OBJECTIVE
To assess the predictive value of serial monitoring fetal scalp tissue pH value (tpH) during labor.
METHOD
Fifty two primipara with singleton and cephalic presentation were recruited during their active phase of labor after rupture of membrane. Their fetal scalp tpH were determined by a new type of alloy pH spiral electrode and pH-LS-1 sensor. These values were compared with the umbilical blood pH values (bpH) measured immediately after delivery.
RESULTS
The fetal tpH values were significantly positive correlated with the bpH values (r = 0.822 and 0.725). The incidence of neonate asphyxia in tpH >or= 7.20 group was significantly lower than those to tpH<7.15 group. No adverse effect was observed in this study.
CONCLUSION
Determination of fetal scalp tpH during labor is of predictive value and harmless fro detecting fetal distress.
目的
评估产程中连续监测胎儿头皮组织pH值（tpH）的预测价值。
方法
选取52例单胎头先露的初产妇，在胎膜破裂后的活跃期产程中进行研究。采用新型合金pH螺旋电极和pH-LS-1传感器测定胎儿头皮tpH值。将这些值与分娩后立即测量的脐血pH值（bpH）进行比较。
结果
胎儿tpH值与bpH值呈显著正相关（r = 0.822和0.725）。tpH≥7.20组新生儿窒息发生率显著低于tpH<7.15组。本研究未观察到不良影响。
结论
产程中测定胎儿头皮tpH对检测胎儿窘迫具有预测价值且无害。
