1 056例皮下埋植避孕剂取出原因分析

目的：探讨皮下埋植避孕剂取出原因与取出年龄和放置时间的关系。方法：对1994年1月—2014年12月在本所门诊取出皮下埋植避孕剂的1 056例育龄妇女进行取出原因分析，比较不同取出年龄段及不同放置时间的因症取出原因的构成比。结果：1 056例皮下埋植避孕剂取出人群中，539例期满取出，395例因月经异常取出，97例因除月经外其他不适取出，23例因计划妊娠或改用其他避孕方法取出，2例在有效期内避孕失败取出。皮下埋植避孕剂取出原因构成比在不同取出年龄组中差异有统计学意义（P＜0.05），在不同放置时间组中差异无统计学意义（P＞0.05）；其中不同取出年龄和放置时间组中，月经异常和头痛、痤疮等其他症状的构成比差异均有统计学意义（P＜0.05），计划妊娠或改用其他避孕方法的构成比差异无统计学意义（P＞0.05）。结论：皮下埋植避孕剂是持久、高效、简便的避孕方法，月经异常和头痛、痤疮等症状是不同年龄段和放置时间皮下埋植避孕剂取出的主要原因。

Analysis of the Reasons of Norplant Removal in 1056 Cases

Objective：To explore the relationship between the Norplant removal and the placed age and time. Methods：The reasons for the Norplant removal, and the constituent ratios of the reasons to removed-age and to placed-time, were analyzed in 1 056 cases in our Institution from January 1994 to December 2014. Results： In those 1 056 cases of Norplant removal, 539 cases were due to expiration, 395 cases were due to abnormal uterine bleeding, 97 cases were due to other discomfort beside menstruation, 23 cases were due to planned pregnancy or switch to other contraception, and 2 cases were due to contraceptive failure. The constituent ratio of the removed reasons showed significant difference in the different removed-age groups （P＜0.05）, but did not show significant difference in the placed-time groups （P＞0.05）. The constituent ratios of abnormal uterine bleeding，headache，acne and other symptoms, showed statistical difference in the removal age and implant time groups （P＜0.05）, while those ratios did not show significant difference in the planned pregnancy or switch to other contraception groups （P＜0.05）. Conclusions： Norplant is a long-acting, simple and efficient contraceptive method. The abnormal uterine bleeding, headache, acne and other symptoms are the main reasons of Norplant removal in different age and implant time groups.
