目的:观察第三代“爱母”牌宫内节育器(MYCu IUD)在人工流产术后即时放置的临床效果和安全性。方法:通过前瞻性随机对照研究,对932例研究对象于人工流产术后即时放置MYCu IUD(研究组)、T形含铜IUD(TCu380A)(对照组),每组各466例,放置后1个月、3个月、6个月、12个月定期随访。结果:930例完成了12个月的随访,失访2例;无子宫穿孔、带器妊娠发生;无其他医疗原因或个人原因取器者;置器12个月时研究组与对照组随访率均为99.8%;置器1年净累积续用率研究组(96.14%)高于对照组(88.41%)(P<0.05);置器后1个月、3个月、6个月、12个月研究组与对照组累积脱落率相似,差异无统计学意义(P>0.05);置器后1个月、3个月、6个月因症取出率研究组均显著低于对照组,每次随访差异均有统计学意义(P<0.05);置器后1个月IUD嵌顿发生率研究组明显高于对照组(P<0.05);置器后1个月、3个月、6个月与IUD使用相关的终止率研究组均明显低于对照组(P<0.05);置器后1个月、3个月、6个月副反应发生率研究组均明显低于对照组(P<0.05)。结论:人工流产术后即时放置MYCu IUD、TCu380A的避孕效果均良好,虽然MYCu IUD因症取出率、副反应发生率低于TCu380A,但其嵌顿发生率高于TCu380A。
Objective: To observe the clinical effect and safety of the third generation MYCU IUD after artificial abortion. Methods: By prospective randomized controlled study, MYCu IUD (study group) and T-shaped copper-containing IUD (TCu380A) (control group) were randomly placed in 932 study patients after induced abortion, 466 in each group, Months, 3 months, 6 months, 12 months regular follow-up. Results: 930 patients completed 12 months of follow-up, 2 patients lost to follow-up; no uterine perforation and pregnancy with device; no other causes of medical treatment or personal reasons; the follow-up rate of study group and control group at 12 months (P <0.05). After 1 month, 3 months, 6 months, 12 months after device placement, the average net renewal rate of 1 year of device was 96.14% in the study group (88.41% There was no significant difference between the study group and the control group in cumulative shedding rate (P> 0.05). The removal rate of the study group at one month, three months and six months after implantation was significantly lower than that in the control group, The incidence of IUD incarceration was significantly higher in the study group 1 month after catheterization (P <0.05); at 1 month, 3 months after catheterization, The study group of termination rate related to the use of IUD for 6 months was significantly lower than that of the control group (P <0.05). The incidence of side effects at 1 month, 3 months and 6 months after the device placement was significantly lower in the study group than in the control group (P <0.05). CONCLUSION: The contraceptive effect of MYuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuisuoduan is good after artificial abortion. Although the rate of MYCu IUD withdrawal and side effects is lower than that of TCu380A, the incidence of incarceration is higher than that of TCu380A.
