目的观察MYCu宫内节育器(intrauterine device,IUD)与MCuⅡ功能性宫内节育器(MCuⅡIUD)的临床效果及安全性。方法 1 400例妇女随机分为MYCu组和MCuⅡ组,分别放置MYCu IUD和MCuⅡIUD,术后第1、3、6、12、24、36个月对受术者进行随访。结果放置满36个月,MYCu组与MCuⅡ组带器妊娠率分别为0.74/百妇女年、0.73/百妇女年;脱落率分别为0.58/百妇女年、0.59/百妇女年;因医疗原因取出分别为2.21/百妇女年、3.40/百妇女年;主要不良反应为出血和疼痛;以上各项比较差异均无统计学意义(P>0.05)。放置后1、3个月时月经异常及腰腹疼痛发生率MCuⅡ组高于MYCu组(P<0.05)。结论MYCu IUD与MCuⅡIUD同样具有抗生育效果好、脱落率低、不良反应少的特点,放置MYCu IUD可减少IUD放置初期的出血和疼痛。
Objective To observe the clinical effect and safety of MYCu intrauterine device (IUD) and MCuⅡ functional intrauterine device (MCuⅡIUD). Methods One hundred and forty-four women were randomly divided into three groups: the MYCu group and the MCuII group, with MYCu IUD and MCuIIIUD respectively. The patients were followed up on the 1st, 3rd, 6th, 12th, 24th and 36th month after operation. The results were placed for 36 months. The pregnancy rates of group MYCu and MCuⅡ were 0.74 per hundred women and 0.73 per hundred women, respectively; the rates of shedding were 0.58 per hundred women and 0.59 per hundred women per year respectively; Respectively, 2.21 / Hundred Years Women, 3.40 / Hundred Years Women; The main adverse reactions were bleeding and pain; The above differences were not statistically significant (P> 0.05). The abnormal menstruation and the incidence of lumbar pain in the MCuⅡ group were higher than those in the MYCu group (P <0.05) at 1 and 3 months after placement. Conclusions MYCu IUD and MCuIIIUD also have the characteristics of good anti-fertility, low exfoliation rate and few adverse reactions. Placement of MYCu IUD can reduce bleeding and pain in the initial stage of IUD placement.
