[摘要] 目的 探讨对宫颈机能不全导致宫颈扩张的孕产妇行紧急宫颈环扎术对分娩结局及胎儿存活率的临床疗效与意义。 方法 选择我院产科宫颈机能不全导致宫颈扩张产妇124例随机分为A、B两组。A组患者使用宫缩抑制药物进行保守治疗；B组在A组基础上联合紧急宫颈环扎术治疗。比较两组患者不同方法治疗后分娩时间、分娩方式及胎儿阿氏评分等相关指标。 结果 联合紧急宫颈环扎术手术B组患者足月生产人数显著多于保守治疗A组，分娩时未到足月患者人数显著少于A组(P<0.05)，B组术后自然分娩人数51例，胎儿阿氏评分(8.6±0.41)分均显著高于保守治疗A组32例，(6.3±0.40)分(P<0.05)。 结论 对由于宫颈机能不全导致宫颈扩张的产妇行紧急宫颈环扎术能够可显著减少宫缩次数，延长胎龄，帮助胎儿在母体内进行更好的生长发育；对改善分娩结局，提高新生儿存活率具有重要意义。
