目的探讨腹部彩超引导下可视人工流产术前应用米索前列醇扩张宫颈的效果。方法选取2013年就诊大田县妇幼保健院门诊,经超声诊断为宫内早孕拟行人工流产术的早孕者274例,随机分为3组,分别在术前2h经不同途径给予米索前列醇1片(200μg)扩张宫颈,A组舌下含服,B组阴道后穹窿放置,C组口服。观察各组的宫颈扩张效果、术前阴道出血量、用药后副作用和术中腹痛情况。结果 3种给药方式的宫颈松弛软化程度比较,A、B、C组有效率分别为85.9%、64.8%和57.4%,A组有效率较高;3组术前阴道出血量均较少;A组副作用较少。结论米索前列醇含服扩张宫颈效果较好、作用快。彩超引导下可视人流术提高了人流术的准确性和安全性,降低了手术风险,能减少患者痛苦和并发症发生。
Objective To investigate the effect of misoprostol dilation of cervix before visual guided abortion guided by abdominal ultrasonography. Methods A total of 274 pregnant women who were admitted to the MCH hospital in Datian County in 2013 were diagnosed as intrauterine early pregnancy by artificial abortion. They were randomly divided into 3 groups. The patients were given misoprostol 1 (200μg) to expand the cervix, sublingual group A sublingual, B group vaginal posterior fornix, C group oral. The effects of cervical dilatation, preoperative vaginal bleeding, side effects after medication and intraoperative abdominal pain were observed. Results Compared with the control group, the effective rates of cervical relaxation and softening in groups A, B and C were 85.9%, 64.8% and 57.4%, respectively. The effective rate of group A was higher. A group of side effects less. Conclusion Misoprostol dilatation of the cervix is better and faster. Color Doppler guided visualization improves the accuracy and safety of abortion, reduces the risk of surgery, and reduces patient pain and complications.
