In the last decade, several studies have pointed out the importance of the correct timing
of umbilical cord clamping. Placental transfusion is an efficient way to increase
the volume of circulating blood, haematocrit, blood oxygen saturation, and optimise
postnatal adaptation of the cardiovascular system with the start of spontaneous
ventilation. There are accepted recommendations for umbilical cord clamping in
term newborns. However, as for preterm, or asphyxiated newborns that require resuscitation,
the information regarding the correct timing of placental transfusion,
the overall pathophysiology of postnatal adaptation is still unclear, as well as the details
on the mechanic and technical aspects of delayed cord clamping after spontaneous
births and C-sections. In situations where time is vital, manual milking of the
umbilical cord is a suitable alternative. Excluding the increased risk of requiring
phototherapy, the effects of placental transfusion on the newborn are positive. This
review aims to bring these positive effects to attention, and show that delayed cord
clamping should be a part of the routine practice during birth.
