目的:评价人工流产术后即时放置活性γ型IUD、TCu380AIUD的临床效果。方法:采用前瞻性、随机对比方法对100例健康已生育的早孕妇女,在人工流产术后即时放置活性γ型IUD50例(活性γ型IUD组)、TCu380A50例(TCu380A组),于放置后的1、3、6、12个月随访,以生命表法统计两种IUD的终止情况。结果:使用12个月时,活性γ型IUD、TCu380A的妊娠率均为0.01/100妇女;脱落率分别为6.0/100妇女、8.0/100妇女,两组比较差别无统计学意义(P>0.05)。结论:人工流产术后即时放置活性γ型IUD、TC380A避孕效果好,脱落率相对较低,续用率高,安全,可接受性强,值得推广应用。
Objective: To evaluate the clinical effect of active γ-type IUD and TCu380AIUD immediately after induced abortion. Methods: A prospective and randomized comparative study was performed on 100 healthy pregnant women with early pregnancy who were given active γ-IUD50 (active γ-IUD group) and TCu380A (TCu380A group) immediately after the abortion. After placement, 1,3,6,12 months follow-up, life table method statistics of the termination of two IUD. Results: The pregnancy rates of both active γ-type IUD and TCu380A were 0.01 / 100 women at 12 months. The rates of shedding were 6.0 / 100 women and 8.0 / 100 women respectively. There was no significant difference between the two groups (P> 0.05 ). CONCLUSION: The active γ-type IUD is placed immediately after induced abortion. TC380A has good contraceptive effect, relatively low exfoliation rate, high recovery rate, safety and acceptability. It is worth popularizing and applying.
