目的:探讨阴道后穹窿放置米索前列醇对绝经后的宫颈软化、宫颈扩张、吸刮取出宫内节育器。方法:选择2010年1月—2012年12月在我中心门诊要求取宫内节育器而无禁忌证的绝经后妇女80例,随机分为两组:观察组40例,对照组40例,观察组术前3小时阴道后穹窿部内置米索前列醇400μg;对照组常规取宫内节育器,观察两组宫颈扩张情况、疼痛程度、取器时间、出血情况及后果。结果:观察组有效率为95.0%,对照组有效率为70.0%,两组总有效率比较有显著差异性(P<0.05)。结论:绝经后宫内节育器取出术前3小时阴道后穹窿置米索前列醇400μg能有效软化宫颈,缩短手术时间,减少术中出血量,提高取器成功率。
Objective: To investigate vaginal posterior fornix placed misoprostol on postmenopausal cervical softening, cervical dilatation, suction to remove the IUD. Methods: From January 2010 to December 2012, 80 cases of postmenopausal women without IUD in our center were randomly divided into two groups: observation group (40 cases) and control group (40 cases) Three hours before operation, the vaginal fornix was filled with 400 μg of misoprostol. The control group was given IUD. The cervical dilatation, pain, time, bleeding and consequences of the two groups were observed. Results: The effective rate was 95.0% in the observation group and 70.0% in the control group. The total effective rate in the two groups was significantly different (P <0.05). CONCLUSION: Taking 400 μg of misoprostol into the vaginal posterior fornice after 3 hours of preoperative IUD retrieval can effectively soften the cervix, shorten the operation time, reduce the intraoperative blood loss and improve the success rate of the device.
