摘　　要：目的　分析影响引产潜伏期的主要因素与评价引产成功的难易程度。方法　用会阴B超观察 10 5例初产妇宫颈的成熟状态 ,收集临床资料和引产潜伏期 (引产用药至临产的时间 ) ,作Cox模型分析。结果　宫颈长度、内口开张程度和先露高低是引产潜伏期的主要影响因素 ;会阴B超宫颈成熟度评分大于或等于 -4 5的孕妇更易在 12小时内临产。结论　宫颈的成熟状态是影响引产潜伏期的主要因素 。Objective To analyze the factors influencing latency period of induction and predict the inducibility. Methods 105 primiparae underwent cervical assessment by transperineal ultransonography examination.The five indexes of cervical status、other clinical materials and latency period(the period from induction to the onset of labor)were analyzed by Cox multivariate model.Results The width of cervical internal os, the length of the canal and the position of the presenting part were the main factors that influenced the latency period.Primiparae with score≥-4.5 was easy to initiate the onset of labor in 12 hours.Conclusion Cervical status influence the latency period mainly. The transperineal ultransonographyic cervical ripening score is valuable in predicting the inducibility.
