Advances in research on the early and late effect of delayed umbilical cord clamping on neonatal

Abstract

Neonatal is separated from the maternal by clamping the umbilical cord after delivery.And traditionally, the clinical practice is clamping the umbilical cord immediately after delivery .With the futher study of optimal timing of umbilical cord clamping, the effect of delayed umbilical cord clamping attracts more and more attention.This paper discussed about the subject of the early and late effect of delayed umbilical cord clamping on neonatal.We found that a briefly delay in clamping the umbilical cord increased the placental transfusion and blood volume, decreased the prevalence of anemia, promoted the stability of circulation and internal environment, without adversely affecting health of neonatal.
