| Abstract | Visual evoked potentials were recorded in eight children during hypothermia and circulatory arrest. The potentials were lost in all children recorded in late arrest. The evoked potential is a more sensitive indicator of CNS stress as provoked by combined hypothermia and hypoxia than is the EEG. EEG activity persisted in six of the eight children in this series even during circulatory arrest. The EEG had been seen to do the same in more than half of a larger series of children recorded at that stage. The results suggest that evoked potentials may be a sensitive indicator of early impairment of cerebral function and may demonstrate useful change sooner than the EEG. The examination may be useful in following children with illnesses producing hypoxia or anoxia. The N1 component was as easily and as frequently identifiable as the P2 component. Under the stress of this procedure, the latency of the P2 component became more variable than the N1 peak. The results suggest the N1 component may be as useful and perhaps more useful than the P2 wave in following the effect of some CNS stresses in children. |
