EEG-changes during general anaesthesia with enflurane (Efrane) in comparison with ether.
The effects of enflurane (efrane) and ether on the cerebral functions were studied by EEG on two similar groups of adult patients. For basic comparison a depth of anaesthesia was chosen which permitted abdominal surgery without the need to administer muscular relaxants. At this level of anaesthesia the typical EEG-changes of paroxysmal type which have been described with enflurane were seen only occasionally. If, however, the depth of anaesthesia was further increased, such EEG-changes indicating increased cerebral excitability were seen more often under enflurane and also appeared under ether anaesthesia. No seizure activity was recorded.
