目的 :评价TCu380A、TCu2 2 0C、MLCu375三种宫内节育器的有效性、副反应和可接受性。方法 :见中国计划生育学杂志“我国常用口服避孕药和宫内节育器系统评估的方法概述”(2 0 0 5年 1期 17页 )。结果 :TCu380AIUD妊娠率及脱落率均低于MLCu375IUD ,副作用发生率高于MLCu375IUD ,续用率等同或高于MLCu375IUD ,临床综合效能与MLCu375IUD相近 ;TCu380AIUD妊娠率低于TCu2 2 0CIUD ,脱落率及安全性与TCu2 2 0CIUD相似 ,放置满 5年后续用率高于TCu2 2 0CIUD ;MLCu375IUD妊娠率略低于TCu2 2 0CIUD ,脱落率低于或等同于TCu2 2 0CIUD ,二者的副反应发生率相似 ,临床综合效能优于TCu2 2 0CIUD。建议 :可以继续使用TCu380AIUD、MLCu375IUD和TCu2 2 0CIUD ,并且加大TCu380AIUD和MLCu375IUD的使用份额。在总体上应优先考虑提供铜表面积≥ 30 0mm2 的宫内节育器
Objective: To evaluate the efficacy, side effects and acceptability of three kinds of IUDs, TCu380A, TCu220C and MLCu375. Methods: See the Chinese Journal of Family Planning magazine “China commonly used oral contraceptives and intrauterine device evaluation of the method outlined” (2005 1 period 17 pages). Results: TCu380AIUD pregnancy rate and the rate of shedding were lower than MLCu375IUD, the incidence of side effects than MLCu375IUD, the same or higher than the rate of MLCu375IUD clinical efficacy and MLCu375IUD clinical similar efficacy; TCu380AIUD pregnancy rate was lower than TCu220CIUD, shedding rate and safety Similar to the TCu220CIUD, the follow-up rate after 5 years of placement was higher than that of TCu220CIUD; the pregnancy rate of MLCu375IUD was slightly lower than that of TCu220CIUD, the rate of exfoliation was lower than or equal to TCu220CIUD, the incidence of side effects was similar, The overall efficiency is better than TCu2 20CIUD. Recommendation: You can continue to use TCu380AIUD, MLCu375IUD and TCu220CIUD, and increase TCu380AIUD and MLCu375IUD share of use. In general, should give priority to provide copper surface area ≥ 30 0mm2 IUD
