✦ Synopsis

Reaction times and evoked electroenccphalographie responses to tone stimuli were measured using a LINC-8 computer on-line. The effects on these measures of inhaling 10, 20 and 30~ nitrous oxide in oxygen were compared with those of pure oxygen in twelve normal subjects. Each subject gave 50 responses under each drug condition.

Nitrous oxide prolonged reaction time and diminished all components of the evoked responses in a regular dose-related manner. The form of the evoked response was also related to speed of reaction time. These findings arc briefly discussed in terms of processes of attention and arousal.

Inhalational anaesthetics inhibit somatosensory evoked potentials. The present study examined the effect of nitrous oxide in anaesthetic mixture with sevoflurane on the somatosensory evoked potential in children. Forty‐five patients aged between 6 months and 6 years undergoing club foot surgery were
