摘　　要：目的观察紧急避孕4种不同方法的临床效果。方法对432例无保护性生活对象,自愿要求紧急避孕的妇女分成4组。Ⅰ米非司酮组112例;Ⅱ左炔诺孕酮片组104例;Ⅲ复方左炔诺孕酮组120例;Ⅳ放置T cu 220宫内节育器组96例。观察4组临床效果。结果服用左炔诺孕酮的有效率为69.98%,其余方法平均有效率为91.32%,,可能与样本量过小有关。放置活性IUD组的不良反应明显低于其他3组,服用复方左炔诺孕酮组的不良反应高于其他两组,比较差异无统计学意义(P>0.05)。结论 4种不同的紧急避孕方法对降低非意愿妊娠发生率和减少人工流产率均有较好的效果,临床值得推广。Objective To observe the clinical effect of four different approaches for emergency contraception. Methods 432 cases of women with unprotected intercourse were divided into four groups which voluntarily requested for emergency contraception. 112 cases of women in Group Ⅰ were given mifepristone; 104 cases of women in Group Ⅱ were given levonorgestrel;120 cases of women in Group Ⅲ were given compound levonorgestrel; 96 cases of women in Group Ⅳ were put T cu 220 intrauterine device. The clinical effect of four groups was observed. Results The effective rate for taking levonorgestrel was 69.98%, while the average effective rate of the other methods were 91.32%, perhaps they were related with the too small sample volume. The side reaction for putting the active IUD group was obviously lower than other three groups. The side reaction for taking compound levonorgestrel was higher than other two groups, the difference was not statistically significant（P〉0.05）. Conclusion Four different methods of emergency contraception to reduce unwanted pregnancies and reduce the incidence of abortion rates has a good effect, clinical worth promoting.
