To investigate the effect of initiating labor by oxytocin infusion on the outcome of delivery in cephalic presentation, the dystocia rate and final modes of delivery were analyzed in 3,090 cases of head presentation using oxytocin infusion and 2,982 cases with spontaneous onset of labor as control group. The results showed that 562 of the cases using oxytocin developed cephalic dystocia, a rate of 18.2%, while 371(12.4%) of the control group had dystocia. Besides, cephalic dystocia, rates of episiotomy, vacuum extraction and cesarean section were all significantly higher in the oxytocin group than those in the control (P < 0.005). Data also showed that the higher dosage, the more frequency and the longer time of pitocin infusion the higher the rate of dystocia.
为探讨静脉滴注缩宫素引产对头位分娩结局的影响，分析3090例使用缩宫素引产的头位分娩病例及2982例自然临产病例（作为对照组）的难产率及最终分娩方式。结果显示，使用缩宫素的病例中有562例发生头位难产，发生率为18.2%，而对照组中有371例（12.4%）发生难产。此外，缩宫素组的头位难产、会阴切开术、胎头吸引术及剖宫产率均显著高于对照组（P<0.005）。数据还显示，缩宫素剂量越大、滴注频率越高、时间越长，难产率越高。
