胚囊大小影响米非司酮联合米索前列醇抗早孕效果的超声观察

The Influence of the size of Embryo sac by Ultrasound Measurement on The Result of Termination Early pregnancy with Ru486 and Misoprosfol.

用B超连续观察米非司酮合并米索前列醇(简称米索)终止早孕过程中子宫和胚囊的变化。探讨了在月经周期不规律、胚胎发育与闭经天数不符的情况下胚囊大小对米非司酮合并米索抗早孕效果的影响。结果表明:胚囊平均直径【2.30cm时,完全流产率平均为92.21%;当≥2.31cm时平均为65.00%,组间有极显著性差异(P】0.01)。提示:胚囊大小影响米非司酮合并米索抗早孕的效果。

The changes of uterus and embryo sac was observe of in the course termination of early pregnancy with Ru486 and misoprostol with B ultrasound. The purpose is to investigate the influence of the size of embryo sac upon the result of termination early pregnancy with Ru486 and Misoprostol in cases with history of menstruae disorder and inconsistentcy between size of embryo sac and days of amenorrhea. The results showed that complete abortion occurred in 92.00%, when the average diameter of embryo sac was less than 2.30cm,(100% when it was 1.51-1.90 cm) The complete abortion rate was only 81.80% 2.3cm. There was no marked difference between two groups.(p>0.05). This result showed that the size of embryo sac influenced the effect of termination of early pregnacy with Ru486 and Misoprostol.
