本文对1978年1月至1980年4月同期放置带铜不锈钢环形宫内节育器1154例和不锈钢环形宫内节育器1298例进行定期随访,以比较临床效果。资料均满二年,按生命表统计临床效果,结果为:①粗累计带器妊娠率,带铜节育器为2.85/100妇女,明显低于不带铜金属单环7.90/100妇女(p<0.01)。②脱落率,带铜节育器为19.28/100妇女,高于不带铜的15.78/100妇女(p<0.05)。③因症取出率分别为8.74及7.60/100妇女(p>0.05),二组间无差异。④二年继续存放率分别为67.56/100妇女和67.71/100妇女(p>0.05),二组相似。带铜节育器带器妊娠率明显降低,且不明显增加因症取出率,建议扩大使用。对于带铜宫内节育器的脱落率稍高的缺点有待研究和改进。
In this paper, from January 1978 to April 1980 the same period with copper stainless steel ring IUD placed 1154 cases and stainless steel ring IUD 1298 cases were followed up regularly to compare the clinical effect. The data were all over two years, according to the life table statistics clinical results, the results are as follows: ① Rough cumulative pregnancy rate with a device, with a copper IUD 2.85 / 100 women, significantly lower than the 7.90 / 100 women without copper metal single ring (p < 0.01). ② The rate of exfoliation was 19.28 / 100 for women with IUDs, 15.78 / 100 for women without copper (p <0.05). ③ The rate of removing the disease was 8.74 and 7.60 / 100 respectively (p> 0.05), there was no difference between the two groups. ④ The two-year survival rates were 67.56 / 100 women and 67.71 / 100 women respectively (p> 0.05), and the two groups were similar. Pregnancy rate with copper IUD device significantly reduced, and did not significantly increase the rate of removal due to illness, it is recommended to expand the use of. For copper with IUD shedding rate slightly higher shortcomings need to be studied and improved.
