Introduction

Intraoperative awareness (IA) is a rare phenomenon that affects approximately 0.1-0.2% of patients undergoing general anesthesia balanced (GBA).

Material and methods

Observational, descriptive and transversal study to detect probable cases of IA in subjects who were undergoing GBA in the Central Military Hospital. The statistical method used was the relative frequency of occurrence.

Results

We included a sample of 105 patients to whom we applied the questionnaire of Brice in the immediate postoperative period and 24 hours after their surgical procedure. In a six-month study period, were studied 105 individuals who met the inclusion criteria for the study, 51% (54/105) were female and 49% (51/105) men. Laparoscopic cholecystectomy (29%) was the most common intervention. We applied the questionnaire of Brice in the immediate postoperative period to all individuals included in the study (100%; 105/105). Three probable cases of IA were detected, representing 2.8% of the universe of study.

Conclusions

The questionnaire of Brice was a tool that was easy to use, inexpensive, viable, and free of negative clinical organizational impact to detect probable cases of IA in the institution.
