目的探讨宫颈环扎术治疗孕中期宫颈机能不全的疗效。方法将我院2005年2月至2010年10月收治的宫颈机能不全的孕妇43例分为手术组(A组,27例)和非手术组(B组,16例),比较两组的胎儿存活率、平均延长孕周。结果胎儿存活率手术组91.1%,明显高于非手术组47.6%(P<0.01);平均延长孕周:手术组15.3周,明显长于非手术组6.5周(P<0.01)。结论宫颈机能不全是导致妊娠晚期流产和早产的常见原因,实施宫颈环扎术是重要的,可以延长妊娠时间,提高活婴分娩率。
Objective To investigate the effect of cervical cerclage on cervical incompetence in the second trimester. Methods Forty-three pregnant women with cervical incompetence who were treated in our hospital from February 2005 to October 2010 were divided into operation group (group A, n = 27) and non-operation group (group B, n = 16) Survival rate, the average extension of gestational age. Results The survival rate of fetus was 91.1% in operation group, which was significantly higher than that in non-operation group (47.6%, P <0.01). The mean gestational age was 15.3 weeks in operation group and significantly longer than that in non-operation group for 6.5 weeks (P <0.01). Conclusions Cervical incompetence is a common cause of miscarriage and premature delivery in the third trimester of pregnancy. Cervical cerclage is important to prolong the time of pregnancy and increase the delivery rate of living babies.
