目的：比较胎儿娩出后2~3 min 与30 s 内结扎脐带对缺铁性贫血及铁储备的影响。方法选取产科分娩新生儿361例为研究对象，依照胎儿娩出结扎脐带时间分为晚结扎组181例和早结扎组180例，晚结扎组胎儿娩出后2~3 min 结扎脐带，早结扎组胎儿娩出后30 s 内结扎脐带，分析两组新生儿铁储备以及缺血性贫血情况。结果出生3天晚结扎组血红蛋白（Hb）（186.25±15.26）g / L、血细胞比容（ Hct）（0.54±0.03）%，显著高于早结扎组（165.26±16.82，0.51±0.05）（ P 0.05）。4月龄晚结扎组和早结扎组红细胞平均体积（ MCV）差异无显著性（ P >0.05）；晚结扎组血清铁蛋白（SF）水平（52.75±0.73）g/ L 显著高于早结扎组（27.59±1.26）g/ L，P 0.05），晚结扎组 SF 水平低于早结扎组，但差异无显著性（ P >0.05）。两组患者产后大出血发生率、新生儿红细胞增多症发生率以及新生儿光疗比率差异无显著性（ P >0.05）；但晚结扎组高胆红素血症发生率（18.8%）显著低于早结扎组（38.3%，P 0. 05). The difference in level of MCV in neonates at age of 4 months was not statistically significant between these two groups ( P > 0. 05). The difference in levels of serum ferritin(SF)( P 0. 05),the level of SF in later ligation group was lower than that of early ligation group,but the difference was not statistically significant( P > 0. 05). The incidence rate of postpartum hemorrhage and the increase of count of red blood cells in neonates were not significantly different between these two groups( P > 0. 05). The incidence of hyperbilirubinemia(18. 8 % )in neonates of later ligation group was significantly lower than that(38. 3% )of neonates in early ligation group( P < 0. 05). Conclusion The delayed ligation of umbilical cord in neonates can raise the iron reservation and reduce the incidence of iron deficiency anemia,and it is beneficial for the growth and develop-ment of neonates.
