Fetal distress and the condition of the newborn using cardiotocography and fetal blood analysis during labour.
The efficacy of electronic fetal monitoring combined with fetal blood analysis during labour in identifying fetal distress was investigated in a retrospective study. Operative delivery for fetal distress diagnosed during labour was performed in 9% of 2659 deliveries. All had continuous fetal heart rate monitoring and 22% had a fetal scalp blood analysis. Operative delivery had been performed in 53% of the infants who were acidotic at birth (umbilical artery pH less than 7.20) and in 46% of those with a low modified Apgar score (less than 7). These results show that the use of continuous fetal heart rate monitoring and fetal scalp blood sampling detects fetal distress without resulting in a high rate of operative delivery.
