| Abstract: | Summary. There are controversies over the effect of nitous oxide on the electrocorticograms in patients with epilepsy. To clarify the effect of nitrous oxide on electrocorticograms, spike activities were compared with and without nitrous oxide under neuroleptoanesthesia in 10 patients with intractable epilepsy during surgery. Spikes decreased with nitous oxide significantly (P<0.01) and disappeared in 3 cases. We conclude that discontinuation of nitrous oxide should be taken into consideration during electrocorticographic monitoring in epilepsy surgery. |
