结扎脐带是由胎儿转变为新生儿的里程碑式标志,然而,对于结扎脐带的时机选择迄今尚存争议。目前尚无结扎脐带的统一标准,大多数临床医师均采用新生儿生后立即进行早期结扎脐带(ECC)的方法。但越来越多的研究结果显示,延迟结扎脐带(DCC)在增加新生儿有效循环血容量、增加铁储备、减少新生儿贫血、增强免疫能力等方面具有不可忽视的作用。现笔者拟就近年来DCC对新生儿及婴儿影响的相关研究进行综述如下。
Ligation of the umbilical cord is a milestone for the conversion of the fetus to a newborn, however, the timing of ligation of the umbilical cord has so far been controversial. There is no uniform standard for ligation of the umbilical cord, and most clinicians use the method of early ligation of the umbilical cord (ECC) immediately after birth. However, more and more studies show that delayed ligating of umbilical cord (DCC) plays an important role in increasing newborn blood volume, increasing iron reserve, reducing neonatal anemia and enhancing immunity. Now I intend to DCC in recent years, the impact of neonatal and infant studies are summarized below.
