, the Cochrane Library, CINAHL, China National Knowledge Infrastructure, Wanfang Data, Weipu Database, and SinoMed were searched for randomized controlled trials on umbilical cord milking versus delayed cord clamping in preterm infants with a gestational age of <34 weeks published up to November 2021. According to the inclusion and exclusion criteria, two researchers independently performed literature screening, quality evaluation, and data extraction. Review Manger 5.4 was used for Meta analysis.RESULTS: A total of 11 articles were included in the analysis, with 1 621 preterm infants in total, among whom there were 809 infants in the umbilical cord milking group and 812 in the delayed cord clamping group. The Meta analysis showed that compared with delayed cord clamping, umbilical cord milking increased the mean blood pressure after birth (weighted mean difference=3.61, 95%CI: 0.73-6.50, P=0.01), but it also increased the incidence rate of severe intraventricular hemorrhage (RR=1.83, 95%CI: 1.08-3.09, P=0.02). There were no significant differences between the two groups in hemoglobin, hematocrit, blood transfusion rate, proportion of infants undergoing phototherapy, bilirubin peak, and incidence rates of complications such as periventricular leukomalacia and necrotizing enterocolitis (P>0.05).CONCLUSIONS: Compared with delayed cord clamping, umbilical cord milking may increase the risk of severe intraventricular hemorrhage in preterm infants with a gestational age of <34 weeks; however, more high-quality large-sample randomized controlled trials are needed for further confirmation.PMID:35644188 | PMC:PMC9154370 | DOI:10.7499/j.issn.1008-8830.2112088…

  • Cardiopulmonary Resuscitation with an Intact Umbilical Cord

    Neoreviews. 2022 Jun 1;23(6):e388-e399. doi: 10.1542/neo.23-6-e388.ABSTRACTThe body of literature supporting different umbilical management strategies has increased over the past decade as the role of cord management in neonatal transition is realized. Multiple international governing bodies endorse delayed cord clamping, and this practice is now widely accepted by obstetricians and neonatologists. Although term and preterm neonates benefit in some ways from delayed cord clamping, additional research on variations in this practice, including resuscitation with an intact cord, aim to find the optimal cord management practice that reduces mortality and major morbidities.PMID:35641463 | DOI:10.1542/neo.23-6-e388…

  • Disseminated intravascular coagulation complicated by amniotic band syndrome associated with deceased fetal umbilical cord following fetoscopic laser surgery

    J Obstet Gynaecol Res. 2022 Jul;48(7):1989-1996. doi: 10.1111/jog.15281. Epub 2022 May 25.ABSTRACTFetoscopic laser surgery occasionally causes amniotic band syndrome, in which the disrupted amniotic membrane constricts fetal body parts, leading to functional or morphological loss. We report a case of fetal distress at 31 weeks of gestation in the larger surviving twin after fetoscopic laser surgery for selective intrauterine growth restriction, necessitating emergent cesarean section. Physical examination of the infant showed constriction rings caused by a disrupted amniotic membrane on the digits, and the distal part of the right index finger was necrotic because of tight strangulation by an amniotic band with the umbilical cord of the deceased smaller twin. Laboratory data showed severe coagulopathy, and the infant was diagnosed with disseminated intravascular coagulation (DIC). Immediate treatment improved his condition. DIC may have been associated with the necrotic finger, which was strangulated by the umbilical cord of the deceased fetus, because neither maternal coagulopathy nor an underlying neonatal disorder was detected.PMID:35614528 | DOI:10.1111/jog.15281…

  • Sustaining immediate newborn care processes (delayed cord clamping and early breastfeeding initiation) in the delivery room: a quality improvement study

    BMJ Open Qual. 2022 May;11(Suppl 1):e001705. doi: 10.1136/bmjoq-2021-001705.ABSTRACTBACKGROUND: Immediate newborn care processes like delayed cord clamping (DCC) and early breastfeeding initiation (EBFI) in the delivery room have several benefits including survival. Despite the evidence, the practices have not been widely adopted. We used a point-of-care quality improvement (QI) to implement and sustain these two immediate newborn care processes in our delivery room over a period of 2 years through a series of plan-do-study-act (PDSA) cycles.METHODS: All neonates above 30 weeks of gestation irrespective of the need for resuscitation except Rh-isoimmunisation were eligible for DCC. Neonates >35 weeks not requiring respiratory support or resuscitation were eligible for EBFI. The root causes of gaps in the quality were analysed by fishbone analysis. The key quantitative outcome measure was the percentage of eligible deliveries in which DCC and EBFI were done. Duration of DCC was also recorded in the sustenance phase. This implementation was done through three PDSA cycles and the practices were sustained for 2 years.RESULTS: A total of 770 deliveries were part of this QI study from October 2018 to December 2020. There was a significant improvement in DCC (median) from a baseline of 25% to 96% over a 2-year period. Sensitisation, making DCC part of pre-birth checklist and recording outcomes on a dashboard daily helped to implement and sustain the processes over 2 years. As a co-process, EBFI improved (median) from a baseline of 50% to 97% without any major intervention in the system.CONCLUSIONS: Immediate newborn care processes could be sustained by making them part of pre-birth preparation and dashboard recording by a QI initiative without any additional resources.PMID:35584842 | PMC:PMC9119176 | DOI:10.1136/bmjoq-2021-001705…

  • Integrated review of the knowledge, attitudes, and practices of maternity health care professionals concerning umbilical cord clamping

    Birth. 2022 May 18. doi: 10.1111/birt.12647. Online ahead of print.ABSTRACTBACKGROUND: Umbilical cord clamp timing has implications for newborn health, which include increased iron stores up to 6 months of age. National and International cord clamping guidelines differ as do health professionals' practices. The rationale for differences in cord clamping practice is unclear.AIMS AND OBJECTIVE: Studies on the knowledge, attitudes, and practices of maternity health care professionals about cord clamp timing were synthesized. Similarities and differences between professional groups and understanding of the optimal timing of cord clamp timing for term newborns were compared.METHODS: An integrative review was undertaken. PubMed, Scopus, MIDIRS, CINAHL, and Google Scholar were searched. Publication date limits were set between January 2007 and December 2020. Quality appraisal was undertaken using the Critical Appraisal Skills Program (CASP) tools.RESULTS: Eighteen studies met inclusion criteria, as they included primary research studies that investigated maternity health care professionals' knowledge, attitudes, and practices about umbilical cord clamping, and were written in English. Four main subject areas were identified: a) knowledge of optimal cord clamp timing; b) attitudes and perceptions of early vs deferred cord clamping; c) cord clamping practice; and d) rationale for cord clamping practice.CONCLUSIONS: Different attitudes and practices were identified between midwifery and medical professionals in relation to cord clamp timing together with health professional knowledge and practice gaps pertaining to optimal cord clamp timing. Contemporary evidence should inform guidelines for clinical practice and be embedded into maternity health professional curricula and professional development programs.PMID:35582849 | DOI:10.1111/birt.12647…

  • Neurodevelopmental Outcomes of Infants at &lt;29 Weeks of Gestation Born in Canada Between 2009 and 2016

    J Pediatr. 2022 Aug;247:60-66.e1. doi: 10.1016/j.jpeds.2022.04.048. Epub 2022 May 11.ABSTRACTOBJECTIVE: To evaluate changes in mortality or significant neurodevelopmental impairment (NDI) in children born at <29 weeks of gestation in association with national quality improvement initiatives.STUDY DESIGN: This longitudinal cohort study included children born at 220/7 to 286/7 weeks of gestation who were admitted to Canadian neonatal intensive care units between 2009 and 2016. The primary outcome was a composite rate of death or significant NDI (Bayley Scales of Infant and Toddler Development, Third Edition score <70, severe cerebral palsy, blindness, or deafness requiring amplification) at 18-24 months corrected age. To evaluate temporal changes, outcomes were compared between epoch 1 (2009-2012) and epoch 2 (2013-2016). aORs were calculated for differences between the 2 epochs accounting for differences in patient characteristics.RESULTS: The 4426 children included 1895 (43%) born in epoch 1 and 2531 (57%) born in epoch 2. Compared with epoch 1, in epoch 2 more mothers received magnesium sulfate (56% vs 28%), antibiotics (69% vs 65%), and delayed cord clamping (37% vs 31%) and fewer infants had a Score for Neonatal Acute Physiology, version II >20 (31% vs 35%) and late-onset sepsis (23% vs 27%). Death or significant NDI occurred in 30% of children in epoch 2 versus 32% of children in epoch 1 (aOR, 0.86; 95% CI, 0.75-0.99). In epoch 2, there were reductions in the need for hearing aids or cochlear implants (1.4% vs 2.6%; aOR, 0.50; 95% CI, 0.31-0.82) and in blindness (0.6% vs.1.4%; aOR, 0.38; 95% CI, 0.18-0.80).CONCLUSIONS: Among preterm infants born at <29 weeks of gestation, composite rates of death or significant NDI and rates of visual and hearing impairment were significantly lower in 2013-2016 compared with 2009-2012.PMID:35561804 | DOI:10.1016/j.jpeds.2022.04.048…

  • Assessing Implementation of Helping Babies Breathe Program Through Observing Immediate Care of Neonates at Time of Delivery

    Front Pediatr. 2022 Apr 25;10:864431. doi: 10.3389/fped.2022.864431. eCollection 2022.ABSTRACTBACKGROUND: Training in neonatal resuscitation has been shown to reduce deaths related to intrapartum asphyxia. Helping Babies Breathe (HBB) is a simulation-based program focusing on training healthcare providers (HCPs) in immediate neonatal care including stimulation, initiating bag mask ventilation (BMV) in the absence of breathing by 1 min of life, and delayed (30-60 s after birth) umbilical cord clamping (DCC). Data on implementation of HBB posttraining are limited.OBJECTIVE: To determine time from birth to spontaneous breathing, cord clamping, and initiation of BMV in a setting where the majority of HCPs are HBB trained.METHODS: Two research nurses observed deliveries conducted in two referral hospitals. Timing included the onset of breathing, cord clamping, and initiation of BMV. Deliveries were grouped according to the mode of delivery.RESULTS: In total, 496 neonates were observed; 410 (82.7%) neonates cried or had spontaneous breathing (median time 17 s) soon after birth, 25/86 (29%) of neonates not breathing responded to stimulation, 61 (12.3%) neonates required BMV, and 2 (0.4%) neonates required chest compression and/or adrenalin. Neonates delivered by cesarean section (CS) took longer to initiate first breath than those delivered vaginally (median time 19 vs. 14 s; p = 0.009). Complete data were available in 58/61 (95%) neonates receiving BMV, which was initiated in 54/58 (93%) cases within 60 s of life (the "Golden Minute"). Median time to cord clamping was 74 s, with 414 (83.5%) and 313 (63.0%) having cord clamped at ≥ 30 and ≥ 60 s, respectively. Factors associated with BMV were CS delivery [odds ratio (OR) 29.9; 95% CI 3.37-229], low birth weight (LBW) (birthweight < 2,500 g) (OR 2.47; 95% CI 1.93-5.91), and 1 min Apgar score < 7 (OR 149; 95% CI 49.3-5,021). DCC (≥ 60 s) was less likely following CS delivery (OR 0.14; 95% CI 0.02-0.99) and being LBW (OR 0.43; 95% CI 0.24-0.77).CONCLUSION: Approximately 83% of neonates initiated spontaneous breathing soon after birth and 29% of neonates not breathing responded to physical stimulation. BMV was initiated within the Golden Minute in most neonates, but under two-thirds had DCC (≥60 s). HBB implementation followed guidelines, suggesting that knowledge and skills taught from HBB are retained and applied by HCP.PMID:35547538 | PMC:PMC9083269 | DOI:10.3389/fped.2022.864431…

  • Evidence-based labor management: third stage of labor (part 5)

    Am J Obstet Gynecol MFM. 2022 Sep;4(5):100661. doi: 10.1016/j.ajogmf.2022.100661. Epub 2022 May 7.ABSTRACTDuring the third stage of labor, oxytocin and tranexamic acid, oxytocin and misoprostol, oxytocin and methylergometrine, or carbetocin is recommended for the prevention of postpartum hemorrhage after vaginal delivery. Intravenous oxytocin (10 IU) immediately after delivery of the neonate (after either anterior shoulder or whole-body delivery) and before delivery of the placenta is recommended. If oxytocin and tranexamic acid combination is chosen, intravenous tranexamic acid (1 g) in addition to intravenous oxytocin (10 IU) immediately after delivery of the neonate and before placental delivery is recommended. If oxytocin and misoprostol combination is chosen, sublingual misoprostol (400 µg) in addition to intravenous oxytocin (10 IU) immediately after delivery of the neonate is recommended. If there is no intravenous access or if in low-resource settings, sublingual misoprostol (400 µg) and intramuscular oxytocin (10 IU) are recommended. If oxytocin and methylergometrine combination is chosen, intramuscular methylergometrine (0.2 mg) and intravenous oxytocin (10 IU) immediately after delivery of the neonate are recommended. Single-dose intravenous or intramuscular carbetocin (100 µg) immediately after delivery of the neonate is recommended. Controlled cord traction and delayed cord clamping for approximately 60 seconds is recommended. There is insufficient evidence to support or refute umbilical cord milking, uterine massage, or nipple stimulation for the prevention of postpartum hemorrhage. Repair of first- and second-degree lacerations with continuous synthetic suture technique is recommended. No repair of first-degree lacerations if hemostatic and normal cosmesis can be considered. Repair of third-degree lacerations with end-to-end or overlap continuous synthetic suture technique is recommended. Repair of fourth-degree lacerations with delayed absorbable 4-0 or 3-0 polyglactin or chromic suture in a running fashion is recommended. The use of single-dose second-generation cephalosporin at the time of third- or fourth-degree laceration repairs can be considered. Skin-to-skin contact after delivery is recommended. There is insufficient evidence to support or refute routine cord blood gas sampling after delivery. Public cord blood banking is recommended.PMID:35537683 | DOI:10.1016/j.ajogmf.2022.100661…

  • Hemodynamic parameters after Delayed Cord Clamping (DCC) in term neonates: a prospective observational study

    BMC Pediatr. 2022 May 6;22(1):256. doi: 10.1186/s12887-022-03303-4.ABSTRACTBACKGROUND: Delayed cord clamping (DCC) is practiced worldwide, as standard care in both term and preterm babies. Our aim was to determine the hemodynamic effects of DCC on transitional circulation.MATERIAL AND METHODS: This prospective observational study was carried out in a tertiary care hospital, at Pune, India, from May 2018 to October 2019.Term neonates born during the study period were included. The primary outcome variables of the study were right ventricular output (RVO), left ventricular output (LVO), superior vena cava (SVC) flow (ml/kg/min) and heart rate(HR) at 12 ± 6 and 48 ± 6 h of life measured by point of care functional echocardiography. Inter-observer and intra-observer variability was calculated for these parameters.RESULTS: Out of a total of 2744 deliveries during the study period, 620 babies were included. Mean gestational age of the enrolled babies was 38.96 ± 1.08 weeks and mean birth weight was 2.9 ± 0.39 kg. Mean heart rate of babies recorded at 12 ± 6 h of life was 127 beats per minute (bpm) whereas it was 128 bpm at 48 ± 6 h of life. RVO {mean (SD)} was 209.55(44.89) and 205.85(46.35) ml/kg/min, LVO {mean (SD)} was 133.68(31.15) and 134.78(29.84) ml/kg/min whereas SVC flow {mean (SD)} was 106.85(26.21) and 109.29(25.11) ml/kg/min at 12 ± 6 and 48 ± 6 h of life respectively. There was good intra-observer agreement in all the variables. SGA babies had a significantly higher heart rate at 12 ± 6 h of life as compared to AGA babies, although this difference in heart rate could not be appreciated at 48 ± 6 h of life. However SGA babies had a higher LVO, RVO and SVC flow than AGA babies at both the time points of observation.CONCLUSION: After DCC there is less fluctuation in the hemodynamic parameters (heart rate, cardiac output) at the two time points of observation.. As compared to AGA babies, SGA babies had a significantly higher baseline heart rate, LVO, RVO and SVC flow. LVO of SGA babies after delayed cord clamping is found to be significantly lower than LVO seen in other studies, favoring the cardio-stabilizing effect of DCC.BRIEF RATIONALE: This is the first study with a large sample size evaluating the hemodynamic effects of DCC in term neonates by functional echocardiography. The normative data of heart rate and cardiac output of term, stable babies with small for gestational age(SGA) as a special subgroup undergoing DCC requires further evaluation.PMID:35524194 | PMC:PMC9074198 | DOI:10.1186/s12887-022-03303-4…

  • Effect of Delayed Umbilical Cord Clamping on Hemodynamic Instability in Preterm Neonates below 35 Weeks

    J Trop Pediatr. 2022 Apr 5;68(3):fmac035. doi: 10.1093/tropej/fmac035.ABSTRACTINTRODUCTION: Delaying umbilical cord clamping facilitates postnatal transition in neonates but evidence on its effect in reducing hemodynamic instability in preterm neonates is inconclusive.AIMS: To evaluate delayed cord clamping (DCC) in reducing the incidence of hemodynamic instability in preterm neonates below 35 weeks gestational age admitted to the neonatal intensive care unit.METHODS: Neonates between 25 weeks and 34 weeks and 6 days gestation were enrolled. Hemodynamic and respiratory parameters were monitored over 48 h. Hemodynamic instability was defined as persistent tachycardia and/or hypotension necessitating therapy.RESULTS: The DCC cohort included 62 neonates with an equal number in the non-DCC group. The birth weight [mean ± standard deviation (SD)] was 1332.90 ± 390.05 g and the gestational age (mean ± SD) was 31.64 ± 2.52 weeks. Hemodynamic instability was noted in 18/62 (29%) neonates in the DCC cohort and 29/62 (46.7%) in the non-DCC group; relative risk (RR) 0.62 [95% confidence interval (CI) 0.38-0.99] (p = 0.023). The duration of inotrope requirement in the DCC cohort (mean ± SD) was 38.38 ± 16.99 h compared to 49.13 ± 22.90 h in the non-DCC cohort (p = 0.090). Significantly higher systolic, diastolic and mean arterial pressures were noted from 6 h to 48 h in the DCC cohort (p < 0.001). The severity of respiratory distress and FiO2 requirement was also less in the first 24 h. There was no difference in the incidence of patent ductus arteriosus, late-onset sepsis or mortality.CONCLUSION: Delaying umbilical cord clamping at birth by 60 s resulted in significantly lower hemodynamic instability in the first 48 h and higher blood pressure parameters.PMID:35512365 | DOI:10.1093/tropej/fmac035…

  • Cord clamping beyond 3 minutes: Neonatal short-term outcomes and maternal postpartum hemorrhage

    Birth. 2022 May 2. doi: 10.1111/birt.12645. Online ahead of print.ABSTRACTBACKGROUND: Delaying cord clamping (CC) for 3-5 minutes reduces iron deficiency and improves neurodevelopment. Data on the effects of CC beyond 3 minutes in relation to short-term neonatal outcomes and maternal risk of postpartum hemorrhage are scarce.METHODS: This was a prospective observational study performed in two delivery departments. Pregnant women with vaginal deliveries were included. Time to CC, estimated postpartum blood loss, and perinatal data were recorded. Spearman's correlation analysis and comparisons between newborns clamped before and after 3 minutes were performed.RESULTS: In total, 904 dyads were included. The mean gestational age ± standard deviation was 40.1 ± 1.2 weeks. CC was performed at a median time of 6 minutes (range 0-23.5). Apgar scores at 5 and 10 minutes were positively correlated with time to CC (correlation coefficient .140, P < .001 and .161, < .001). There was no correlation between CC time and bilirubin level (correlation coefficient .021, P = .54). The median postpartum blood loss was 300 mL (70-2550 mL), with a negative correlation between CC time and postpartum blood loss (-0.115, P = .001). The postpartum blood loss was larger in the group clamped at ≤3 minutes (median [interquartile range] 400 mL [300-600] vs 300 mL [250-450], [P = .003]].CONCLUSIONS: Umbilical CC times beyond 3 minutes in vaginal deliveries were not associated with negative short-term outcomes in newborns and were associated with a smaller maternal postpartum blood loss. Although CC time as long as 6 minutes could be considered as safe, further research is needed to decide the optimal timing.PMID:35502141 | DOI:10.1111/birt.12645…

  • Hemodynamic Quality Improvement Bundle to Reduce the Use of Inotropes in Extreme Preterm Neonates

    Paediatr Drugs. 2022 May;24(3):259-267. doi: 10.1007/s40272-022-00502-5. Epub 2022 Apr 26.ABSTRACTBACKGROUND: We evaluated the effect of the quality improvement (QI) bundle on the rate of inotrope use and associated morbidities.METHODS: We included inborn preterm neonates born at < 29 weeks admitted to level III NICU. We implemented a QI bundle focusing on the first 72 h from birth which included delayed cord clamping, avoidance of routine echocardiography, the addition of clinical criteria to the definition of hypotension, factoring iatrogenic causes of hypotension, and standardization of respiratory management. The rate of inotropes use was compared before and after implementing the care bundle. Incidence of cystic periventricular leukomalacia (cPVL) was used as a balancing measure.RESULTS: QI bundle implementation was associated with significant reduction in overall use of inotropes (24 vs 7%, p < 0.001), dopamine (18 vs 5%, p < 0.001), and dobutamine (17 vs 4%, p < 0.001). Rate of acute brain injury decreased significantly: acute brain injury of any grade (34 vs 20%, p < 0.001) and severe brain injury (15 vs 6%, p < 0.001). There was no difference in the incidence of cPVL (0.8 vs 1.4%, p = 0.66). Associations remained significant after adjusting for confounding factors.CONCLUSIONS: A quality improvement bundled approach resulted in a reduction in inotropes use and associated brain morbidities in premature babies.PMID:35469390 | DOI:10.1007/s40272-022-00502-5…

  • Making the Argument for Intact Cord Resuscitation: A Case Report and Discussion

    Children (Basel). 2022 Apr 6;9(4):517. doi: 10.3390/children9040517.ABSTRACTWe use a case of intact cord resuscitation to argue for the beneficial effects of an enhanced blood volume from placental transfusion for newborns needing resuscitation. We propose that intact cord resuscitation supports the process of physiologic neonatal transition, especially for many of those newborns appearing moribund. Transfer of the residual blood in the placenta provides the neonate with valuable access to otherwise lost blood volume while changing from placental respiration to breathing air. Our hypothesis is that the enhanced blood flow from placental transfusion initiates mechanical and chemical forces that directly, and indirectly through the vagus nerve, cause vasodilatation in the lung. Pulmonary vascular resistance is thereby reduced and facilitates the important increased entry of blood into the alveolar capillaries before breathing commences. In the presented case, enhanced perfusion to the brain by way of an intact cord likely led to regained consciousness, initiation of breathing, and return of tone and reflexes minutes after birth. Paramount to our hypothesis is the importance of keeping the umbilical cord circulation intact during the first several minutes of life to accommodate physiologic neonatal transition for all newborns and especially for those most compromised infants.PMID:35455560 | PMC:PMC9031173 | DOI:10.3390/children9040517…

Bivariate analysis, multivariate Poisson Regression model, and Kappa concordance test were performed.RESULTS: The percentage of late/optimal clamping observed was 53.7%. The associated factors were skin-to-skin contact in the delivery room (PR = 0.76; 0.61-0.95; p = 0.014), position of the newborn below the vaginal canal (PR = 2.6; CI95%: 1.66-4.07; p < 0.001), position of the newborn at the vaginal level (PR = 2.03; CI95%: 1.5-2.75; p < 0.001), and need for newborn resuscitation in the delivery room (PR = 1.42; CI95%; 1.16-1.73; p = 0.001). Kappa concordance level of the professionals, records compared to the observation was: nurse 0.47, obstetrician 0.59, and pediatrician 0.86.CONCLUSION: the identification of associated factors and the comparison between recording and observing the clamping time can help in the planning and implementation of improvements for adherence to good practices at birth.PMID:35348571 | DOI:10.1590/1980-220X-REEUSP-2021-0423…

  • Guideline No. 424: Umbilical Cord Management in Preterm and Term Infants

    J Obstet Gynaecol Can. 2022 Mar;44(3):313-322.e1. doi: 10.1016/j.jogc.2022.01.007.ABSTRACTOBJECTIVE: To assess the impact of deferred (delayed) cord clamping (DCC) and umbilical cord milking in singleton and twin gestations on maternal and infant mortality and morbidity.TARGET POPULATION: People who are pregnant with preterm or term singletons or twins.BENEFITS, HARMS, AND COSTS: In preterm singletons, DCC for (ideally) 60 to 120 seconds, but at least for 30 seconds, reduces infant risk of mortality and morbidity. DCC in preterm twins is associated with some benefits. In term singletons, DCC for 60 seconds improves hematological parameters. In very preterm infants, umbilical cord milking increases risk for intraventricular hemorrhage.EVIDENCE: Searches of Medline, PubMed, Embase, and the Cochrane Library from inception to March 2020 were undertaken using Medical Subject Heading (MeSH) terms and key words related to deferred cord clamping and umbilical cord milking. This document represents an abstraction of the evidence rather than a methodological review.VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations).INTENDED USERS: Maternity and newborn care providers.PMID:35300830 | DOI:10.1016/j.jogc.2022.01.007…

  • Practices and attitudes about delayed umbilical cord clamping for term infants: a descriptive survey among midwives

    J Obstet Gynaecol. 2022 Aug;42(6):1751-1758. doi: 10.1080/01443615.2022.2036964. Epub 2022 Mar 7.ABSTRACTThe aim of this study was to assess variations in midwives' practices of cord clamping (early versus delayed) and to identify factors potentially associated with delayed clamping. This was a descriptive cross-sectional survey by self-administered online questionnaire among French midwives working in delivery rooms from March to July 2018. We obtained complete responses from 350 midwives. Only 120 (34.3%) reported always or sometimes performing delayed cord clamping at one minute or more after birth. Delayed cord clamping was significantly associated with midwives' experience (adjusted OR 3.99; 95% confidence interval [CI] 2.10, 7.83 for experience >10 years), maternity unit written protocol (adjusted OR (aOR) 5.17; 95% CI 1.88, 16.00), knowledge of guidelines (aOR 3.33; 95% CI 1.98, 5.71) and neonatal care level 1 (aOR 2.95; 95% CI 1.53, 5.78).Impact StatementWhat is already know on this subject? Despite benefits and the safety of delayed cord clamping, many newborns likely had their umbilical cords clamped immediately after delivery as part of routine care or because providers were not convinced of the benefits of delayed clamping.What do the results of this study add? Most of the midwives surveyed did not systematically delay cord clamping. Individual and organisational factors were associated with adherence to guidelines regarding delayed cord clamping.What are the implications of these findings for clinical and/or further research? A protocol should be implemented in every maternity unit with information about the benefits and risks of delayed cord clamping to reduce variations in practice and improve the safety of care.PMID:35253590 | DOI:10.1080/01443615.2022.2036964…

  • Effect of later cord clamping on umbilical cord blood gas in term neonates of diabetic mothers: a randomized clinical trial

    BMC Pediatr. 2022 Mar 1;22(1):111. doi: 10.1186/s12887-022-03170-z.ABSTRACTOBJECTIVE: To evaluate the effect of later cord clamping (LCC) on umbilical arterial blood gas in neonates of diabetic mothers.METHODS: This prospective study included a group of 160 diabetic mothers (DM) whose neonates were randomized to immediate cord clamping (ICC) (≤ 15 s after birth) or LCC (≥ 30 s after birth), and a group of 208 non-diabetic mothers (NDM) whose neonates were randomized to ICC or LCC as a reference. Cord arterial pH, base excess (BE), bicarbonate (HCO3-), partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), lactate, hemoglobin, hematocrit and glucose were compared among groups.RESULTS: In neonates of DM, there was no significant difference in cord arterial pH between the ICC and LCC group. LCC of ≥ 30 s decreased umbilical arterial HCO3- and BE and increased lactate (ICC versus LCC, HCO3-: 24.3 (22.7, 25.8) versus 23.7 (22.3, 24.7) mmol/L, P = 0.01; BE: -2.70 (-4.80, -1.50) versus - 3.72 (-5.66, -2.36) mmol/L, P = 0.006; lactate: 2.1 (1.6, 3.7) versus 2.7 (2.1, 4.3) mmol/L, P = 0.005), without the alterations of pCO2, pO2, hemoglobin, hematocrit and glucose. Similar results were found in neonates of NDM (ICC versus LCC, HCO3-: 24.3 (23.1, 25.7) versus 23.5 (22.3, 24.8) mmol/L, P = 0.01; BE: -2.39 (-3.73, -1.51) versus - 3.40 (-4.73, -1.91) mmol/L, P = 0.001; lactate: 2.2 (1.9, 3.3) versus 2.5 (2.0, 4.3) mmol/L, P = 0.01), except for the higher level of hemoglobin in the LCC group. The majority of diabetic mothers (ICC: 92.0%; LCC: 91.8%) had good blood glucose control. No differences were observed in acid-base status and glucose between neonates of DM and neonates of NDM in both ICC and LCC, but hemoglobin and hematocrit were elevated after ICC in neonates of DM compared to neonates of NDM.CONCLUSIONS: Later cord clamping of ≥ 30 s resulted in a tendency towards metabolic acidosis of umbilical arterial blood in neonates of DM and NDM. Umbilical arterial blood gas parameters at birth were similar in neonates of DM and NDM.TRIAL REGISTRATION: ClinicalTrials.gov: NCT04369313 ; date of registration: 30/04/2020 (retrospectively registered).PMID:35232426 | PMC:PMC8886805 | DOI:10.1186/s12887-022-03170-z…

  • A Randomized Controlled Trial of a 30- versus a 120-Second Delay in Cord Clamping after Term Birth

    Am J Perinatol. 2022 Feb 15. doi: 10.1055/a-1772-4543. Online ahead of print.ABSTRACTOBJECTIVE: Delayed cord clamping (DCC) has been recently adopted in neonatal resuscitation. The immediate cardiac hemodynamic effects related to DCC more than 30 seconds was not studied. We aimed to study the effect of DCC at 120 seconds compared with 30 seconds on multiple hemodynamic variables in full-term infants using an electrical cardiometry (EC) device.STUDY DESIGN: Present study is a randomized clinical trial. The study was conducted with full-term infants who were delivered at the Obstetrics and Gynecology Department in Cairo University Hospital. Sixty-eight full term infants were successfully enrolled in this trial. Cardiac output (CO) and other hemodynamic parameters were evaluated in this study by EC device. Hemoglobin, glucose, and bilirubin concentrations were measured at 24 hours. Newborn infants were assigned randomly into group 1: DCC at 30 seconds, and group 2: DCC at 120 seconds, based on the time of cord clamping.RESULTS: Stroke volume (SV) (mL) and CO (L/min) were significantly higher in group 2 compared with group 1 at 5 minutes (6.71 vs. 5.35 and 1.09 vs. 0.75), 10 minutes (6.43 vs. 5.59 and 0.88 vs. 0.77), 15 minutes (6.45 vs. 5.60 and 0.89 vs. 0.76), and 24 hours (6.67 vs. 5.75 and 0.91vs. 0.81), respectively. Index of contractility (ICON; units) was significantly increased in group 2 at 5 minutes compared with group1 (114.2 vs. 83.8). Hematocrit (%) and total bilirubin concentrations (mg/dL) at 24 hours were significantly increased in group 2 compared with group 1 (51.5 vs. 40.5 and 3.8 vs. 2.9, respectively).CONCLUSION: Stroke volume and cardiac output are significantly higher in neonates with DCC at 120 seconds compared with 30 seconds that continues for the first 24 hours.KEY POINTS: · CO is significantly increased with DCC at 120 seconds.. · SV is significantly increased with DCC at 120 seconds.. · Such effects continued during the entire 24 hours of life in full-term infants..PMID:35170013 | DOI:10.1055/a-1772-4543…

  • Delayed cord clamping: Impact on fetal cord blood gas analysis

    Aust N Z J Obstet Gynaecol. 2022 Apr;62(2):328-331. doi: 10.1111/ajo.13488. Epub 2022 Feb 7.ABSTRACTBoth delayed cord clamping (DCC) and cord blood gas (CBG) analysis are recommended practices for preterm births. However, the compliance rates remain lower than expected, with a DCC rate of only 48.9% and CBG sampling of 66.6% in the preterm cohort. DCC was associated with a significant reduction in success rate of paired CBG analysis in both the term and preterm cohort of 8.3% and 7.7% respectively. Our study highlights the difficulty in achieving both recommendations.PMID:35129206 | PMC:PMC9304228 | DOI:10.1111/ajo.13488…

  • Toward greater nuance in delayed cord clamping

    Curr Opin Pediatr. 2022 Apr 1;34(2):170-177. doi: 10.1097/MOP.0000000000001117.ABSTRACTPURPOSE OF REVIEW: For over a decade, the International Liaison Committee on Resuscitation has recommended delayed cord clamping (DCC), but implementation has been variable due to lack of consensus on details of technique and concerns for risks in certain patient populations. This review summarizes recent literature on the benefits and risks of DCC in term and preterm infants and examines alternative approaches such as physiologic-based cord clamping or intact cord resuscitation (ICR) and umbilical cord milking (UCM).RECENT FINDINGS: DCC improves hemoglobin/hematocrit among term infants and may promote improved neurodevelopment. In preterms, DCC improves survival compared to early cord clamping; however, UCM has been associated with severe intraventricular hemorrhage in extremely preterm infants. Infants of COVID-19 positive mothers, growth-restricted babies, multiples, and some infants with cardiopulmonary anomalies can also benefit from DCC. Large randomized trials of ICR will clarify safety and benefits in nonvigorous neonates. These have the potential to dramatically change the sequence of events during neonatal resuscitation.SUMMARY: Umbilical cord management has moved beyond simple time-based comparisons to nuances of technique and application in vulnerable sub-populations. Ongoing research highlights the importance of an individualized approach that recognizes the physiologic equilibrium when ventilation is established before cord clamping.PMID:35125380 | PMC:PMC8893040 | DOI:10.1097/MOP.0000000000001117…

  • Physiology, Neonatal

    2022 Apr 28. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2022 Jan–.ABSTRACTThe neonatal period is the period of the most dramatic physiologic changes that occur during human life. While the respiratory and cardiovascular systems change immediately at birth, other organ systems evolve slowly with time until the transition from intrauterine to adult physiology is complete. The transitional period of the newborn is a critical time for humans to adapt to life outside the womb. There are distinct physiologic changes during this period, especially regarding the respiratory and cardiovascular systems. The loss of the low-pressure placenta and its ability to facilitate gas exchange, circulation, and waste management for the fetus creates a need for physiologic adaptation.Premature birth can significantly thwart these physiologic changes from occurring as they should. The endocrine system, specifically the release of cortisol via the hypothalamus, is responsible for lung maturation of the fetus and the neonate. There is a “cortisol surge” that begins with cortisol levels of 5 to 10 mcg/ml at 30 weeks gestational age, 20 mcg/ml at 36 weeks, 46 mcg/ml at 40 weeks, and 200mcg/ml during labor. Cortisol is responsible for lung maturation, thyroid hormone secretion, hepatic gluconeogenesis, catecholamine secretion, and the production of digestive enzymes. Mature thyroid function appears to help prepare the neonatal cardiovascular system and aid in the regulation of temperature. Following clamping of the umbilical cord and the first breath of life, arterial oxygen tension increases, and pulmonary vascular resistance decreases, facilitating gas exchange in the lungs. Subsequent pulmonary blood flow will cause an increase in left atrial pressure and a reduction in right atrial pressure. Changes in the PO2, PCO2, and pH are contributing factors to these physiologic changes in the newborn. Lung surfactant plays a critical role in these changes allowing the lungs to mature upon delivery. Remnants of fetal circulation (ductus arteriosus, foramen ovale, ductus venosus) will also gradually recede during this neonatal period, defined as up to 44 weeks postconceptual age.PMID:30969662 | Bookshelf:NBK539840…
