What this trial studies

This observational study aims to investigate the use of intraoperative electroencephalography (EEG) to diagnose postoperative neurocognitive disorders (PND), particularly postoperative delirium (POD), in patients undergoing non-cardiac surgery. The study focuses on patients aged 18 and older who are scheduled for intermediate or high-risk surgeries under general anesthesia. By utilizing advanced EEG analysis techniques, the researchers hope to identify neurophysiological changes that could indicate the onset of cognitive complications during surgery. The findings could lead to improved diagnostic criteria and better management of PND.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older scheduled for non-cardiac surgeries that are classified as intermediate or high risk.

Not a fit: Patients with a preoperative MMSE score below 20, a history of mental illness, or those undergoing neurosurgical procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the early diagnosis and management of neurocognitive complications, potentially improving patient outcomes and quality of life post-surgery.

How similar studies have performed: While the use of EEG in anesthesiology is well-established, the specific application for diagnosing postoperative neurocognitive disorders is relatively novel and has not been extensively tested in prior studies.
