Incidence of Unintended Intraoperative Awarness in Total Intravenous Anesthesia Using Modified Brice Scoring System as a Tool

Abstract

Objective: Current study was planned to assess the incidence of awareness in patients undergoing general anesthesia (GA).

Methodology: Cross sectional study was conducted at Sindh Employees Social Security Hospital Landhi Karachi from June 2021 to May 2022 in one-year duration.  A total of 200 patients who underwent various surgical procedures, including septoplasty, endoscopic sinus surgery (FESS), mastoidectomy, laparoscopic procedures, all performed under general anesthesia. Primary variable of study was intraoperative awareness that was assessed by using Brice scoring system.

Results: Modified Brice questions were asked to all of the patients. It was seen that 96.5% patients completely asleep for this operation. 9.5% patient’s memory about going to sleep and waking up. 8.0% patients had dream during the procedure. In our study, 9.5% patients were aware categorized as A, 36.0% patients were possible aware categorized as B and 54.5% patients had no awareness.

Conclusion: The current study reveals a notably elevated incidence of intraoperative awareness in patient when compared to previous research, indicating a significant association between awareness and comorbidities among individuals undergoing surgery under general anesthesia.
