延迟钳夹早产儿脐带对早产儿贫血程度的影响

目的探讨延迟钳夹早产儿脐带对早产儿贫血的影响。方法选取早产儿60例，按随机数字表法分为观察组和对照组各30例。对照组采取常规断脐，观察组在此基础上延迟90s（生后至少2min）断脐。观察血红蛋白（Hb）、网织红细胞（Ret）、红细胞比容（HCT）和血清铁（SI）变化及贫血发生率和输血率。结果对照组早产儿Hb、HCT和sI在生后第1、2、4、8周均明显低于观察组（均P〈0．05），对照组早产儿Ret在生后第2、4周时均明显高于观察组（均P〈0．05）；观察组6个月时贫血发生率（13．3％）和输血率（6．7％）均明显低于对照组（43．3％、33．3％）（均P〈0．01）。结论延迟钳夹早产儿脐带能明显增加早产儿红细胞和铁储备，减少贫血发生率及其导致的输血。值得临床推广应用。

Study on delayed umbilical cord damping in preterm children to relieve the degree of anemia in premature children

Objective To investigate the delayed umbilical cord clamping in preterm children of anemia in premature children.Methods 60 preterm children were randomly divided into study group and control group 30 patients in each group.The control group was taken regular off umbilical,the observation group delay 90s(after birth at least 2min) off umbilical.Results The Hb, HCT, and SI in the postnatal 1,2,4,8 weeks were significantly lower than the observation group, the difference was statistically significant (all P ＜ 0.05), and the control group after birth in preterm children Ret in the first week was significantly higher than 2,4 in the observation group, the difference was statistically significant(all P ＜ 0.05) ; The observation group at 6 months the incidence of anemia(13.3％) and transfusion rate(6.7％) were significantly lower than the control group(43.3％ ,33.3％) ,the difference was statistically significant(all P ＜0.01).Conclusion Delyed umbilical cord clamping in preterm children could increase the red blood cells and iron reserves in preterm children, reduce the incidence of anemia caused by blood transfusion, was worthy of clinical application.
