  • Title: [Study on evaluation of fetal scalp tissue pH value during labor].
    Author: Li W, Li T, Ding C.
    Journal: Zhonghua Fu Chan Ke Za Zhi; 1996 Mar; 31(3):149-51. PubMed ID: 8758787.
    Abstract:
    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.
