目的探讨药物流产不全及失败的相关因素。方法回顾我院2898例经米非司酮配伍米索前列醇终止妊娠的临床资料,分析药物流产不全及失败的相关因素。结果孕周>7周者药物流产不全及失败率高于孕周≤7周者,差异有统计学意义(P<0.01);经孕者药物流产不全及失败率高于初孕者,差异有统计学意义(P<0.01);孕囊直径≥20 cm者药物流产不全及失败率高于孕囊直径<20 cm者,差异有统计学意义;后倾后屈位置子宫药物流产不全及失败率高于前倾水平位置子宫,差异有统计学意义(P<0.01)。结论药物流产不全及失败率与孕周、孕次、孕囊大小、子宫位置有关。
Objective To investigate the related factors of incomplete medical abortion and failure. Methods The clinical data of 2898 cases of termination of pregnancy with mifepristone and misoprostol in our hospital were retrospectively analyzed, and the related factors of incomplete medical abortion and failure were analyzed. Results Weeks> 7 weeks of medical abortion and failure rate was higher than those of gestational weeks ≤ 7 weeks, the difference was statistically significant (P <0.01); pregnancy drug abortion and failure rate was higher than the first pregnancy, the difference was Statistical significance (P <0.01); gestational sac diameter ≥ 20 cm were incomplete medical abortion and failure rate was higher than that of gestational sac diameter <20 cm, the difference was statistically significant; posterior retroversion uterine bleeding incomplete abortion and failure rate The uterus was higher than the anterior levinal level, the difference was statistically significant (P <0.01). Conclusion Medical abortion and failure rate and gestational age, gestational age, gestational sac size, the location of the uterus.
