Study of awareness during noninhalational anaesthesia

Abstract

Forty-five adult patients underwent a noninhalational anaesthetic method for investigation of awareness during surgery and recall of events associated with surgery in postoperative period. All the patients were divided into two groups. The first group of patients were male and had upper abdominal operations. The second group were female and had lower abdominal operations. No significant difference was found between these two groups either in requirements of depth of anaesthesia or in the evidence of per-operative awakefulness. Eighty percent patients of both the groups showed various signs of peroperative awakefulness but did not recall any events associated with surgery in the postoperative period. There was no report of dream either.
