Methods The stability o.f cupric ion releasing o.f IUDs including TCu 380.4 IUD （TCu 380A）, Multiload Cu375 IUD （MCu 375） and Yuangong 365 copper-bearing indomethacin-releasing IUD （Yuangong 365） by the determination of cupric ion releasing in simulated uterine fluid. The simulated uterine fluid was used for releasing media. Copper ion was determined by flame atomic absorption spectrometer. Results The cupric ion releasing of three IUDs were instable at the beginning and tend to be stable gradually. In the stable phase, the average level of cupric ion releasing of TCu380A, MCu375 and Yuangong 365 were 4.25±2.71-7.62±6.42 μg, 4.92±1.23 -8.62±3.08 μg and 2.19±0.40-4.68±1.66 μg, respectively. TCu380A had higher instable releasing level than those of Yuangong 365 （P〈0. 05）. Conclusion TCu 380.4 and MCu 375 showed a ＂burst release＂ during the first few days and the.former was of great significance（P〈0.05）. The initial cupric ion releasing of Yuangong 365 appeared to be the lowest, followed by MCu375 and TCu380A in a releasing order展开更多

Design: Randomized, comparative study. Setting: Department of obstetrics and gynecology in a primary reference hospital at Puebla City, Mexico. Sample: 396 women requiring CS signed informed consent and were randomly allocated to the post-placental application of LNG-IUS (198) or Copper T 380 A (198). Methods: Follow up visits at 6 weeks, and 6 and 12 months were performed. Main Outcomes Measures: IUDs expulsion, maternal and babies’ health conditions, breastfeeding and menstrual patterns, adverse effects and pregnancies. Differences between groups were analyzed by Fisher and X2 tests, Odds ratios, relative risk and 95% confidence limits, as appropriate. Results: After one year of follow up, no pregnancies were reported. The IUD expulsion rate was 4.5% in each group. LNG-IUS users had a higher incidence of amenorrhea (OR 2.5 95% CI 2.2 - 3) and menstrual patterns significantly brief and lighter than Copper T 380 A (p < 0.001) with lower incidence of dysmenorrhea (OR 0.1 95% CI 0.04 - 0.2). No detrimental effects of LNG-IUS on breastfeeding was observed and interestingly babies weights of LNG-IUS users was slightly above the average for age compared with Copper T 380 A users. This was probably related with a major proportion of women with normal ferritin serum levels (94% vs 68%) leading to better mother’s general condition. Conclusions: LNG-IUS inserted during CS provides high efficacy contraception with additional benefits, mainly reducing menstrual bleeding and doing so, faster recovery of ferrous homeostasis after CS.展开更多
