Bispecteral index facilitates postoperative recovery of elderly patients undergoing abdominal surgery

Introduction: Elderly is considered from 60-65 years old, and 35% of all surgeries related to this age group. Surgical complications in these patients have a high incidence and to reduce these complications Bispectral (BIS) monitoring during the anesthesia can be used. This study was designed to investigate whether BIS monitoring improves clinical anesthetic delivery, recovery profiles in elderly patients undergoing abdominal surgery with general anesthesia compared to standard clinical practice. Methods: In a clinical trial, 68 elderly patients (over the age of 60) having American Society of Anesthesiologists (ASA) physical status of I or III who were scheduled for elective abdominal surgery. Patients were randomly allocated to two groups that receiving general anesthesia with BIS monitoring as cases and without using of BIS monitoring as controls. To compare two groups, Kaplan-Meier test was used. Results: The time to orientation was faster in the BIS group compared to the control group. There were significant differences in the postoperative orientation time between the two groups. (P<0.001) Conclusion: Our findings indicate that, recovery time and discharge from recovery in BIS group was significantly faster than control group.
