对 40 9例孕 13～ 2 7周口服米非司酮片配伍米索前列醇片引产的孕妇进行观察 ,48例病人出血量较多。对出血原因进行统计学分析 ,结果显示 :孕周越小不全流产发生率越高 ,P <0 .0 5。孕 13～ 2 0周引产出血的主要原因是不全流产 ,其次为宫缩乏力 ;孕 2 1～ 2 7周引产出血的主要原因是不全性流产和软产道损伤 ,其次 ,为宫缩乏力 ;孕周越大 ,软产道损伤发生率越高 ,P <0 .0 5 ;各孕周出血发生率比较无显著差异P >0 .0 5。提出预防和治疗出血的关键措施是密切观察病情变化 ,准确判断出血原因并及时去除 ,同时做好抢救工作 ,加强心理护理 ,认真做好健康教育
Forty-nine pregnant women who were given mifepristone tablets and misoprostol tablets during 13 to 27 weeks of gestation were observed. 48 patients had more bleeding. Statistical analysis of the causes of bleeding, the results showed: the smaller the gestational age, the higher the incidence of incomplete abortion, P <0. Pregnancy 13 ~ 20 weeks the main reason for bleeding induced by abortion is incomplete abortion, followed by uterine inertia; pregnancy 21 to 27 weeks of induction of bleeding is mainly due to incomplete abortion and soft birth canal injury, followed by uterine atony; pregnancy The larger the week, the higher the incidence of soft birth canal injury, P <0. 05; the incidence of bleeding in each gestational week was no significant difference P> 0. Proposed prevention and treatment of bleeding is the key measure to closely observe the changes in condition, accurately determine the cause of bleeding and timely removal, while doing a good job of rescue work, strengthen psychological care, do a good job of health education
