Doppler waveform analysis of the umbilical artery was performed on 42 patients with decelerations of the fetal heart rate during the first stage of labour. A fetal scalp blood sample was analysed or caesarean section was performed. At delivery the umbilical vein pH was estimated. A significant negative correlation between the umbilical vein pH and the pulsatility index of the Doppler waveform was found (r = -0.59). There was not a significant correlation between the pulsatility index and the scalp pH measurement. The use of Doppler waveform analysis in labour is discussed.
对42例在第一产程出现胎儿心率减速的患者进行了脐动脉多普勒波形分析。分析了胎儿头皮血样本或实施了剖宫产。分娩时估计了脐静脉pH值。发现脐静脉pH值与多普勒波形搏动指数之间存在显著负相关（r = -0.59）。搏动指数与头皮pH测量值之间无显著相关性。文中讨论了多普勒波形分析在产程中的应用。
