Trial Design

4Treatment groups
Experimental Treatment
Active Control
Group I: Maintenance-Alpha Optimization / Wake from PropofolExperimental Treatment2 Interventions
During the first randomization, participants randomized to intraoperative oscillatory EEG alpha optimization will receive individualized titration of anesthetic gas and opioid. During the second randomization, participants randomized to conversion to a propofol infusion for emergence from anesthesia will received an infusion of propofol 400mg/h and simultaneous reduction of desflurane concentration during the final 10-20 minutes of surgery.
Group II: Maintenance-Routine Care / Wake from VolatileActive Control1 Intervention
During the first randomization, participants randomized to standard of care will receive anesthesia per usual care with quantitative processed EEG index values and EEG wave forms. During the second randomization, participants randomized to standard emergence from volatile anesthesia will be woken up per standard practice.
Group III: Maintenance-Routine Care / Wake from PropofolActive Control1 Intervention
During the first randomization, participants randomized to standard of care will receive anesthesia per usual care with quantitative processed EEG index values and EEG wave forms. During the second randomization, participants randomized to conversion to a propofol infusion for emergence from anesthesia will received an infusion of propofol 400mg/h and simultaneous reduction of desflurane concentration during the final 10-20 minutes of surgery.
Group IV: Maintenance-Alpha Optimization / Wake from VolatileActive Control1 Intervention
During the first randomization, participants randomized to intraoperative oscillatory EEG alpha optimization will receive real-time monitoring of alpha recordings and individualized titration of desflurane and opioid. During the second randomization, participants randomized to standard emergence from volatile anesthesia will be woken up per standard practice.
