人工流产术后即时放置不同宫内节育器的效果比较

目的比较三种宫内节育器（IUD）在人工流产术后即时放置的临床效果。方法对120例人工流产术后即时放置IUD患者进行随访，按放置IUD的类型分为TCu3s0AIUD组40例、活性1型IUD组40例、宫铜ZooIUD组40例，随访12个月，比较三组临床效果。结果三组均无带IUD妊娠。IUD终止使用率：宫铜ZooIUD组27．5％、活性1型IUD组7．5％、TCu3s0AIUD组15．0％，三组终止使用率差异有统计学意义（F=5．88，P〈0．05）；三组间IUD并发症发生情况差异均无统计学意义（均P〉0．05）。随访12个月，宫铜zooIuD组月经增多发生率42．5％，明显高于其他两组的15．0％、20．0％（F=8．96，P〈0．05）；不规则出血三组间差异有统计学意义（F=17．77，P〈0．01）。结论三种IUD均具有良好的避孕效果，其中活性γ型IUD不良反应较小，继续使用率较高。

Chinical effects of three kinds of active IUD inserted immediately after induced abortion

Objective To compare the effects of three types intrauterine device （IUD） insertion immediately after vacuum aspiration. Methods 120 cases of artificial abortion immediately placed IUD women were selected. Ac- cording to the IUD type,the patients were divided into the TCu3s0AIUD group 40 cases,active gamma type 40 cases in group IUD, palace copper 40 cases in ZooIUD group, followed up for 12 months. Results All of the subjects were not with IUD pregnancy. The termiration rate was Palace copper ZooIUD group 27.5% ,active gamma type IUD group 7.5% TCu3s0AIUD 15.0%, three groups of termination rate had a significant difference （F = 5.88, P 〈 0.05 ） ;three group IUD complications had no statistical difference （ all P 〉 0.05 ）. Follow-up for 12 months, palace copper group ZooIUD menstruation increase incidence rate of 42.5%, significantly higher than the other two groups 15.0% ,20.0% （ F = 8.96, P 〈 0.05 ） ; the difference between the three groups in irregular bleeding was significant （ F = 17.77, P 〈 0.01 ）. Conclusion The three kinds of IUD has good contraception effect,wherein the active gamma IUD has smaller adverse reaction, continue to use rate is high, so it is worthy of clinical application.
