摘　　要：足月儿和早产儿的适宜脐带结扎时间是多年来的争议话题。目前,各个国家、地区在临床实践中脐带结扎时间不一,主要分为2种:即刻脐带结扎指胎儿娩出后15 s内结扎脐带;延迟脐带结扎指胎儿娩出后至少30 s或等待脐带搏动停止后结扎脐带。延迟脐带结扎可增加胎盘内储血向新生儿体内的输血量,近期可提高新生儿血红蛋白水平,减少新生儿脑室内出血及晚期脓毒症的发生,且不增加产后出血发生率,远期可增加铁储备,降低贫血发生率。Controversy has long existed about the optimal time to clamp and cut the umbilical cord for full-term and preterm infants. Policies for timing of cord clamping vary in different countries, with immediate cord clamping generally carried out in the first 15 seconds after birth, whereas delayed cord clamping usually involves clamping more than 30 seconds after the birth or when cord pulsation has ceased. Delayed cord clamping can increase the placental transfusion volume to infants, short term benefits associated with delayed cord clamping include increased hemoglobin level, prevention of intraventricular hemorrhage and late onset neonatal sepsis, without increasing the incidence of postpartum hemorrhage, long term benefits include increased iron storage and prevention of anemia in infancy.
