本文对两种新型固定式宫内节育器(Fix-TCu220-M和GyneFix PP)在阴道产或剖腹产胎盘娩出后立即放置后,进行42天,6,12个月时临床妊娠率、脱落率、因症取出率的比较性研究。结果显示Fix-TCu220-M组妊娠率为0.32％,脱落率为0.64％,因症取出率为1.92％;GyneFixPP组分别为0,1.96％和0。由此可见,脱落率GyneFix PP组稍高于Fix-TCU220-M组;出血、疼痛取出率后者稍高于前者。但此两种新型固定式宫内节育器在阴道产或剖腹产后立即放置,其避孕效果一致,皆优于其它类型的宫内节育器,为值得推荐之新型产后避孕器具。
In this paper, two new fixed intrauterine devices (Fix-TCu220-M and GyneFix PP) were placed immediately after the delivery of vaginal or caesarean section placenta, at 42 days, 6,12 months clinical pregnancy rate, Symptom extraction rate of comparative study. The results showed that the pregnancy rate of Fix-TCu220-M group was 0.32%, the rate of shedding was 0.64% and the rate of removal was 1.92%. The GyneFixPP group was 0, 1.96% and 0 respectively. Thus, the rate of shedding GyneFix PP group slightly higher than the Fix-TCU220-M group; bleeding, the pain rate of the latter was slightly higher than the former. However, the two new type of IUDs placed immediately after vaginal delivery or caesarean section have the same contraceptive effect and are superior to other types of IUDs. It is a new postpartum contraceptive device worth recommending.
