INTRAPARTUM FETAL MONITORING WITH THE CEREBRAL FUNCTION MONITOR

We report a trial of the technical feasibility of monitoring the state of the fetal brain during labour using the Cerebral Function Monitor (CFM). This device was developed for long‐term monitoring of the electroencephalogram (EEG). A tripolar scalp electrode allows removal of the fetal electrocardiograph (ECG) from the fetal EEG. Technically satisfactory recordings were obtained from 15 fetuses during labour for periods of up to 6½ hours before delivery. There were alterations of CFM trace with fetal distress and also during general anaesthesia for Caesarean section.
