The timing of umbilical cord clamping at birth: physiological considerations
While it is now recognized that umbilical cord clamping (UCC) at birth is not necessarily an innocuous act, there is still much confusion concerning the potential benefits and harms of this common procedure. It is most commonly assumed that delaying UCC will automatically result in a time-dependent net placental-to-infant blood transfusion, irrespective of the infant's physiological state. Whet...
متن کاملA physiological approach to the timing of umbilical cord clamping at birth.
Umbilical cord clamping at birth has a major impact on an infant's cardiovascular system that varies in significance depending upon whether the infant has commenced breathing. As umbilical venous return is a major source of preload for the left ventricle during fetal life, recent experimental evidence has shown that clamping the umbilical cord severely limits cardiac venous return in the absenc...
متن کاملVentilation before Umbilical Cord Clamping Improves Physiological Transition at Birth or “Umbilical Cord Clamping before Ventilation is Established Destabilizes Physiological Transition at Birth”
Bhatt et al’s paper provides a good argument for ensuring that ventilation is established before clamping the umbilical cord (1). The possibility that very early clamping could explain the increased occurrence of intraventricular hemorrhage was proposed in 1988 by Hofmeyr (2) who showed that in human babies there was a marked rise in arterial pressure when the cord was clamped as late as 35 s a...
متن کاملVentilation before Umbilical Cord Clamping Improves the Physiological Transition at Birth
The transition from a fetus to a neonate at birth represents a critical phase in our life. Most infants make this transition without complications, but preterm infants usually require some form of assistance due to immature cardiopulmonary systems that predispose them to lifelong sequelae. As the incidence of preterm birth is increasing, there is now an urgent need for the development of manage...
متن کاملDelayed Umbilical Cord Clamping After Birth.
Delayed umbilical cord clamping appears to be beneficial for term and preterm infants. In term infants, delayed umbilical cord clamping increases hemoglobin levels at birth and improves iron stores in the first several months of life, which may have a favorable effect on developmental outcomes. There is a small increase in jaundice that requires phototherapy in this group of infants. Consequent...
