目的:探讨剖宫产后瘢痕子宫中期妊娠引产适宜方法。方法:选取2010年9月~2012年9月间来该院就诊要求终止妊娠,剖宫产后瘢痕子宫妇女115例,其中应用米非司酮结合依沙吖啶引产法的引产对象75例为A组;由于孕周较短,羊水过少导致依沙吖啶羊膜内部注射困难的引产对象应用米非司酮结合米索前列醇引产法40例为B组。对比两组的引产效果和安全性。结果:A组引产孕周明显长于B组,差异有统计学意义(P<0.05);两组引产成功率之间差异无统计学意义(P>0.05);B组研究对象总产程显著低于A组,差异有统计学意义(P<0.01);A组胎盘滞留率显著低于B组,差异有统计学意义(P<0.01)。结论:米非司酮结合米索前列醇虽然引产总产程较短,但安全性较差,对于可正常进行羊膜内部注射依沙吖啶的引产对象,仍应首选米非司酮结合依沙吖啶引产法。
Objective: To investigate the appropriate method of induction of labor after mid-term pregnancy of cesarean scar. Methods: From September 2010 to September 2012, 115 women with uterine scar after cesarean delivery were enrolled in this hospital. Among them, 75 cases were induced by mifepristone combined with ethacridine induction A group; due to shorter gestational age, oligohydramnios caused by intraspecific injection of amniotic membrane amniotic ectopic pregnancy induced by mifepristone combined with misoprostol induction of labor in 40 cases for the B group. The induction of labor and safety were compared between the two groups. Results: The gestational weeks in group A were significantly longer than those in group B (P <0.05). There was no significant difference between the two groups in the success rate of induction of labor (P> 0.05). The total birth length in study group B was significantly lower than that in group B The difference between the two groups was statistically significant (P <0.01). The retention rate of placenta in group A was significantly lower than that in group B (P <0.01). Conclusion: Mifepristone combined with misoprostol, although short-term labor induction of total labor, but less safe, for the normal intra-amniotic injection of methacetin induction of labor should be the first choice of mifepristone combined with acridine Induction of labor.
