Perioperative Multimodal General AnesTHesia Focusing on Specific CNS Targets in Patients Undergoing carDiac surgERies - the PATHFINDER II Study

The investigators propose to randomize (1:1) 70 patients undergoing cardiac surgery to the perioperative EEG-guided MMGA bundle (described in full below) or standard-of-care management based primarily on the use of sevoflurane for unconsciousness and intermittent doses of fentanyl and hydromorphone for antinociception.

The team will test the intraoperative EEG-guided MMGA management strategy in combination with a postoperative protocolized analgesic approach to ensure hemodynamic stability and decreased use of vasopressors in the operating rooms and reduce pain and opioid consumption postoperatively. The team will also investigate whether EEG-guided MMGA strategy reduces the incidence of perioperative neurocognitive dysfunction in cardiac surgical patients. This approach will further individualize care and minimize the use of intraoperative vasopressor-inotropic dose, dose of anesthetic medications, and postoperative opioids given to each patient potentially preventing hemodynamic complications and post-operative cognitive dysfunction after surgery.
