目的探讨不同的断脐方法对阴道分娩的新生儿血红蛋白及血清胆红素水平的影响。方法收集经阴道足月自然分娩的104例单胎新生儿的临床资料。根据断脐方式的不同,将入选新生儿分成观察组(50例)和对照组(54例)。比较两组的一般资料、生后5 d内的血清胆红素水平、出生时与生后3 d的红细胞压积和血红蛋白水平。结果两组新生儿生后5 d内血清胆红素水平与达高峰时间均无统计学意义(P>0.05)。观察组新生儿出生时及生后3 d的红细胞压积及血红蛋白值均显著高于对照组(P<0.01)。结论经阴道自然分娩的新生儿采用30 s内靠近胎盘端的断脐法较常规断脐法更为合理,不但不会增加新生儿黄疸的发生风险,还能适当增加新生儿的血红蛋白及血容量,值得临床推广。
Objective To investigate the effect of different broken umbilical cord on neonatal hemoglobin and serum bilirubin in vaginal delivery. Methods The clinical data of 104 singleton neonates with vaginal full-term spontaneous delivery were collected. According to the way of breaking the umbilical cord, the selected newborn were divided into observation group (50 cases) and control group (54 cases). The general data of two groups were compared, serum bilirubin levels within 5 days after birth, hematocrit and hemoglobin levels at birth and 3 days after birth. Results There was no significant difference in serum bilirubin level and peak time between the two groups in 5 days after birth (P> 0.05). The hematocrit and hemoglobin of newborns in observation group at 3 d after birth and after birth were significantly higher than those in control group (P <0.01). Conclusion Neonatal vaginal delivery through the placenta end of the 30s off the umbilical cord method than the normal off the umbilical cord method is more reasonable, not only does not increase the risk of neonatal jaundice, but also an appropriate increase in neonatal hemoglobin and blood volume, Worth clinical promotion.
