目的 :比较徒手和卵圆钳两种方法对产后立即放置 (IPP1)宫内节育器 (IUD)效果的影响。方法 :将 910例阴道分娩产妇 (其中 97.7%是首次分娩 )随机分成两组 ,于胎盘娩出后 10min内放置TCu380AIUD ,其中 470例徒手放置 (手放组 ) ,44 0例用卵圆钳放置 (钳放组 )。随访 12个月 ,以生命表法计、χ2 检验比较两种放置方法的脱落率、妊娠率、因症取出率等。结果 :6和 12个月的随访率分别为 95 .16 %和 92 .6 4%。 910例中未发生子宫穿孔和感染 ,仅手放组有 1例带器妊娠。放置后主要停用原因是脱落 ,手放组与钳放组 12个月的粗累积脱落率分别为 15 .86 / 10 0妇女和 15 .88/ 10 0妇女 ,因症 (出血、疼痛 )取出率分别为 2 .11/ 10 0妇女和 1.5 7/ 10 0妇女 ,差异无显著性 (P均 >0 .0 5 )。结论 :徒手放置或卵圆钳放置对IPP1的效果无明显影响 ;TCu380AIUD适合中国妇女产后立即放置。
OBJECTIVE: To compare the effects of both manual and oval forceps on the efficacy of IPP1 intrauterine devices (IUD). Methods: 910 cases of vaginal delivery of maternal (97.7% of them were first deliveries) were randomly divided into two groups. TCu380AIUD was placed within 10 minutes after the delivery of the placenta, of which 470 cases were placed by hand Clamp release group). Follow-up of 12 months, the life table method, χ2 test compared the two methods of placement shedding rate, pregnancy rate, due to disease removal rate. Results: The follow-up rates at 6 and 12 months were 95.16% and 92.64% respectively. Uterine perforation and infection did not occur in 910 cases, and only 1 case of pregnancy with hand in the hand group. The main reason for discontinuation after the placement was exfoliation. The gross cumulative exfoliation rates at 12 months in the arm and arm groups were 15.86 / 10 0 and 15 .88 / 10 0 women, respectively, due to the disease (bleeding, pain) Rates were 2.11 / 10 0 women and 1.5 7/10 0 women, the difference was not significant (P all> 0.05). Conclusion: The placement of bare hands or oval forceps has no effect on IPP1. TCu380AIUD is suitable for Chinese women to place immediately after delivery.
