The PATHFINDER Study: A Feasibility Trial (PATHFINDER)
27 januari 2021 uppdaterad av: Balachundhar Subramaniam, Beth Israel Deaconess Medical Center
Perioperative Multimodal General Anesthesia Focusing on Specific CNS Targets in Patients Undergoing Cardiac Surgeries
The main purpose of this study is to determine whether a rational strategy of EEG guided multimodal general anesthesia using target specific sedative and analgesics could result in enhanced recovery after anesthesia and surgery, decrease in postoperative delirium, and decrease in long term postoperative cognitive dysfunction up to 6 months following cardiac surgery.

Detaljerad beskrivning
The main purpose of this study is to determine whether a rational strategy of EEG guided multimodal general anesthesia using target specific sedative and analgesics could result in enhanced recovery after anesthesia and surgery, decrease in postoperative delirium, and decrease in long term postoperative cognitive dysfunction up to 6 months following cardiac surgery.
Specific Aim 1: The feasibility of implementing multimodal general anesthesia strategy in the Operating Rooms (OR) Specific Aim 2: The feasibility of implementing EEG guided sedation until extubation in the Intensive Care Unit (ICU) Specific Aim 3: The enhancement of recovery after surgery (shorter ventilation time, ICU stay, hospital length of stay) Specific Aim 4: To estimate the effect size of decrease in postoperative day (POD) and postoperative cognitive dysfunction (POCD) to power future large randomized trials

Experimentell: Multimodal General Anesthesia
Intraoperative The anesthesiologists involved in this study will be trained to infer differences in anti-nociception, unconsciousness movement and changes during other perioperative events by monitoring EEG. They will also be trained in titrating hypnotic and nociceptic medications based on changes in EEG.
Postoperative

Intraoperativ infusion
Intraoperativ infusion
Intraoperativ intermittent bolus
Intraoperativ infusion
Intraoperative bilateral PIFB block with 20 mL of 0.25% Ropivicaine on either side of the sternum after anesthetic induction but before surgical incision
Intraoperative inhaled as needed
Post-operative infusion

Övrig: Standard Practice with EEG monitoring
The initial 2 patients will receive standard anesthesia practice and perioperative EEG monitoring will be recorded to learn the patterns associated with our standard practice.

Incidence of Delirium
Tidsram: Participants will be followed for the duration of the hospital stay, an average of 5 days

Incidence of delirium will be analyzed in patients treated with the multi-modal approach.
Delirium will be defined as an acute change in pre-operative baseline condition with additional features of inattention and either disorganized thinking and altered loss of consciousness, as defined by the Confusion Assessment Method (CAM)Assessment Method (CAM) algorithm postoperatively until discharge.
