产妇产时及产后24小时内失血量观察

A STUDY ON THE AMOUNT OF BLEEDING OF PARTURINT AT DELIVERY AND IN 24 HOURS

目的 了解我院产妇分娩 2 4小时内真实失血量 ,观察测量了 10 0例产妇胎盘娩出前 ,接产结束 ,结束后 2小时 ,2— 2 4小时内 4个阶段失血量 ,并与目测组相比较。方法 采用容积法、称重法 ,辅以部分面积法。结果 产后出血率为 40 % ,剖宫产与阴道产 2 4小时内失血量比较差异无显著性 ,产时失血量比较有显著差异(P <0 .0 5 ) ,产后出血者血色素及红细胞产前与产后 3天相比较有非常显著差异 (P <0 .0 1) ,红细胞压积比较亦有显著差异 (P <0 .0 5 ) ;产后出血者 97.5 %血压在正常范围。目测组产后出血率为 11% ,与观测组比较有显著差异(P <0 .0 1)。目测组产后 2小时内失量仅为观测组的 70 %。结论 准确测量产后失血量 ,有助于预防及处理产后出血。

To determine the amount of bleeding of parturint in 24 hours affer delivery,the amount of bleeding was investigated in 100 cases in antenatal of plecenta,postnatal,in 2 hours and 2～24 hours respectively,which measured by the methods of Volume,weigh in balance and area accurately,it campared with visual estimation group. The redults showed that the bleeding rate of more than 500ml was 40% and it compared with 11% in visual group,there were significant difference(P<0.05).The amount of bleeding in 24 hours after labour were no differece (P>0.05) compared with hysterotokotomy and veginal labour,there were significant difference(P<0.05) in labour stage. It suggests that the amount of bleeding of partarint affer labour should be measured accurately in order to prevent and manage the postpartum hemorrhage.
