摘要: The latency of the early cortical wave Nb auditory evoked response (AER) was compared with responses to Tunstall's isolated forearm test, while, concentration nitrous oxide progressively reduced during light anaesthesia in seven patients. A threshold 44.5 ms chosen discriminate between an AER containing three waves and that two longer latency. When decreased below this threshold, four patients has positive responses, indicating awareness. addition a volatile anaesthetic abolished any response, increased more than ms. pattern, therefore, is associated depth at which awareness occurs.
