目的:探讨延迟脐带结扎对新生儿缺铁性贫血及铁储备的影响。方法:按照随机数字表法将余姚市第二人民医院2015年1月—2016年6月180例足月分娩孕妇分组为对照组(新生儿娩出后于10s内结扎脐带)与观察组(新生儿娩出2min进行脐带结扎),各90例。抽取脐带血检测脐血血红蛋白(Hb)、红细胞压积(Hct);待新生儿回病房后,每天坚持检测其经皮胆红素值(TCB),并记录其光疗情况;待新生儿出生4周后检测其足跟血血红蛋白及红细胞压积等指标。结果:两组脐血Hb及Hct水平比较,P>0.05;观察组出生后4周足跟血Hb、Hct水平明显高于对照组,P<0.05;观察组贫血率明显低于对照组,P<0.05。两组新生儿TCB水平及光疗率比较,P>0.05。结论:阴道足月分娩产妇实施延迟脐带结扎可提高新生儿4周的血红蛋白及红细胞压积,预防新生儿贫血,且对新生儿胆红素及光疗无影响,因此延迟脐带结扎是安全可行性的。
Objective: To investigate the effect of delaying umbilical cord ligation on neonatal iron deficiency anemia and iron reserve. Methods: According to the random number table, 180 pregnant women of full-term delivery from January 2015 to June 2016 in Yuyao Second People’s Hospital were divided into control group (neonates ligation of umbilical cord within 10s after delivery) and observation group (neonatal Delivered 2min for umbilical cord ligation), 90 cases each. Umbilical cord blood was collected for cord blood hemoglobin (Hb), hematocrit (Hct); to be back to the ward after the newborn insist on testing its transcutaneous bilirubin value (TCB), and record the phototherapy situation; to be born 4 Week after testing heel hemoglobin and hematocrit and other indicators. Results: The levels of Hb and Hct in umbilical cord blood of two groups were compared, P> 0.05. Hb and Hct levels in heel blood of observation group were significantly higher than those in control group 4 weeks after birth, P <0.05; anemia in observation group was significantly lower than that in control group <0.05. Two groups of neonatal TCB levels and phototherapy rate comparison, P> 0.05. CONCLUSION: Delayed umbilical cord ligating in full-term vaginal delivery improves hemoglobin and hematocrit for 4 weeks in neonates, prevents neonatal anemia and has no effect on neonatal bilirubin and phototherapy. It is safe and feasible to delay umbilical cord ligation .
