Processed Electroencephalography-guided General Anesthesia and Outcomes in Major Abdominal Surgery

"Processed electroencephalography (pEEG) can guide the optimization of anesthesia depth, potentially preventing overly deep anesthesia and, in turn, reducing the incidence of IOH and the need for vasopressors .~Depth of anesthesia will be managed based on pEEG monitoring using Entropy with a target range of 40-60."

Depth of anesthesia will be managed based on clinical judgment, informed by clinical perception and vital signs.
