We recorded visual evoked potentials (VEPs) to flash stimuli in moderately deep anaesthesia when EEG showed burst suppression pattern. Flash VEPs could consistently be recorded in all 8 test subjects during bursts but not during suppressions. We conclude that during isoflurane-induced EEG suppression VEPs to flash stimuli are also suppressed. This effect should be taken into account in evoked potential testing during anaesthesia.
当脑电图显示爆发抑制模式时，我们在中度深度麻醉下记录了对闪光刺激的视觉诱发电位（VEP）。在爆发期间，所有8名受试对象均能持续记录到闪光VEP，但在抑制期间则无法记录到。我们得出结论，在异氟烷诱导的脑电图抑制期间，对闪光刺激的VEP也受到抑制。在麻醉期间进行诱发电位测试时应考虑到这种效应。
