[The influences of nitrous oxide and ketamine on electroencephalogram during propofol-anesthesia].
The influence of nitrous oxide and ketamine on electroencephalogram (EEG) during the induction of general anesthesia with propofol was quantitatively analyzed. ⋯ When anesthesia is induced with nitrous oxide and/or ketamine together with propofol, and BIS is taken as an index of depth of anesthesia, the intracerebral concentration of propofol becomes excess.
