摘要目的 观察3种宫内节育器(IUD)GyneFix IN、MCu、TCu220C的临床避孕效果.方法 2005年1月至2006年12月我院以随机方法选择放置IUD,GyneFix IN IUD、MCu IUD、TCu220C IUD各100例,于放置后1、3、6、12个月进行对比性研究.结果 放置IUD 12个月随访,3种IUD带器妊娠率[2%(2/100)、4%(4/100)和5%(5/100)]比较,差异无统计学意义(X2=1.29,P>0.05);GyneFix IN IUD和MCu IUD的脱落率[均为3%(3/100)]低于TCu220C IUD[22%(22/100)],差异有统计学意义(X2=28.44,P<0.01);GyneFix IN IUD和MCu IUD的因症取出率[4%(4/100)、10%(10/100)]低于TCu220C IUD[24%(24/100)],差异有统计学意义(X2=19.04,P<0.05);GyneFix IN IUD和MCu IUD的12个月的累积续用率[91%(91/100)和83%(83/100)]高于TCu220C IUD[50%(50/100)],差异有统计学意义(X2=49.94,P<O.01).结论 GyneFix IN IUD和MCu IUD具有脱落率低、因症取出率低、累积续用率高的优点,值得临床应用.

abstractsObjective To observe the clinical contraeeption effects of GyneFix IN IUD,MCu IUD and TCu220C IUD.Methods From January 2005 to December 2006,comparative study was carried out by randomly applying 3 different types of IUDs(GyneFix IN,MCu and TCu220C IUD) for 300 healthy women.Follow-up survey was taken after 1,3,6,and 12 months.Results The pregnancy rates with IUD among 3 types of IUDs showed no significant difference(P>0.05).The expulsion rates of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.01).The removal rate of GyneFix IN IUD and MCu IUD were lower than that of TCu220C IUD(P<0.05).The 12 months cumulative continuation rates of GyneFix IN IUD and MCu IUD were higher than that of TCu220C IUD(P<0.01).Conclusions GyneFix IN IUD and MCu IUD can be recommended for clinical use based upon the advantages of lower pregnancy rate,lower removsl rate because of side-effect and higher cumulative continuation rate.Proper IUD should be selected depending on individuals,in order to increase the contraception effects and decrease the side-effects.
