Although the ideal contraceptive has not been found, intrauterine contraceptive devices offer distinct advantages and provide adequate contraception. Unfortunately, they have side-effects, complications and failures. Their use is contraindicated in pregnancy, abnormalities of the uterine cavity, uterine hypoplasia, infection and abnormal uterine bleeding. Patients who have had an ectopic pregnancy, who are prone to endocarditis, who have allergies to copper, or who are taking anticoagulants also should not use IUCDs, Insertion is best performed during menstruation, and the patient should be seen in follow up to assess placement and any side-effects, including cramps, bleeding, vaginal discharge, or discomfort during intercourse. Pregnancy may occur when the IUCD is in place, and prompt diagnosis is mandatory. Depending on the type of IUCD used, replacement time varies from one to three years.
虽然尚未找到理想的避孕方法,但宫内节育器具有明显的优势,能提供充分的避孕效果。然而,它们也存在副作用、并发症和失败的风险。在怀孕、宫腔畸形、子宫发育不良、感染和异常子宫出血的情况下,不建议使用宫内节育器。曾有宫外孕史、易患心内膜炎、对铜过敏或正在服用抗凝剂的患者也不应使用宫内节育器。最好在月经期间进行插入操作,并在后续随访中观察其位置和任何副作用,如痉挛、出血、阴道分泌物或性交不适。宫内节育器放置期间可能会发生妊娠,必须进行及时诊断。根据使用的宫内节育器类型不同,更换时间从 1 年到 3 年不等。
