BACKGROUND
Studies comparing immediate intrauterine device (IUD) insertion after first-trimester surgical abortion with interval insertion show similar efficacy and expulsion rates. However, women randomized to interval insertion of an IUD are less likely to return for device placement. An ideal time to insert intrauterine contraception may be the day a woman presents for verification of a completed medical abortion. We examined immediate insertion of IUDs after completed first-trimester medical abortion.
STUDY DESIGN
This is a prospective, observational clinical study to determine expulsion rates of intrauterine contraception placed immediately after confirmed, completed first-trimester medical abortion.
RESULTS
Of 118 subjects, 78 women had levonorgestrel IUDs placed, whereas 41 women received copper IUDs. Of 97 subjects who completed the study, there were 4 clinical expulsions (4.1%) during 3 months of follow-up. There were no diagnosed pelvic infections, pregnancies, or uterine perforations. The continuation rate at 3 months was 80%.
CONCLUSION
Intrauterine devices inserted at the time of completed, confirmed first-trimester medical abortion have low rates of expulsion.
背景
比较早期妊娠手术后即刻放置宫内节育器（IUD）与间隔放置的研究显示，两者具有相似的疗效和脱落率。然而，随机分配至间隔放置 IUD 的女性更不可能返回放置该节育器。宫内节育器的理想放置时间可能是女性在完成药物流产后前来确认时。我们研究了药物流产完成后即刻放置 IUD。
研究设计
这是一项前瞻性、观察性临床研究，旨在确定在确认完成早期妊娠药物流产后即刻放置宫内节育器的脱落率。
结果
在 118 名受试者中，78 名女性放置了左炔诺孕酮 IUD，41 名女性放置了铜 IUD。在完成研究的 97 名受试者中，在 3 个月的随访中有 4 例临床脱落（4.1%）。无诊断性盆腔感染、妊娠或子宫穿孔。3 个月时的续用率为 80%。
结论
在确认完成的早期妊娠药物流产时放置的宫内节育器脱落率较低。
