胎膜早破患者宫颈评分与分娩各时相及分娩方式的关系

目的：比较不同宫颈评分的胎膜早破患者其破水至临产、分娩等各时间段的差异，及其与分娩方式的关系，为合理的临床处理提供依据。方法：选取我院2007年足月及近足月胎膜早破并自然临产患者资料共219例，按宫颈评分将产妇分成两组，即宫颈成熟纽（0-5分）及宫颈不成熟纽（6分及以上），分析宫颈评分与破水至临产时间、产程及分娩方式的关系。结果：宫颈评分与破水临产时间呈负相关，r=-0．167，P=0．013；宫颈成熟组破水-临产时间更短（8．93±7．29h），宫颈不成熟组破水-临产时间较长（13．32±7．83h）。宫颈成熟组阴道分娩率更高。结论：宫颈成熟的胎膜早破患者需较短的时间即可临产，促进宫颈成熟，可缩短破水-临产时间，降低剖宫产率。

objective ：To compare the intervals between PROM and onset of uterine contractions, delivery stage, and the mode of delivery in patiena with PROM at term and with different bishop scores, methods：219 patients with PROM were divided into two grounps：group A（ Bishop seorea≤5） and group B（ Bishop scores ≥6）. The PROM -onset of contracts interval, delivery stage and mode of delivery of the two groups were studied, results： There is negative relashionship was observed between Bishop scores and interval of PROM - onset of uterine contractions, r = -0. 167, P = 0.013. The interal of PROM - onset of contractions in group B （8.93 ± 7.29hours） is shorter than in group A （13.32 ± 7.83hours）. And the rate of vaginal delivery is higher in group B than＂ in group A. eonelusion ： The higher the Bishop scores is, the shorter the PROM - onset of contractions is, and the higher the rate of vaginal delivery is. Promoting the cervleal riping can perhaps shorten the interval of PROM- delivery and reduce the rate of cesarean delivery.
