摘要
目的 通过阴道B超测量孕囊大小 ,判断孕龄 ,观察不同孕龄的流产效果。方法按阴道B超测定孕囊的结果及Rossavik等的孕龄计算公式 ,将要求药物流产者分为 2组。早早孕组 1 86例 ,孕龄 33~ 41d ,平均孕囊直径 <1 2mm ;早孕组 1 62例 ,孕龄 42~ 49d ,平均孕囊直径 1 2~ 1 9mm。两组均服用米非司酮及米索前列醇终止早孕 ,流产后复查B超 ,测子宫内膜厚度 ,离院后服用生化汤 2周。结果 早早孕组完全流产率 (94.62 % )明显高于早孕组 (87.65 % ) ,有显著性差异 (P <0 .0 5) ;早早孕组平均孕囊直径 [(7.61± 2 .31 )mm]明显小于早孕组 [(1 5 .83±1 .92 )mm] (P <0 .0 1 ) ;两组子宫内膜厚度比较有显著性差异 (P <0 .0 1 ) ;早孕组出血时间明显长于早早孕组 (P <0 .0 1 )。结论 行药物流产时应尽量选择孕龄≤ 41d ,阴道B超提示平均孕囊直径 <1 2mm的早孕者 ,可提高药物流产的成功率。
Objective It is to investigate the effect of medical aborting to different gestational ages which were estimated by measuring gestational sac through transvaginal ultrasonography.Methods According to the diameters of gestational sac measured by transvaginal ultrasonography and the formulas established by Rossavik, et al, the pregnant women who volunteered to take medical abortion were divided into two groups. 186 cases in earlier pregnant group, whose gestational ages ranged from 33 days to 41 days and mean sac diameter less than 12mm, and 162 cases in early pregnant group, whose gestational ages ranged from 42 days to 49 days and mean sac diameter ranged from 12mm to 19mm, all took Mifepristone and Misoprostol to stop early pregnancy. Then endometrial thickness of each case was checked with ultrasonography and each had been treated with Shenghua decoction for two weeks.Results The complete abortion rate of earlier pregnant group (94.62%) was obviously higher than that of early pregnant group (87.65%) ( P <0.05). Mean sac diameter of earlier pregnant group [(7.61±2.31)mm] was significantly minor than that of early pregnant group [(15.83±1.92)mm] ( P <0.01). Significant difference was found between endometrial thicknesses of two groups ( P <0.01). The time of vaginal bleeding after medical abortion in earlier pregnant group was shorter than that in early pregnant group ( P <0.01). Conclusion For medical abortion, the pregnancy of gestational ages should be less than 41 days and the mean sac diameter should be less than 12?mm, thus the efficacy can be increased.
