Perioperative EEG-Monitoring and Postoperative Delirium in Patients Undergoing Cardiovascular Surgery

Recruiting now

Conditions studied: Delirium

In brief

Postoperative delirium is common in patients undergoing cardiovascular surgery and associated with poor outcomes. However the pathogenesis of postoperative delirium is poorly understood. Multichannel electroencephalogram is a recognized tool for identifying neurophysiologic states during anesthesia, sleep, and arousal. The aim of the current study is to evaluate the mechanisms and predictors of postoperative delirium in patients undergoing cardiovascular surgery using electroencephalogram.
