Inclusion Criteria: 1. Written informed consent 2. undergoing coronary artery bypass surgery or valve replacement surgery under general anaesthesia 3. ASA grade: II-IV 4. older than 60 years 5. Able to complete cognitive function tests Exclusion criteria: 1. history of severe neurological diseases and psychiatric diseases 2. history of drug abuse 3. severe hearing or vision impairment 4. preoperative delirium 5. serious adverse reactions such as cardiac arrest and cardiopulmonary resuscitation during surgery 6. patients undergoing secondary surgery in a short period 7. participation in concurrent clinical trials

Primary outcome measure(s)

  • 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).
