The PATHFINDER Study: A Feasibility Trial (PATHFINDER)
Perioperative Multimodal General Anesthesia Focusing on Specific CNS Targets in Patients Undergoing Cardiac Surgeries
Přehled studie
Postavení
Podmínky
Detailní popis
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

Experimentální: 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.
