背景:裸铜结构宫内节育器在铜离子释放过程中含有大量氧化物,容易导致女性出现出血和疼痛等.而纳米铜/低密度聚乙烯复合材料宫内节育器则可以很好地解决以上弊端,有利于维持育龄妇女的生殖健康.目的:分析纳米铜/低密度聚乙烯复合材料宫内节育器对置器后子宫出血、疼痛的影响.方法:将 98 例自愿要求放置宫内节育器的女性随机均分为两组,观察组放置纳米铜/低密度聚乙烯宫内节育器,对照组放置铜T型220C宫内节育器.放置结束后随访12个月,观察两组不良事件发生情况,包括子宫出血和疼痛等.结果与结论:置器后随访12个月,观察组有1例出现子宫出血,2例患者出现疼痛现象,不良事件发生率为6%;对照组有5例出现子宫出血,8例出现疼痛,不良事件发生率为27%;两组不良事件发生率比较差异有显著性意义(P < 0.05).表明纳米铜/低密度聚乙烯复合材料宫内节育器可有效减少置器后子宫出血和疼痛的出现.%BACKGROUND:Intrauterine device made of bare copper can release a great amount of oxides that are easy to cause bleeding and pain in women. Nano copper/low-density polyethylene intrauterine device can wel solve the above drawbacks, which is conducive to the maintenance of the reproductive health of women of childbearing age. OBJECTIVE:To explore the effect of nano copper/low-density polyethylene intrauterine device on post-implantation uterine bleeding and pain. METHODS:A total of 98 voluntary women asking for intrauterine device insertion were selected and randomized into control group (n=49) with 220C (TCu220C) T type copper intrauterine device and observation group (n=49) with nano copper/low-density polyethylene intrauterine device. Al the women were folowed up for 12 months, and incidence of adverse events, including uterine bleeding and pain, was observed and compared between the two groups. RESULTS AND CONCLUSION: During the folow-up, there were one case of uterine bleeding and two cases of pain in the observation group and the incidence of adverse events was 6%; in the control group, there were five cases of uterine bleeding and eight cases of pain, and the incidence of adverse events was 27%. There was a significant difference in the incidence of adverse events between the two groups (P< 0.05). These findings indicate that the nano copper/low-density polyethylene intrauterine device can effectively reduce the occurrence of uterine bleeding and pain after implantation.
