摘要
目的：探讨左炔诺孕酮宫内缓释系统（LNG-IUS）分别于人工流产后即刻、经期、经后放置的临床效果.方法：202例妇女分别在人工流产后即刻、经期1～7d、经后3～7d放置LNG-IfS,随访12个月,对其避孕效果、副反应、因症取出和续用率进行观察比较.结果：随访12个月3组均无妊娠和IUS脱落,续用率＞92/百妇女年,3组差异无统计学意义（P＞0.05）;经期延长和不规则点滴出血为主要副反应,影响满意度和续用率.放置后6个月内人工流产组较早出现闭经,经期延长和不规则点滴出血发生率较经期组和经后组低（P＜0.01）,经期组与经后组差异无统计学意义（P＞0.05）,至放置后12个月经期延长和不规则点滴出血发生率均明显下降,3组无统计学差异（P＞0.05）.结论：放置LNG-IUS是安全可靠的长效避孕方法,人工流产后即刻、经期、经后3～7d均为适宜的放置时机,而即刻放置出血副反应少,满意度高,依从性好.
Objective：To compare clinical effects of levonorgestrel-releasing intrauterine system （LNG-IUS） inserted immediately after induced abortion,during menstruation and after the menstrual period.Methods：Two hundred and two women were divided into 3 groups.Women in group Ⅰ underwent LNG-IUS insertion immediately after surgical abortion in group Ⅰ,during the menstrual period in group Ⅱ,and on 3-7 days after the menstruation in group Ⅲ.All the women were followed up for 12 months.The contraceptive effectiveness,side effects,removal rate for medical reasons and continuation rate were evaluated.Results：During 12 months of follow up,no pregnancy and LNG-IUS expulsion were found.The continuation rate was more than 92/100 women per year,and no statistical differences were found among 3 groups （P＞0.05）.The major side effects were menostaxis and irregular spotting,which influenced the satisfaction and continuation rates.Within 6 months,Women in group Ⅰ experienced menorrhea earlier,and menostaxis and vaginal irregular bleeding was less than those of the other two groups,showing statistical differences（P ＜0.01）.While there were no significant differences in the incidence rates of menostaxis and vaginal irregular bleeding between group Ⅱ and group Ⅲ （9＞0.05）.The incidence rates of menostaxis and vaginal irregular bleeding declined obviously close to a year later,and no statistical differences were found among the three groups （P＞0.05）.Conclusion：LNG-IUS is considered to be a safe and reliable long-term contraceptive method due to a higher satisfaction and better compliance.It is suggested to insert LNG-IUS immediately after surgical abortion,during the menstrual period,and on 3 -7 days after the menstruation.
