【摘要】目的：探讨甲氨蝶呤辅助米非司酮配伍米索前列醇终止早孕的临床效果。方法：将264例妊娠34~49天妇女随机分成观察组与对照组，对照组采用米非司酮配伍米索前列醇进行药物流产,观察组额外加用甲氨蝶呤辅助药物流产，对两组药物流产成功率、孕囊2小时内的排出率、阴道出血持续时间、尿HCG10天内转阴情况进行比较。结果：观察组药物流产成功率、孕囊2小时内的排出率优于对照组，差异有高度统计学意义 (P<0.01)；观察组阴道出血持续时间10天内干净与尿HCG10天内转阴发生率较对照组高，差异有统计学意义(P<0.05)；两组各种副反应发生率差异均无统计学意义(P>0.05)。结论：单次口服25mg甲氨喋呤片辅助早孕药物流产，可以明显提高流产成功率、缩短孕囊排出的时间，可以缩短阴道出血持续时间，药物副反应无明显增加。

【Abstract】Objective: To study clinical effects of Methotrexate auxiliary Mifepristone and misoprostol to terminate early pregnancy. Methods: 264 patients 34-49 days pregnant women were randomly divided into observation group and control group .The control group were treated with mifepristone and misoprostol for medical abortion, the observation group extra auxiliary medical abortion with methotrexate, the two group success rate of medical abortion, pregnancy sac discharge rate of 2 hours, the duration of vaginal bleeding, urinary HCG cloudy time were compared. Results: Success rate of medical abortion group, gestational sac within 2 hours of discharge rate of the observation group was better, the difference was highly statistically significant (P <0.01); Duration of vaginal bleeding clean within 10 days and negative within 10 days of urine HCG Incidence of the observation group was better, the difference was statistically significant (P <0.05); The incidence of adverse reactions of various groups were not significantly different (P> 0.05). Conclusion: Single oral dose of 25mg methotrexate tablets assisted pregnancy abortion, can significantly improve the success rate of miscarriage, gestational sac shorter discharge time, to shorten the duration of vaginal bleeding, no significant increase in drug reaction.

米非司酮配伍米索前列醇应用于终止≤49天的早期妊娠是医疗机构十分常用的非手术措施终止早孕的一种方法，流产效果肯定、痛苦小、安全、副反应少或反应轻，但由于药物流产过程用时较长，开始用药至孕囊排出大都需要3~4天，且需要妇女到医院留观数小时，与手术流产相比相对费时又不方便，且存在药物流产不全、出血时间长等不足。当前的无痛人流让女性尤为担心的流产疼痛得到了有效解决，加上医疗市场化等原因，更可观的经济效益，方便省时，以及担忧药物流产的副作用等原因，使无痛人流得到了广泛推广 ......
