Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Adult patients will be evaluated 4 time following emergence (a) One hour after emergence, (b) Twenty four hour after emergence (c) One week after emergence (d) One month after emergence. The first interview will be made face-to-face in the recovery unit, and other interviews will be made by phone. Each interview will be conducted using the same structured interview (Brice Interview).
Descriptive statistics will be used to determine the incidence of awareness. χ2 test will be used for comparison between groups. Logistic regression will be used to determine the risk factors associated with awareness and PTSD.
We believe that this study will contribute to the prevention of the problem by determining the real frequency and causes of intraoperative awareness under general anesthesia, determining the experiences and results of patients, and analyzing the associated risk factors.
