Abstract:

Although rare, reports of recall of intraoperative events continue to occur during general anesthesia. The purpose of this pilot study was to attempt to prompt recall in subjects undergoing general anesthesia GA by presenting the subject a pleasant preoperative suggestion. An experimental study was conducted on a convenience sample of 14 patients, ASA class I or II, aged 20-65, admitted to the University of Tennessee Medical Center for general surgery. Exclusion criteria included patients requiring preoperative medication with benzodiazepines, use of psychotropic drugs, substance abuse, or those with mental or organic brain diseases. Procedures under 30 minutes and intracranial procedures were also excluded. Anesthetic technique was uniform for both the experimental and control group. No aspect of drug or patient care was randomized, all patients received a standard, non-experimental anesthetic technique. Anesthesia was induced with propofol 2.5 mgkg and maintained with N20 and isoflurane. Maintenance doses of fentanyl 50 mcgkg were administered as needed for analgesia. Data was collected and measured in a postoperative interview, in which patients were questioned about intraoperative recall. Statistical analysis was not done due to no reports of dreaming or recall from either group. No correlations existed. Means and standard deviations were given for each group and showed no significant differences in the groups age or-anesthetic time. Failure to produce significant results should not discourage anesthesia personnel from seeking ways to make the surgical experience less stressful. In doing so there may be a decrease in postoperative recovery time, analgesia requirements, and hospital costs.
