[Verification of KTG recording in states of perinatal partial asphyxia using fetal capillary blood pH].

We analysed 91 cases of pH-metric verifications of pre-pathological and pathological cardiotocograms, which suggested imminent perinatal partial asphyxia. In 50% of cases there was no need for medical intervention, this groups of patients delivered vaginally and newborns were in good condition. In 80% pH value well correlated with state of newborn at birth. Pre-pathological cardiotocograms showed mainly variable decelerations, pH value didn't show acidosis and afterbirth umbilical cord collision was stated. In pathological cardiotocograms we observed mainly late decelerations, pH value showed fetal acidosis which coexisted with placental insufficiency in prolonged gestation.
