三种引产方式在中晚期妊娠引产中的应用效果分析

目的分析不同引产方式在中晚期妊娠引产中的应用效果。方法选择2011年1月~2012年12月本院妇产科收治的160例孕13~36周自愿终止妊娠的孕妇作为研究对象,根据孕周分为中期妊娠组（孕13~27周）85例、晚期妊娠组（28~36周）75例,两组患者中根据孕妇自身情况分别选择利凡诺羊膜腔内注射引产（A组）、水囊＋缩宫素静脉滴注引产（B组）、米非司酮配合利凡诺羊膜腔内注射引产（C组）。比较中晚期妊娠组中孕妇不同种引产方式的引产效果。结果 85例中期妊娠者中,C组的宫缩开始时间、产程时间、住院时间明显短于A、B组,住院费用明显低于A、B组,产后出血量明显少于A、B组,差异有统计学意义（P〈0.05）;75例晚期妊娠者中,B组的宫缩开始时间、产程时间、住院时间明显短于A、C组,住院费用明显低于A、C组,产后出血量明显少于A、C组,差异有统计学意义（P〈0.05）。结论中期妊娠者宜选择米非司酮配合利凡诺羊膜腔内注射引产方式,而晚期妊娠者宜选择水囊＋缩宫素静脉滴注引产方式,以期达到最佳引产效果。

Application effect of three kinds of induced labour mode in the induced labour during middle and late pregnancy

Objective To analyze the application effect of different abortion methods in induced labour mode in the induced labour during middle and late pregnancy. Methods 160 pregnant women with voluntary termination of pregnancy at 13-36 weeks of gestation treated in our hospital from January 2011 to December 2012 were selected as the study objectives. According to gestational age,the pregnant women were divided into the mid-pregnancy group（13-27 weeks gestation,n=85） and the late pregnancy group（28-36 weeks,n=75）,patients in the two groups were given the abortion rivanol amniotic injection（the group A）,the water sac＋oxytocin for intravenous induction（the group B）,mifepristone combined with rivanol intra amniotic injection induction（the group C）,the induced labour effect of different induced labour mode in the middle and late pregnancy group. Results 85 cases in the mid-pregnancy group,contractions start time,labor time,hospitalization time in the group C was significantly shorter than that in the group A and B,hospitalization cost in the group C was significantly lower than that in the group A and B,the amount of postpartum hemorrhage in the group C was significantly was fewer than that in the group A and B,and there was a statistical difference（P〈0.05）.75 cases in the late pregnancy,labor time,hospitalization time in the group B was significantly shorter than that in the group A and C,hospitalization cost in the group B was significantly lower than that in the group A and C,the amount of postpartum hemorrhage in the group B was significantly was fewer than that in the group A and C,and there was a statistical difference（P〈0.05）. Conclusion Mifepristone combined with rivanol intra amniotic injection induction is selected by the pregnant women in middle pregnancy,while the water sac＋oxytocin for intravenous induction in late pregnancy in order to achieve optimal induced labour effect.
