延迟脐带结扎对早产儿的影响

Effect of Delayed Umbilical Cord Ligation on Premature Infants

目的:探讨延迟脐带结扎对早产儿的影响。方法:选取2016年3月-2017年2月本院经阴道分娩的早产儿120例为研究对象,按照随机数字表法分为观察组和对照组,各60例。对照组采用常规脐带结扎(出生后10 s),观察组采用延迟脐带结扎(延迟至出生后2 min),均行常规护理。观察两组早产儿生后24 h内的血常规指标(Hb、RBC及HCT)、生后1周内额部黄疸峰值、早产儿并发症情况。结果:观察组Hb、RBC及HCT均高于对照组(P<0.05);两组均未见红细胞增多症;观察组新生儿败血症、新生儿坏死性小肠结肠炎及新生儿贫血的发生率均低于对照组,比较差异有统计学意义(P<0.05);两组额部皮测胆红素峰值、新生儿高胆红素血症的发生率比较,差异均无统计学意义(P>0.05)。结论:延迟断脐可成为一项减少早产儿并发症及改善预后的措施,值得在国内推广应用。

To investigate the effect of delayed umbilical cord ligation in premature infants.Method:A total of120premature infants delivered through vagina in our hospital from March2016to February2017were selected as the research objects.According to the random number table method,they were divided into observation group and control group,60cases in each group.The control group was treated with routine umbilical cord ligation(10seconds after birth),and observation group was treated with delayed umbilical cord ligation(at least2minutes after birth),they received routine nursing.The blood routine indexes(Hb,RBC and HCT)within24hours after birth,the peak value of frontal jaundice within1week after birth and the complications of premature infants were observed.Result:The levels of Hb,RBC and HCT in observation group were higher than those of control group(P<0.05),and there was no erythrocytosis in two groups.The incidence of neonatal septicemia,neonatal necrotizing enterocolitis and neonatal anemia in observation group were lower than those of control group,the differences were statistically significant(P<0.05).The incidence of neonate hyperbilirubinemia and the peak value of transcutaneous bilirubin were compared between two groups,the differences were not statistically significant(P>0.05).Conclusion:Delayed umbilical cord ligation can be a measure to reduce the complications and improve the prognosis of premature infants,and it is worth popularizing in China.
