In a large randomized, controlled study of fetal heart rate monitoring with either continuous electronic fetal heart monitoring or auscultation at specified intervals, only one pattern of deviation in the fetal heart rate correlated significantly with neonatal neurologic examinations at 0 to 48 hours and 72 hours to 1 week: late decelerations in stage 1 and in stage 2. Other variables from labor and delivery, specifically, duration of labor after hospital admission, failure of labor to progress, number of fetal scalp pH values, and presence of meconium were important predictors of neonatal outcome in the regression analyses. The fetal heart rate deviations did contribute significantly to the percent variance accounted for in the regression analyses with neonatal outcomes of Apgar scores at 1 and 5 minutes and serial neonatal neurologic examinations.
在一项针对胎儿心率监测的大型随机对照研究中，该研究采用连续电子胎儿心率监测或按特定间隔进行听诊，只有一种胎儿心率偏差模式与出生后0至48小时以及72小时至1周时的新生儿神经学检查结果显著相关：第一产程和第二产程中的晚期减速。分娩过程中的其他变量，具体而言，入院后产程时长、产程进展受阻、胎儿头皮血pH值检测次数以及胎粪的存在情况，在回归分析中是新生儿结局的重要预测指标。在对1分钟和5分钟阿氏评分以及一系列新生儿神经学检查的新生儿结局进行的回归分析中，胎儿心率偏差确实对所解释的方差百分比有显著贡献。
