目的:探讨终止妊娠26～34周的最佳方法。方法:将180例终止妊娠者随机分为两组:每组90例,A组采用米非司酮+催产素;B组采用利凡诺羊膜腔注射引产术。观察两组胎儿胎盘排出时间、腹痛持续时间及阴道出血量情况。结果:两组阴道出血量比较无统计学差异(P>0.05);两组胎儿胎盘排出时间及腹痛持续时间比较有统计学差异(P<0.01)。结论:妊娠26～34周行利凡诺羊膜腔注射引产术为一种快速、安全、经济、有效的方法。
Objective: To explore the best way to terminate pregnancy in 26 ~ 34 weeks. Methods: 180 cases of termination of pregnancy were randomly divided into two groups: 90 cases in each group, A group mifepristone + oxytocin; B group rivanol amniotic injection induced abortion. Two groups of fetal placenta discharge time, abdominal pain duration and vaginal bleeding were observed. Results: There was no significant difference in the amount of vaginal bleeding between the two groups (P> 0.05). There was a significant difference between the two groups in the placenta discharge time and the duration of abdominal pain (P <0.01). Conclusion: Intravenous injection of Rivhenol injection during 26 ~ 34 weeks gestation is a fast, safe, economical and effective method.
