目的:探讨剖宫产术后早孕妇女行人工流产术前阴道放置米索前列醇对宫颈的扩张作用。方法:将自愿终止妊娠具有剖宫产史的早孕妇女100例随机分为两组,研究组于术前2h阴道放置米索前列醇0.2 mg,对照组不用任何药物。术中观察扩宫的难易程度,记录出血量、手术持续时间及手术并发症情况。结果:研究组术中无阻力扩宫的例数明显多于对照组(P<0.01),手术时间明显缩短、出血量明显减少、手术并发症明显减少(P<0.05)。结论:剖宫产术后早孕妇女行人工流产术前阴道放置米索前列醇可以有效扩张宫颈,缩短手术时间,减少术中出血,有效预防手术并发症。
Objective: To investigate the effect of vaginal misoprostol on cervical dilatation before induced abortion in women of early pregnancy after cesarean section. Methods: 100 pregnant women with history of cesarean section who voluntarily terminated pregnancy were randomly divided into two groups. The study group received misoprostol 0.2 mg vaginally in the study group without any drug. Intraoperative observation of the difficulty of expanding the Palace, recording the amount of bleeding, duration of surgery and surgical complications. Results: In the study group, there were more cases of no-resistance dilation than those in the control group (P <0.01). The operation time was significantly shortened, the amount of bleeding was significantly reduced, and the complications were significantly decreased (P <0.05). Conclusions: Misoprostol vaginal placement of misoprostol before induced abortion in early pregnant women after cesarean section can effectively expand the cervix, shorten the operation time, reduce intraoperative bleeding and prevent operative complications effectively.
