目的探讨不同剂量的米索前列醇扩张宫颈的疗效。方法 67例患者随机分为 A、B两组。A组 3 5例 ,给予米索前列醇 2 0 0 μg阴道后穹窿内置入 ,B组 3 2例 ,米索前列醇 40 0 μg阴道后穹窿内置入。结果用药后两组宫颈口扩张显著者 60例 ( 89.5 5 % ) ,有效者 5例( 7.46% ) ,无效 2例。B组宫颈扩张度和宫颈扩张≥ 8mm的百分率明显高于 A组 ,术中平均出血量明显低于 A组。结论人工流产术前 3小时阴道后穹窿内放置米索前列醇 40 0 μg是极好的辅佐方法。
Objective To investigate the effect of different doses of misoprostol on cervical dilatation. Methods 67 patients were randomly divided into A and B groups. A group of 35 patients were given misoprostol 200 Gy intravaginal implants, B group of 32 patients, misoprostol 40 0 ug into the vaginal fornix. Results After dosing, there were 60 cases (89.5%) in which the cervix was dilated significantly, 5 cases (7.46%) were effective and 2 cases were ineffective. In group B, the percentage of cervical dilatation and cervical dilatation≥8mm was significantly higher than that in group A, and the mean intraoperative bleeding was significantly lower than that in group A. Conclusion Misoprostol 40 0 μg in vaginal posterior fornixes three hours before induced abortion is an excellent adjuvant method.
