摘要 目的:探索宫颈管内放置小剂量米索前列醇软化扩张宫颈的最佳时间。方法:将300例妊娠6~10周自愿行人工流产术者随机分为三组,每组研究对象宫颈管内均放置米索前列醇100μg,Ⅰ、Ⅱ、Ⅲ组分别于放药后1、、行23h人工流产术,并记录术前无阻力通过的最大hagers宫颈扩张器号数。结果:Ⅰ、、组宫颈软化扩张的总有效率分别ⅡⅢ为60%、和96%97%,Ⅰ组与Ⅱ、Ⅲ组比较有显著性差异(P<0.01),Ⅱ组与Ⅲ组相比较无显著性差异,(P>0.05),三组宫颈软化扩张的显效率分别为20%、76%、80%,Ⅰ组与Ⅱ、Ⅲ组比较有显著性差异(P<0.01),Ⅱ组与Ⅲ组相比较无显著性差异(P>0.05)。结论:宫颈管内放置米索前列醇100μg,2h即能有效地软化扩张宫颈,延长作用时间软化扩宫强度增加的不明显。
