宫颈环扎术对妊娠结局的影响

The effect of cervical cerclage on the outcome of pregnancies

目的 探讨宫颈环扎术对妊娠结局的影响。方法 对我院 1 977～ 2 0 0 0年间因宫颈功能不全行宫颈环扎术者 2 79例次的临床资料进行回顾性分析 ,评价环扎术对妊娠结局的影响。结果 环扎术后足月妊娠率(79.93 % )及新生儿存活率 (91 .0 4 % )均明显提高 (P <0 .0 1 ) ;分娩孕周与环扎术时孕周呈正相关 (r =0 .57,P<0 .0 5) ,与既往早 (流 )产数呈负相关 (r =- 0 .53 ,P <0 .0 5) ,而与既往环扎术史无相关 (P >0 .0 5)。胎膜早破及宫颈裂伤的的发生与环扎时孕周、既往早 (流 )产数及既往环扎术史无明显相关 (P >0 .0 5)。

Objective To study the effect of cervical cerclage on the outcome of pregnancies. Methods Retrospective analysis was made on 279 cases of cervical cerclage. Results The rates of term birth and neonatal survival were increased significantly (P<0.05). There was a positive correlation between the gestational age at delivery and that at cerclage(r=0.57,P<0.05), and a negative correlation between the former one and the number of previous spontaneous abortions/premature deliveries(r=-0.53,P<0.05). The gestational age at delivery was not correlated with the history of prior cerclage placement(P>0.05). There was no correlation between the complications (premature rupture of membrane, cervical lacerations) and the determinants of cerclage placement (P>0.05). Conclusion Cervical cerclage is a safe and effective treatment for cervical incompetence.
