进入90年代后,惰性宫内节育器(IUD)已被活性含铜IUD所取代,目前在江苏省采用的品种不下10余种。虽然含铜IUD已被反复证明安全高效,但在普遍推广应用之后进一步的研究和指导仍十分必要,特别是在农村产后放置IUD的避孕效果对该地区的人口控制影响很大。为此,我们选择了较为常用的TCu380A、母体乐(ML Cu375)、研制中的三球头TCu370和含消炎痛γCu200随机用于江苏农村产后42天～6个月内的妇女,旨在对它们的避孕效果和副作用进行比较和评价。
Into the 90’s, IUD inert IUD has been replaced by the activity of copper IUD, currently used in Jiangsu Province, no less than 10 varieties. Although copper-containing IUDs have been repeatedly proven to be safe and effective, further research and guidance are still necessary after the universal application. In particular, the contraceptive effect of IUD placement in rural areas has a great impact on population control in the area. To this end, we chose the more commonly used TCu380A, MLR375, MLB330, TCu370 under development and indomethacin γCu200 were randomly used in Jiangsu rural postpartum 42 days to 6 months of women, aimed at them Contraceptive effects and side effects were compared and evaluated.
