摘　　要：目的对药物流产失败的相关因素进行调查和分析,旨在为提高药物流产的成功率提供进一步的指导依据。方法对我所诊治的1 800例行药物流产的患者根据年龄、孕龄、孕囊直径、子宫位置、有无剖宫产史进行分组比较各组的流产失败率。结果本组入选的1 800例药物流产患者中,发生药物流产失败者共142例,流产失败率为7.89%。其中年龄≥35岁,孕龄>42 d,孕囊直径≥20 mm,子宫处于后倾、前倾及后屈位以及有剖宫产史组患者的流产失败率明显高于相应的对照指标组(P<0.05)。结论重视孕妇的年龄、孕龄、既往分娩方式、子宫位置、孕囊大小等相关影响药物流产失败的因素,才更有利于降低药物流产的失败率。Objective To survey and analyze the relevant factors of the failure of medical abortion.
