孕晚期三种引产方法的临床观察

Clinical observation on three induced-labor methods for late pregnancy

目的探讨孕晚期的三种引产方法的安全性和有效性。方法将有引产指征的孕足月的初产妇随机分为三组:米索前列醇组、蓖麻油煎鸡蛋组、低浓度缩宫素组各50例,分别使用米索前列醇、蓖麻油煎鸡蛋、低浓度缩宫素三种方法引产。结果米索前列醇组和蓖麻油煎鸡蛋组引产不但有效率高于低浓度缩宫素组,而且剖宫产率也低于低浓度缩宫素组,用药至临产时间短于缩宫素组,产后出血量也以缩宫素组多,三组新生儿窒息率无差异。结论小剂量米索前列醇多次阴道给药及口服蓖麻油煎鸡蛋用于足月妊娠引产是一种安全、方便、有效的引产方法,但使用时须严密观察。

Objective To study the clinical effect and safety of three induced - labor methods applied in late pregnancy. Methods One hundred and fifty pregnant women without constriction were randomly devided into 3 groups：administrated misoprostol as group A,castor bean oiled egg as group B, and oxytocin as group C. Results The effective rates of induced labor of group A and group B were significantly higher than that of group C ;the rates of cesarean section and the bleeding volume after labet of group A and group B were significantly lower than that of group C ;the parturient onset time of group A and group B were shorter than that of group C. Among those groups,there was no significant difference in neonatorum asphyxia. Conclusion Putting a less dose of misoprostol into vagina repeatedly and taking the fried egg in castor bean oil are safe, convenient and effective methods in induction of late pregnancy, but it should be noticed strictly during induced labor using misoprostol.
