目的 评价中晚期妊娠引产过程中使用气囊仿生助产的效果.方法 将气囊置于宫颈管内充气扩张宫颈,加用人工破膜、缩宫素静滴加强宫缩,促使胎儿排出,结束分娩.结果 使用气囊仿生助产观察组总产程明显缩短,两组比较有显著性差异（t=23.40,P〈0.05）,自气囊扩张至胎儿娩出最短时间为25分钟,最长为5.3小时,平均时间为2.1小时.两组产后出血率比较有显著性差异（χ2=33.52,P〈0.05）.结论 气囊仿生助产术可应用于中晚期妊娠引产,具有缩短产程、减少产后并发症,安全、有效的优点.
Objective To evaluate the effect of balloon bionic midwifery in induction of labor in middle and late pregnancy. Methods Balloon was placed inside the cervical canal and was inflated to distend cervix. At the same time artificial rupture of membrane and oxytocin was used to end delivery. Results The total stage of labor when applying balloon bionic midwifery was obviously shortened, and the difference was significant （ t = 23.40,P 〈 0.05 ）. The shortest period from balloon expansion to baby delivered was 25 minutes, and the longest one was 5.3 hours, with average period of 2.1 hours. The difference in rate of postpartum hemorrhage of two groups was significant （X2 = 33.52, P 〈 0.05. ） Conclusion Being safe and effective, balloon bionic midwifery can be applied in induction of labor in middle and late pregnancy, and it can shorten delivery process and reduce complications.
