Abstract

Background: The incidence of awareness with recall during general combined with epidural anesthesia has not been previously reported. The purpose of this study was to quantify the incidence.

Materials & methods: One hundred patients were divided into two groups. Group 1 (N = 50) received general anesthesia (GA), Group 2 (N = 50) received GA and epidural anesthesia (EA) intraoperatively. No premedication was given. These patients were induced with thiopentol (5 mg/kg) or propofol (2.0 mg/kg) and anectine (1.2 mg/kg) for smooth tracheal intubation and maintained with N2O:O2 = 1.5:1.5, and isoflurane and muscle relaxant of either pavulon or atracurium. No sedatives was given. Before anesthesia, we introduced an epidural catheter into the group 2 patients. After induction, headphones with soft music were given to the patients, in both groups, throughout the operation. 20-36 hours after operation or when the patients were fully awake, we asked the patients if they had heard anything or dreamed intraoperatively.

Results: We found that not one of the one hundred patients heard anything or dreamed intraoperatively.
