To evaluate the effectiveness of emergency cervical cerclage and to determine predictors of failure or success in women with cervical incompetence.
Medical records were reviewed for clinical and demographic data, gestational age at time of cerclage, cerclage-delivery interval, gestational age at time of delivery; and birth weight. Predictors of success and failure were analyzed.
Forty-three pregnant women between 18 and 25 weeks of gestation were recruited. The mean gestational age at time of cerclage was 21 weeks. The mean cerclage-delivery interval was 64 days. The mean gestation at delivery was 31 weeks and the mean neonatal birth weight was 2166 g. Whether cerclage done before or after 20 weeks, the difference in cerclage-delivery interval was insignificant while the difference in gestational age at time of delivery and neonatal birth weight was significant. Presence of infection, presence of symptoms, membranes through the cervix and dilated cervix >3 cm are frequently associated with failure.
Emergency cervical cerclage is effective in prolonging pregnancy and improving neonatal outcome in patient with cervical incompetence. However, large prospective randomized controlled studies are recommended.
评估紧急宫颈环扎术的有效性，并确定宫颈机能不全女性手术失败或成功的预测因素。
回顾病历以获取临床和人口统计学数据、环扎时的孕周、环扎至分娩间隔、分娩时的孕周以及出生体重。分析手术成功和失败的预测因素。
招募了43例妊娠18至25周的孕妇。环扎时的平均孕周为21周。环扎至分娩的平均间隔为64天。分娩时的平均孕周为31周，新生儿平均出生体重为2166克。无论环扎在20周之前还是之后进行，环扎至分娩间隔的差异不显著，而分娩时孕周和新生儿出生体重的差异显著。感染的存在、症状的存在、宫颈胎膜破裂以及宫颈扩张>3 cm常与手术失败相关。
紧急宫颈环扎术对于延长宫颈机能不全患者的孕周和改善新生儿结局是有效的。然而，建议开展大型前瞻性随机对照研究。
