目的:探讨放置金属单环、母体乐铜375环及TCu环妇女带器妊娠的有关因素,指导育龄妇女合理避孕。方法:对260例放置上述3种宫内节育器(IUD)妇女带器妊娠有关因素进行分析。结果:放置金属单环者带器妊娠比例明显高于放置母体乐铜375及TCu者;放置3种IUD妊娠者中50%以上有环移位;<35岁组带器妊娠比例明显高于≥35岁组;不同放置年限均可出现带器妊娠,且放置年限越长,带器妊娠比例越高。结论:在指导育龄妇女避孕时尽量选择活性IUD,定期检查环位,及时发现环移位,应根据不同IUD放置年限及时更换,同时提高操作人员技术水平,从而降低带器妊娠率。
OBJECTIVE: To explore the factors related to the pregnancy of women with single metal loop, mother metal loop 375 and TCu loop, and to guide women of childbearing age in reasonable contraception. Methods: 260 pregnant women who placed the above three kinds of intrauterine devices (IUD) pregnancy were analyzed. Results: The proportion of pregnancies in metal monocyclists was significantly higher than those in patients with lebronchial 375 and TCu, and more than 50% of the three IUD pregnancies had ring dislocations. The gestational age was significantly higher in patients younger than 35 years 35-year-old group; different placement years may appear with pregnancy device, and the longer placement, the higher the proportion of pregnancy with the device. CONCLUSION: As far as possible, IUD should be used to guide the contraception of women of childbearing age, and the ring position should be checked periodically to find out the ring displacement in time. It should be replaced in time according to different IUD placement years, meanwhile, the technical level of operators should be improved.
