A quantitative analysis of the oxytocin challenge test (OCT) was carried out in 305 women to evaluate: (1) the intrauterine pressures evoked during the oxytocin infusion, (2) when fetal heart rate (FHR) decelerations are likely to occur, (3) the type and amount of decelerations which are significant, and (4) what clinical events and laboratory parameters correlate with the OCT. If contractions are evoked at a rate of three per 10 minutes, the pressure profile mimics normal labor. The first FHR deceleration is likely to occur between the second and third effective contraction. A deceleration/contraction ratio greater than or equal to 10% significantly forecasts an abnormal FHR during parturition and an increased chance of a cesarean section.
对305名女性进行了催产素激惹试验（OCT）的定量分析，以评估：（1）催产素输注期间诱发的宫内压力；（2）胎儿心率（FHR）减速可能出现的时间；（3）有意义的减速类型和数量；（4）哪些临床事件和实验室参数与OCT相关。如果以每10分钟3次的频率诱发宫缩，压力曲线模拟正常分娩。首次FHR减速可能发生在第二次和第三次有效宫缩之间。减速/宫缩比大于或等于10%显著预示分娩期间FHR异常及剖宫产几率增加。
