EEGs during inhalation of analgesic concentrations of 30%, 50%, and 70% nitrous oxide in oxygen, in the absence of other medication were studied in man. Although nitrous oxide has been considered to produce no significant change in EEG activity, it was found to produce characteristic fast oscillatory activity (FOA) in a predictable fashion. FOA was associated with unconsciousness or unresponsiveness to stimuli and appeared predominantly in the frontal areas. Power spectrum analyses showed that… CONTINUE READING
