Abstract: Objective　To evaluate the effect of delayed ligature of the umbilical cord on he blood inculcation of neonates via caesarean section in early time. Methods　From July 2007 to September 2009，137 newborns in Department of Neonatology，Dongguan Shilong Boai Hospital were randomly divided into routine ligature of the umbilical cord group （71 cases） and delayed ligature umbilical group （66 cases）； comparison was made on delayed ligature time， blood routine examination at 48 h after birth ，hemobilirubin and anemia incidence 3 days after birth. Results　There was significant difference between the 2 groups in delayed ligature time， blood routine examination at 48 h after birth ，and the incidence rate of anemia， which was decreased significantly in delayed ligature umbilical group （P < 0.05）. Conclusion　Delayed ligature of umbilical cord has a significant influence on hemoglobin and hematocrit of newborn via caesarean section in early time， and it can reduce the incidence of anemia.

摘要： 目的　探讨延迟钳夹脐带对剖宫产新生儿早期血液灌输的影响。方法　2007年7月至2009年9月东莞石龙博爱医院产科经剖宫产分娩的137例新生儿随机分成两组，即常规钳夹脐带组（71例）和延迟钳夹脐带组（66例）。比较分析两组剖宫产新生儿的钳夹脐带时间、生后48 h血常规及生后3d内静脉血胆红素值和贫血的发生率。结果　两组剖宫产新生儿钳夹脐带时间、生后48 h内血常规指标及贫血发生率的比较差异有统计学意义（P < 0.05），延迟钳夹脐带组贫血发生率减少。结论　延迟钳夹脐带对剖宫产新生儿早期血红蛋白（Hb）、红细胞压积（HCT）有显著影响，可减少剖宫产新生儿早期贫血的发生率。
