In plain words

What the trial is, and whether it could suit you

The goal of this observational study is to explore the variability of the concentration at the effect site (Ce) of propofol to reach deep anesthesia (DA) during induction of general anesthesia in adults. The investigators hypothesized that there is a great variability in this Ce that could be precisely explained by * Electroencephalographic (EEG) features available prior to induction of anesthesia * Cognitive performance * Patients characteristics Participants will undergo preoperative cognitive testing and awake EEG. Then, induction of general anesthesia will be performed using continuous infusion of propofol. The Ce at which Deep anesthesia is observed will be recorded.
