Monitoring brain activity to understand delirium after heart surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study investigates the occurrence of postoperative delirium in patients undergoing cardiovascular surgery by utilizing multichannel electroencephalogram (EEG) monitoring. It aims to identify the mechanisms and predictors of delirium through the analysis of neurophysiological states during anesthesia and recovery. By assessing patients' brain activity, the study seeks to enhance understanding of how delirium develops in this population. The research focuses on patients with normal cognitive function who are fluent in Chinese Mandarin.
