在 3个中心对含消炎痛铜宫形器 (药铜器 ) 1 0 0 0例进行了一年临床观察 ,并与TCu2 2 0 c(TCu) 1 0 0 0例进行了比较。结果显示妊娠率、脱落率、因症 (出血 /疼痛 )取出率、续用率药铜器组分别为 0 .90、1 .90、0 .70和 96.40 / 1 0 0妇女 ;TCu组分别为 1 .72、1 .40、1 .42和 95 .2 8/ 1 0 0妇女 ;两组比较差异均无统计学意义 (P>0 .0 5 )。但放置 3、6、1 2个月时 ,经量增多发生率药铜器组均明显少于 TCu组 (P<0 .0 0 1 ,P<0 .0 1 ,P<0 .0 0 1 )。经量减少发生率在 3、6、1 2个月药铜器组均高于 TCu组 ,3、1 2个月时两组比较有显著差异 (P<0 .0 0 1 )。经期延长和痛经虽两组发生率均不高 ,但两组差异有显著意义。提示药铜器避孕效果好 ,副反应小 ,尤其在放置一年内出血少
One year of clinical observation of 100 cases of indomethacin-containing copper pyramide (bronze) was performed in three centers and compared with TCu2 2 0c (TCu) 100 cases. The results showed that pregnancy rate, shedding rate, due to disease (bleeding / pain) removal rate, the recovery rate of drug bronze group were 0.90,1 .90,0 .70 and 96.40 / 100 women; TCu group were 1.72,1.40,1 .42 and 95.28 / 100 women. There was no significant difference between the two groups (P> 0.05). However, when placed for 3, 6, and 12 months, the incidence of bronchial increase was significantly less in the drug bronze group than in the TCu group (P <0.01, P <0.01, P <0.01 ). The incidences of decrease in the amount of menstruation were higher in TCI group than those in TCu group at 3, 6 and 12 months, and there was significant difference between the two groups at 3 and 12 months (P <0.01). Menstrual extension and dysmenorrhea, although the incidence was not high in both groups, but the difference between the two groups was significant. Prompt bronchial contraceptive effect, side effects, especially less bleeding within a year
