输卵管银夹绝育术效果与安全性的前瞻性流行病学调查

A prospective epidemiological study on the effect and safety of tubal sterilization with silver clip

对河北（Ａ夹）、湖南（Ｂ夹）、山东（Ｃ夹）３种银夹采用多中心前瞻性研究，于１９９０年９月～１９９２年１２月在山西、河南、河北、湖南及山东５省共３９３２人进行了为期一年的观察，随访率９９．９５％。结果表明，术后一年绝育有效率Ｐｅａｒｌ指数与寿命表法两种方法，Ａ夹分别为９８．７４％、９８．７５％；８夹为９９．５９％、９９．５２％；Ｃ夹为９９．２０％、９９．１３％。经χ２检验差异无显著性。副反应：术后一年自述症状以腰痛多见，月经量、月经周期改变次之，三者发生率分别为４．４５％、２．８０％及２．１１％。盆腔检查所见：宫体炎、附件炎仅占０．６６％，未发现其他器质性病变；并对影响效果及副反应的因素进行了分析。研究结果表明，输卵管银夹绝育术效率高，副反应少，简便易行，有普遍推广价值。
