寿命表法在放置IUD后随访中的运用

The application of Life table method in removal of IUD

目的应用寿命表法评价育龄妇女放置宫内节育器(intrauterine contraceptive device,IUD)后的长期续用趋势。方法对206例放置吉妮IUD的玉溪市红塔区内及非本辖区但长住本区的育龄妇女进行跟踪随访,用寿命表法分析吉妮IUD放置失败率。结果置器后3个月随访时不良反应主诉较多,9个月后明显减少,且症状减轻。18个月后症状逐渐消失。IUD的失败主要是在前12个月,因此,预防IUD失败的有效时间是放置后的12个月内。结论寿命表法客观准确地反映了整个随访期间不同时点的真实情况,对长期追踪的病例进行研究,是一种较为科学的统计方法,值得推广。
