摘　　要：对８４名月经规律的正常妇女在避孕失败或无保护性交后要求紧急避孕者，按本人意愿分为３组：Ａ组（ｎ＝２４）于性交次日开始服米非司酮２５ｍｇ／１２ｈ、２天，共１００ｍｇ；Ｂ组（ｎ＝３０）性交次晨服双炔失碳酯７．５ｍｇ，１２小时后再服７．５ｍｇ，以后每晚服７．５ｍｇ，连服１０天，共９０ｍｇ；Ｃ组（ｎ＝３０）于性交后１２０小时内放置宫内节育器（ＩＵＤ）Ｍｕｌｔｉｌｏａｄ（ＭＩ）Ｃｕ３７５。结果：Ａ及Ｃ组无一例妊娠，成功率１００％，Ｂ组妊娠２例，成功率９３％。主要的副反应是恶心、呕吐等胃肠反应，均在Ｂ组出现，而月经改变以Ｂ及Ｃ组为多见。认为，米非司酮的效果优于双炔失碳酯；ＩＵＤ在排除了生殖道感染的妇女中使用，能取得满意的效果。Objectives: To study the efficacy of mifepristone A nordrin and intrauterine device (IUD) used for emergency contraception.
