使用Norplant皮下埋植剂阴道流血模型分析

上海医科大学妇产科医院自1984年引进Norplant,进行"中国妇女对Norplant可接受性研究"共观察1657例,木文对开始使用的548例对象的月经卡进行分析,目的是观察使用 Norplnt皮下埋植剂对象的阴道流血变化规律。结果显示使用 Norplant避孕的妇女阴道流血总和（包括滴血、流血和严重流血）的平均天数和滴血天数,在第1个90天的参考时限中分别为33．0天和21．5天;在第4个参考时限中分别为26．7和13．8天;到第20个参考时限分别降低至20．2和9．5天。闭经者在各个不同的参考时限分别占0．5～5．4％。结论是使用Norplant皮下埋植剂的妇女,总和的阴道流血天数随着使用时间的延长而逐渐减少。主要是"滴血"天数减少,而"流血"和"严重流血"的天数变化不大。
