宫内节育器(IUD)是种放置位置在子宫腔内、应用较为广泛、长效避孕手段[1]。对比各种资料数据,显示金属环放置在人体内的时间可为10~15年;塑料环因弹力差、支撑力较小,导致易变形和脱落,因此塑料环在人体内的放置时间平均为5年左右[2]。作为植入性器械,节育器产生避孕效果的同时,也会出现与预期效果无关的不良事件,由于大部分妇女缺乏对宫内节育器放置所致不良事件的认识,欠缺应对不良事件的措施,笔者就宫内节育器放置所致不良事件及临床处理对策进行回顾性分析和总结,为安全及有效地临床使用宫内节育器提供 IUD is placed in the uterine cavity, the more widely used, long-term means of contraception [1]. Comparison of various data, the metal ring placed in the human body can be 10 to 15 years; plastic ring due to poor elasticity, the support force is small, resulting in easy deformation and fall, so the plastic ring in the human body to place an average of 5 years or so [2]. As implantable devices, IUDs produce contraceptive effects, but also appear to have adverse events unrelated to the expected results, because most women lack awareness of adverse events caused by placement of IUD, lack of measures to deal with adverse events, I retrospective analysis and summary of adverse events and clinical management of intrauterine device placement for the safe and effective clinical use of IUD
