将正常足月妊娠阴道分娩、非高危妊娠的 2 0 0例 ,随机分为两组 ,观察米索前列醇或缩宫素对产后 2 h内出血量的影响。实验组 12 0例 ,于胎头着冠时立刻口服米索前列醇 2片 (40 0μg) ;对照组 80例 ,胎儿娩出后立刻肌肉注射缩宫素 10 U。结果 :实验组第三产程平均时间较对照组缩短 5 .31min(P<0 .0 1) ,产后 2 h内平均出血量较对照组减少 118.8ml(P<0 .0 1)。提示米索前列醇具有比缩宫素更强的宫缩作用
Two hundred and ten cases of normal full-term pregnancy vaginal delivery and non-high risk pregnancy were randomly divided into two groups to observe the impact of misoprostol or oxytocin on the amount of bleeding within 2 h postpartum. Experimental group of 120 cases, immediately in the fetal head crown of misoprostol 2 (40 0μg); control group of 80 cases, the fetus immediately after delivery of oxytocin 10 U. Results: The mean duration of the third stage of labor was shortened by 5.31min (P <0.01) in the experimental group and 118.8ml (P <0.01) lower than that in the control group within 2 hours after delivery. Tip misoprostol has more contractions than oxytocin
