Overview
To explore the predictive value of Electroencephalography features in Perioperative Neurocognitive Disorders in patients undergoing cardiovascular surgery under general anesthesia
Description
Data was acquired on the ward using a 10-20 system with a standard 32-channel EEG cap and an EEG instrument (BP Company, Gilching, Germany). Patients were tested using cognitive assessment scales before and after surgery.
Cognitive levels were assessed 1 day before surgery and 1 week after surgery (7±2 days) using the Montreal Cognitive Assessment (MoCA) . Patients were followed up one month (30±2 days) after surgery using the Telephone version of the Montreal Cognitive Assessment Scale (T-MoCA).
Preoperative and postoperative electroencephalography brain network-related indexes (such as cluster coefficient, small world index, etc.) in patients with PND will be included in the analysis.
