剖宫产断脐位置与新生儿血红蛋白的相关研究

目的：研究剖宫产80例新生儿的断脐位置与血红蛋白（Hb）之间的关系，从而降低新生儿贫血的发生率。方法：剖宫产胎儿娩出后立即断脐，实验组在靠近胎盘位置处断脐，保留脐带长度〉50cm，并将脐带高于胎儿进行顺时针或逆时针旋转，将脐静脉内的血液挤入胎儿体内；对照组则按常规方法断脐。结果：实验组新生儿出生后1h和24hHb和HCT均高于对照组（P〈0．05），差异具有统计学意义。而72h血清胆红素水平两组相近（P〉0．05）。结论：剖宫产时断脐位置靠近胎盘，并将脐静脉内的血液挤入胎儿体内，可有效提高新生儿体内Hb和HCT水平，降低新生儿贫血的发生。

A Study on the Position of Clamping Umbilical Cord and Neonatal Hemoglohin during Cesarean Section

Objective：To study the relationship on the position of umbilical cord clamping during cesarean section and neonatal hemoglobin and in order to reduce the incidence of anemia in neonate. Methods ：The umbilical cords of both groups were clamped immediately after birth. But the experimental group was clamped near the placenta, keep the length of umbilical cord over 50cm and clockwiseor counterclockwise rotated in order to make the residual blood flow into the infants, while the control groups was clamped by conventional method.Results ：Hemoglobin and hemat- ocrit of infants of experimental group at 1 h and 24h are higher than that of control group. The difference between them is statistically significant（P〈0.05）. The serum bilirubin at 72h between them are not significant statistically significant （P 〉0.05）. Conclusion：The method of umbilical cords clamping near the placenta and make the residual blood flow in- to the infants, which can improve Hb and HCT, reduce ;he incidence of anemia in infants.
