Background: The need for increasing operating room efficiency has led to various initiatives, one of which is the elimination of mandatory admission to the phase I recovery area postoperatively, also referred to asfast tracking of ambulatory surgery patients. This Institutional Review Board-approved study was conducted to evaluate the effect of Bispectral Index (BIS) monitoring on the ability of patients to successfully bypass the phase I recovery area following gynecologic laparoscopy during general anesthesia. Methods: Ninety-nine consenting patients were randomly assigned to one of two groups: group one, in which the BIS® monitor (Aspect Medical Systems, Natick, MA) was used, and group two, in which no BIS® monitor was used. All patients received a standardized anesthetic that included 1 μg/kg sufentanil and sevoflurane in oxygen, titrated in group one to a BIS value of 50-60 and in group two to maintain vital signs within 20% of preoperative values. All patients received prophylactic nonsteroidal antiinflammatory drugs and antiemetics. Postoperatively, patients were evaluated using the modified Aldrete scoring system, and those who achieved a score of 9 or higher within 10 min were permitted to bypass the phase I recovery area. Results. There was no statistically significant difference between the two groups with respect to the number of patients who successfully bypassed the phase I recovery area, postoperative length of hospital stay, or cost of hospitalization. Conclusion: With a standardized anesthetic regimen and a strict discharge scoring system, BIS monitoring does not have a significant effect on the ability to fast track outpatients.
