An adequate trial of labor preceding cesarean delivery for arrest of cervical dilatation in the active phase of labor has not been defined precisely. We reviewed the records of 85 consecutive women at term who received oxytocin for induction or augmentation of labor and who subsequently delivered by cesarean for arrest of labor in the active phase. The mean duration of oxytocin infusion was 15 hours for induction of labor and 8.9 hours for augmentation. Thirty-four (92%) of the 37 women who received oxytocin induction and 44 (92%) of the 48 who had oxytocin for augmentation achieved at least 200 Montevideo units of uterine pressure. All 85 newborns were vigorous at birth and had no complications during their stay in the hospital nursery. Evaluation of uterine contraction pressure can provide a quantifiable end point for the management of oxytocin induction or augmentation of labor.
对于产程活跃期宫颈扩张停滞而行剖宫产之前进行充分的试产，目前尚无精确的定义。我们回顾了85例足月连续产妇的记录，这些产妇接受缩宫素引产或加强宫缩，随后因产程活跃期产程停滞而行剖宫产。引产时缩宫素输注的平均时长为15小时，加强宫缩时为8.9小时。接受缩宫素引产的37例产妇中有34例（92%），接受缩宫素加强宫缩的48例产妇中有44例（92%），子宫压力至少达到200蒙特维的亚单位。所有85例新生儿出生时均活力良好，在医院新生儿病房期间无并发症。评估子宫收缩压力可为缩宫素引产或加强宫缩的管理提供一个可量化的终点。
