摘要
目的评估依托孕烯单根皮下埋植剂(Implanon?)的避孕效果、月经模式的改变和对痛经的治疗效果。方法以接受依托孕烯单根皮下埋植剂避孕的妇女200例为研究对象,术后随访24个月,分析其避孕效果,痛经缓解程度,不良反应和继用率。结果术后24个月,190例受试者完成随访,随访率95%。随访期间,无1例受试者意外怀孕,避孕率100%。另外,61例埋植前有痛经的受试者,55例埋植后痛经得到缓解,缓解率为90.2%。主要不良反应为月经模式改变141例(74.2%),包括不规则阴道流血60例(31.6%)、闭经6例(3.2%),经期延长63例(33.2%)、月经频发41例(21.6%);月经稀发20例(10.5%)、经量减少66例(34.7%)、经量增加10例(5.3%)。其他不良反应还有体质量增加32例(16.8%),痤疮21例(11.1%),激素相关不良反应63例(33.2%)。随访期间,16例受试者,包括阴道不规则流血(10例)、闭经(6例)提前取出植入剂,继用率为91.6%。结论依托孕烯单根皮下埋植剂的避孕效果好,有效缓解痛经程度,安全可靠,继用率高,可在临床上推广应用。
