摘要
设计了以不锈钢丝螺旋为T型骨架的IUD,嵌入硅橡胶消炎痛和纯铜丝。自1994年6～12月在4个点放置600例,观察24个序月。并以TCu220C600例做对照组,按3、6、12、24个月随访。24个月续用率分别为97.69％和93.97％。随意测量两组各20例放置前、后3、6、12个月的月经血量。带消炎痛者经血量基本不变。而对照组血量约增加1倍。此外。还随意抽样10～20例不同时期宫颈粘液中消炎痛及Cu含量。作者认为鲁T药铜IUD具有安全、高效、副反应小、经济、放取方便等优点,为目前较理想的含药含铜开放型IUD。
To know the cumulative successful rate of a new medicated copper T IUD. Methods A newly designed IUD is characterized by a T shaped stainless steel wire containing silicon rubber indomathacin (20mg) and copper wire (200m2). The effect of it has been observed by lifetable method for 24 months on 600 women with a control group of TCu220C. The amount of menstrual blood and of copper as well as in-domathacin was measured for 10-20 cases at will at intervals. Results;The cumulative successful rate of the new IUD for 24 months was 97. 69% .while that of the control group 93. 97%. The amount of menstrual blood was nearly the same as if no IUD inserted. That of the control group was distinctly increased. The copper and the in-domathacin could be detected even at the end of 24 months. Conclusion; This new IUD is an IUD of high successful rate,low menstrual blood loss, low pregnancy rate and low expulsion rate. It is save , easily put and taken off. It is cheap and lasting in use.
