【目的】探讨影响紧急宫颈环扎手术疗效的相关因素。【方法】收集宫颈机能不全并行紧急宫颈环扎术的患者80例，根据手术后妊娠结局分为成功组和失败组，比较两组术前宫缩次数、宫口≥4 cm 者例数、术前血清 C 反应蛋白（CRP）水平、焦虑等，分析影响手术疗效的相关因素。【结果】失败组术前宫缩次数、宫口≥4 cm 者评分、术前血清 CRP 水平、焦虑和（或）抑郁患者百分比均大于成功组（ P ＞0．05）；失败组术后延长的孕周小于成功组，感染率高于成功组（ P ＞0．05）；相关性分析显示：术前宫缩、宫口开大程度、CRP 和术后延长孕周与紧急宫颈环扎手术疗效密切相关。【结论】紧急宫颈环扎术可有效改善宫颈机能不全患者的妊娠结局；术前宫缩、宫口扩大程度、CRP 和术后延长孕周与紧急宫颈环扎手术疗效密切相关。“,”Objective] To explore the relevant influencing factors for emergency cervical cerclage .[Methods]From January 2012 to December 2014 at our hospital ,a total of 80 patients undergoing emergency cervical cerclage were recruited .According to the surgical outcomes ,they were divided into success and failure groups .All clinical da‐ta were collected and analyzed .[Results] By comparison ,preoperative contraction frequency ,cervix ≥ 4 cm ,preop‐erative serum level of C‐reactive protein (CRP) and proportions with depression and /or anxiety in failure group were more than those in success group .And the prolonged gestation of failure group was shorter than that of success group .And the rate of infection was higher than success group .There was no correlation with age ,weight or gravid‐ity( P < 0 .05) .[Conclusion] Emergency cervical cerclage can effectively improve pregnancy outcomes in patients with preoperative insufficiency of uterine cervix .And preoperative contractions ,extent of cervical expansion ,infection prolonged gestation ,depression and anxiety are influencing factors .
