目的:探讨延迟断脐对婴幼儿贫血的影响及其安全性。方法:将2011年2月至2011年8月在珠海市人民医院足月阴道分娩孕产妇160例按入院单、双日随机分为快速断脐组(n=76)和慢速断脐带组(n=84),快速断脐组在胎儿娩出后5-10 s内断脐,慢速断脐带组在胎儿娩出后2 min断脐,比较两组新生儿胆红素峰值、达峰时间及血红蛋白浓度和血细胞比容。结果:两组新生儿胆红素峰值、达峰时间均无明显差异(P>0.05),而慢速断脐带组新生儿血红蛋白浓度在生后3天及6个月时均显著高于快速断脐组(P<0.05)。结论:慢速断脐在延迟2 min的可控时间内,不提高新生儿胆红素峰值及达峰时间,但可提高新生儿的血容量,增加血红蛋白浓度和血细胞比容,减少缺铁性贫血的发生,且可延续到6个月时。
Objective: To investigate the effect and the safety of delayed umbilical cord on infant anemia. Methods: From February 2011 to August 2011, 160 pregnant women of full-term vaginal delivery in Zhuhai People’s Hospital were admitted to hospital on the basis of single admission, and were randomly divided into two groups: the fast broken umbilicus group (n = 76) and the slow broken umbilical cord group n = 84). In the rapid umbilicus group, the umbilical cord was cut off within 5-10 seconds after the fetus was delivered, and the umbilical cord was cut off at 2 minutes after the umbilical cord was delivered. The bilirubin peak, peak time and hemoglobin Concentration and hematocrit. Results: There was no significant difference in neonatal bilirubin peak and peak time between the two groups (P> 0.05), while the neonatal hemoglobin concentration in the neonatal umbilical cord group was significantly higher than that of the fasting cord blood at 3 and 6 months after birth Umbilical group (P <0.05). CONCLUSION: The slow umbilical cord does not increase the peak time and peak time of neonatal bilirubin within the controlled time of 2 min, but it can increase the blood volume of newborn, increase the hemoglobin concentration and hematocrit, and reduce the iron deficiency Anemia occurs, and can be extended to 6 months.
