放置宫内节育器次数与结局的关系

The relation between the number of intrauterine device insertion and its termination

对2814例纺织女工宫内节育器(IUD)使用情况进行了调查。曾置二次或二次以上IUD者占1/4;多次置IUD者脱落率、带器妊娠率、意外妊娠率均显著比置IUD次数少者为高。分析各次置IUD的最终结局发现,脱落、带器妊娠、意外妊娠、因症取出、继续存放与置IUD次数并无明显关系,结果还显示:IUD某种结局对再次发生同样结局有明显影响。经对影响多次置RID因素的逐步回归分析,选出了除宫腔径线以外的8种主要因素。

In order to investigate the relation between the number of intrauterine device (IUD) insertion and its termination, 2814 femal textile workers using IUD were X-ray screened and interviewed. About one fourth of them had used IUD more than twice. The rates of expulsion, pregnancy, accidental pregnancy of the multi—time IUD users were higher than those who used IUD fewer times. The analysis of the ultimate termination of IUD insertionrevaled that there was no significant relation between the number of IUD insertion and expulsion, pregnancy, accidental pregnancy, removal for medical reasons and continual retention. The result also showed that a certain termination of IUD insertion might have an obvious influence on the recurrence of the same termination. By using the stepwise regression analysis of the factors influencing the multi-insertion of IUD, 8 main fctors were selected into the regression equation except the uterine cavity shape.
