目的探讨MCuⅡ功能性宫内节育器(intrauterine contraceptive device,IUD)的临床使用效果。方法随机放置MCuⅡIUD、MCu IUD各100例,置器后第1、3、6、12个月随访,填写统一记录。结果观察12个月两组累计带器妊娠率分别为0、1.0%;累计脱落率均为0;医疗原因(出血和疼痛)取出率分别为3.0%、2.0%。不良反应发生率随放置时间延长而减少,12个月随访时分别为3.2%、3.3%。结论两种IUD带器妊娠率、脱落率、不良反应发生率均低,取出更容易,值得推广。
Objective To investigate the clinical effect of intrauterine contraceptive device (MCI). Methods Randomly placed MCu Ⅱ IUD, MCu IUD each 100 cases, followed by 1, 3, 6, 12 months follow-up, fill in a unified record. Results The cumulative pregnancy rates of the two groups were 0 and 1.0% respectively at 12 months. The cumulative rates of exfoliation were 0. The removal rates of medical causes (bleeding and pain) were 3.0% and 2.0% respectively. The incidence of adverse reactions decreased with the placement of time, 12 months follow-up were 3.2%, 3.3%. Conclusion The pregnancy rate, exfoliation rate and incidence of adverse reactions in both IUD devices are both lower and easier to remove, which is worth to be popularized.
