摘要
目的:评价新型宫内节育器(IUD)GyneFix IUD和MCu IUD及传统节育器TCu220IUD的避孕效果。方法:以人工流产术后志愿放置IUD的690例为对象,随机分为3组,分别于人工流产术后即时放置Gyne Fix IUD、MCu IUD和TCu220IUD。结果:GyneFix IUD,MCu IUD和TCu220IUD使用12个月带器妊娠率分别为0.48%、0.85%、3.75%,脱落率分别为0.93%、0.85%、2.92%,因症取出率分别为2.80%、3.81%、6.25%,续用率分别为95.80%,94.49%,87.08%,放置IUD后月经异常发生率分别为8.88%、5.93%、12.5%。结论:GyneFix IUD、MCu IUD和TCu220IUD避孕效果均较理想,但TCu220IUD可能是放置型号不易掌握,带器妊娠、脱落、月经异常发生率较两种新型IUD高。
Objective: To evaluate the contraceptive effects of three new types of IUDs ( Gynefix, MCu and TCu220). Methods: 690 volunteers who underwent induced abortion at Hangzhou technical service center for family planning during 2003 were randomly divided into three groups which had 214 persons, 236 persons and 240 persons and received inserting of Gynefix, Mcu or TCu220 IUD, respectively, immediately after induced abortion. Results: The contraceptive effects of three IUDs were good with few pregnancies because of expulsion. The pregnancy rates with IUD were 0.48% , 0.85% and 3.75% , respectively. Expulsion rates were 0.93% , 0.85% and 2.92% , respectively. Removal rates because of side - effect were 2. 80% , 3.81% and 6.25 % , respectively. Continuation rates were 95.80% ,94.49% and 87.08 % , respectively. Abnormal menstruation rates with IUD were 8.88 % , 5.93% and 12.5 % , respectively. Conculsion: The contraceptive effects of three new types of IUDs (Gynefix, MCu and TCu220) are ideal besides the pregnancy rate, expulsion rate and abnormal menstruation rate with TCu220 are higher than those of the other two IUD which maybe due to the difficulty in choosing different TCu220 sizes.
