Latest research on cord clamping

BLog & News

We will continously blog on our own and others results on cord clamping, as well as other news related to the subject, such as umbilical cord milking and resuscitation.

In memory of Hans Rosling:

Curiosity. Commitment. Factfullness.
On three occasions, Hans tweeted about our research. Obviously, I was both surprised and proud that this occupied and certainly hard courted person had time to follow what we've done. Now he is deceased, lost to all of us, but especially of course for his family, friends and loved ones.
There are many who have shared their memory of Hans Rosling during the recent days, yet I cannot help but share my thoughts with you.
We are many who admire Hans and what he accomplished, from his many years of work as a doctor in Africa, his research and start-up of programs in global health and his work with Gapminder. His humanism. In all I think three words shines brightly:
Curiosity. Commitment. Factfullness.
Hans always seemed to be curious, to phenomena in the world around us, curious on people, to figure out how the earth can be better place to live. The altruistic commitment he radiated, the commitment to spread knowledge, to help people, the passion to reach out, not to gain personal benefit, but for everyone's best. And then the word that Hans is said to have coined, and he was writing a book about: factfulness. To see past our own beliefs and prejudices. The ability to see the reality that is in front of us and to base our arguments on facts and not something else.
This last has never been so important as today, when many of us so easily begin to listen to the populists and the prophets of doom, the Trumps and right extremes.
Others have written that Hans Rosling's voice was more important now than ever before. I guess what we really should say is that everyone's vote is more important than in a long time.
When similar winds as from before World War II blows cold all around us, then it is time to join Hans Rosling disciples to become apostles: Start with a good dose of humanism and add thereto Curiosity. Commitment. And perhaps above all Factfulness.
Thanks for all Hans. I will try my best to honor your memory.

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."

    Am J Physiol Regul Integr Comp Physiol. 2019 06 01;316(6):R716-R724
    Authors: Smolich JJ, Kenna KR, Mynard JP
    Abstract
    The glucocorticosteroid betamethasone is routinely administered via maternal intramuscular injection to enhance fetal lung maturation before anticipated preterm birth. Although antenatal betamethasone increases fetal pulmonary arterial (PA) blood flow, whether this agent alters the contribution of 1) right ventricular (RV) output or 2) left-to-right shunting across the ductus arteriosus to rises in PA blood flow after preterm birth is unknown. To address this question, anesthetized control (n = 7) and betamethasone-treated (n = 7) preterm fetal lambs (gestation 127 ± 1 days, means ± SD) were instrumented with aortic, pulmonary, and left atrial catheters as well as ductus arteriosus and left PA flow probes to calculate RV output, with hemodynamics measured for 30 min after cord clamping and mechanical ventilation. Mean PA blood flow was higher in betamethasone-treated than in control lambs over the initial 10 min after birth (P < 0.05). This higher PA flow was accompanied by 1) a greater pulmonary vascular conductance (P ≤ 0.025), 2) a larger proportion of RV output passing to lungs (P ≤ 0.01), despite a fall in this output, and 3) earlier reversal and a greater magnitude (P ≤ 0.025) of net ductal shunting, due to the combination of higher left-to-right (P ≤ 0.025) and lesser right-to-left phasic shunting (P ≤ 0.025). These results suggest that antenatal betamethasone augments the initial rise in PA blood flow after birth in preterm lambs, with this augmented rise supported by the combination of 1) a greater redistribution of RV output toward the lungs and 2) a faster and larger reversal in net ductal shunting underpinned not only by greater left-to-right, but also by lesser right-to-left phasic shunting.
