药物与人工流产妇女术后感染率的比较

Incidence of postoperative infections between women undergoing medical abortion and women undergoing artificial abortion

目的比较分析药物流产与人工流产妇女术后生殖道感染的发生率。方法选择停经49d内要求人工终止妊娠且无相应禁忌证的562名初孕孕妇,根据本人意愿选择终止妊娠方法,随机分为药物流产组308名和人工流产术组254名,观察比较两组流产后生殖道感染的发生率。结果药物流产组308名中有3名流产后发生生殖道感染,感染率0.97%,人工流产术组254名中有6名发生生殖道感染,感染率2.36%,两组比较差异有统计学意义(P<0.05)。结论药物流产宫腔内没有手术操作,子宫内膜不会形成人为的局部创面,减少了感染的机会,从而流产后生殖道感染率更低。

OBJECTIVE To compare and analyze the incidence of postoperative reproductive tract infections in women undergoing medical abortion and women undergoing artificial abortion. METHODS Totally 562 primigravid pregnant women with 49d menopause, who required termination of pregnancy without corresponding contraindications, were enrolled in the study and divided into the medical abortion group with 308 subjects and the artificial abortion group with 254 subjects according to the personnel willingness, then the incidence of reproductive tract infections after the abortion was observed and compared between the two groups. RESULTS In the medical abortion group, the reproductive tract infections occurred in 3 of 308 women in the medical abortion group with the infection rate of 0.97% and in 6 of 254 women in the artificial abortion group with the infection rate of 2. 36%, the difference between the two groups was statistically significant（P〈0. 05）. CONCLUSION The medical abortion, without being performed operation procedure in uterine cavity, may not lead to a man-made local injury of endometrium, which reduces the risk of being infected, thus the incidence of reproductive tract infections is ever lower.
