目的探讨缩宫素在胎儿前肩娩出后静脉滴注与肌肉注射预防产后出血的疗效分析。方法分析分娩800例孕妇中随机分为研究组400例(其中自然分娩200例,剖宫产200例),在胎儿前肩娩出后静脉滴注缩宫素预防产后出血。对照组400例(其中自然分娩200例,剖宫产200例),在胎儿前肩娩出后于子宫肌层或臀部肌内注射缩宫素预防出血。结果研究组的产后出血率1.25,对照组产后出血率10.5,两组经统计学处理(P<0.01)差异有统计学意义。结论胎儿前肩娩出后静脉滴注缩宫素比肌内注射缩富素能有效持久地帮助子宫收缩,减少宫腔积血,预防产后出血。
Objective To investigate the curative effect of oxytocin on preventing postpartum hemorrhage by intravenous infusion and intramuscular injection after anterior fetal shoulder delivery. Methods Analysis of delivery of 800 pregnant women were randomly divided into study group 400 cases (of which 200 cases of natural childbirth, 200 cases of cesarean section), in the anterior shoulder after delivery of oxytocin intravenous injection to prevent postpartum hemorrhage. Control group of 400 cases (including 200 cases of natural childbirth, 200 cases of cesarean section), in the anterior fetal shoulder after delivery in the myometrium or the buttocks intramuscular injection of oxytocin to prevent bleeding. Results The postpartum hemorrhage rate in the study group was 1.25 and the postpartum hemorrhage rate in the control group was 10.5. The difference between the two groups was statistically significant (P <0.01). Conclusions Intrauterine injection of oxytocin after intrauterine injection of oxytocin can help uterine contraction effectively and persistently and reduce uterine hemorrhage and prevent postpartum hemorrhage.
