Emergency contraception (EC) refers to use of a drug or device as an emergency method to prevent pregnancy after unprotected intercourse. The first report of using the copper-intrauterine device (Cu-IUD) for EC was in 1976 by Dr Lippes. From 1979 t0 2011,there were 42 studies (7034subjects) published in English or Chinese, with a defined population of women who presented for EC and were provided with Cu-IUDs. The data collected from six countries identifies the use of eight different types of Cu-IUDs. The Cu-IUDs were inserted between two and ten or more days after intercourse; the majority of insertions (74%) occurred within 5 days of intercourse. The pregnancy rate among these studies (excluding one outlier) was 0.09%.
There has been very strong evidence to confirm that the Cu-IUD is a highly effective method of contraception,after unprotected intercourse. Because they are safe for the majority of women, highly effective, and cost-effective when left in place as ongoing contraception, whenever clinically feasible. It is highly accepted by both parous women and nulliparous women. Cu-IUDs should be included in the range of emergency contraception options offered to patients presenting after unprotected intercourse.
紧急避孕是指在无保护性生活后使用药物或器械作为一种应急方式来预防妊娠。最早关于使用含铜宫内节育器运用于紧急避孕的报道是LIPPES医生发布于1976年。
从1979年到2011年,有42项关于使用含铜宫内节育作为紧急避孕的研究(含7034实验对象)的结果发布。研究中,含铜宫内节育器分别在无保护性生活后2日、10日或更久的时间内被放植。这些调研结果显示妊娠发生率仅为0.09%。
这些证据有力的证明了含铜宫内节育器在无保护性生活后作为紧急避孕方式是非常有效的。含铜宫内节育器对于绝大多数女性来说都是非常安全高效的。无论是对于经产妇女还是未经产女性,适应度都是非常高的。含铜宫内节育器应该被普及为无保护性生活后紧急避孕的方式的选择中去。(欧洲避孕与生殖医学杂志 上海计划生育研究所,程利南)
