Abstract: ［Abstract］  Objective〖HTSS〗〓To investigate the effects of oxytocin combined with delayed cord clamping and early cutting umbilical cord on maternal and neonatal perinatal health and related complications.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Total of 210 cases of cesarean section and neonatal was performed. All these patients were randomly assigned to control group in which umbilical cords were early cut(ECC) and experimental group in which cut umbilical cord more later(DCC). Age, gestational weeks, birth weight, third labor time, postpartum hemorrhage, bleeding and neonatal Apgar score, the occurred rate of postpartum two weeks of neonatal jaundice and anemia were recorded and analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓Postpartum bleeding volume in DCC group was less, neonatal 2 weeks in peripheral blood hemoglobin was higher and anemia occurred was lower than that in the control group. The difference is significantly different(P＜005). There was no significant difference in general comparison， age, gestational age and birth weight of newborn(P＞005). The third production duration and Apgar score, umbilical cord blood hemoglobin comparison, the incidence of jaundice was not statistically different compare to the control group(P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The safety period of umbilical cord rupture was 90-120 s for the newborns. The proper delay of breaking the umbilical time and the use of oxytocin can shorten the third stage of labor and reduce the amount of postpartum hemorrhage. It will not increase or aggravate the jaundice of the newborn and reduce the occurrence of anemia.
