Brief summary
To explore the predictive value of Electroencephalography features in Perioperative Neurocognitive Disorders in patients undergoing cardiovascular surgery under general anesthesia
Detailed 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.

| The predictive value of preoperative Electroencephalography features in patients with postoperative cognitive dysfunction following cardiovascular surgery | 2025.08 | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The predictive value of preoperative Electroencephalography features in patients with postoperative delirium following cardiovascular surgery | 2025.08 | Postoperative delirium was assessed using the confusion assessment method or the confusion assessment method for the intensive care unit (CAM/CAM-ICU) . |
| Electroencephalography features in patients with postoperative delirium | 2025.08 | Electroencephalography was collected in delirium patients one week(7±2 days) after surgery. Postoperative delirium was assessed using the confusion assessment method or the confusion assessment method for the intensive care unit (CAM/CAM-ICU) . Preoperative and postoperative electroencephalography brain network-related indexes (such as cluster coefficient, small world index, etc.) in patients with postoperative delirium will be included in the analysis. |
