Objective To investigate clinical efficiency of Gynefix intrauterine uterine device. Methods 126 peoples used Gynefix intrauterine uterine device were selected in the hospital from December 2008 to November 2011 as the observation group. 125 peoples used TCu200 intrauterine uterine device were randomly selected in the hospital as the control group. All of IUD users were followed up for 1 years. The contraceptive efficacy and adverse reaction were compared between two groups. Results The effective contraception rate (95.2%) in the observation group was significantly higher than that in the control group (72.8%). The contraceptive failure rate (1.6%) and for some reason extraction rate (3.2% ) in the observation group was significantly lower than contraceptive failure rate(8.8% ) and for some reason extraction rate (18.4%) in the control group. The rate of adverse reactions (10.3%) in the observation group was significantly lower than that in the control group (22.4%). The differences were statistically significant (P<0.05). Conclusion The use of Gynefix intrauterine uterine device has good clinical effect. The effective contraception rate is high while adverse reactions are low. That is a safe and effective method of contraception. That is worthy of clinical use.%目的 探讨固定式吉妮宫内节育器的临床疗效.方法 选取本院2008年12月至2010年11月固定式吉妮宫内节育器使用者126例作为观察组,随机选取在我院使用Tcu200节育器避孕者125例作为对照组,并对所有节育器使用者进行1年随访,比较两组人员的避孕效果和不良反应情况.结果 观察组有效避孕率(95.2％)明显高于对照组(72.8％),观察组避孕失败率(1.6％)和因故取出率(3.2％)明显低于对照组(8.8％、18.4％),观察组不良反应率(10.3％)明显低于对照组(22.4％),差异均有统计学意义(P＜0.05).结论 应用固定式吉妮宫内节育器的临床效果显著,有效避孕率高且不良反应低,是一种安全可行的避孕方法,值得临床推广使用.
