Monitoring brain oxygen levels to understand postoperative delirium in carotid 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 observational study investigates the relationship between local cerebral oxygenation and the occurrence of postoperative delirium in patients undergoing carotid endarterectomy. It utilizes near-infrared spectroscopy (NIRS) to continuously monitor cerebral oxygen saturation during surgery, aiming to identify how fluctuations in oxygen levels may correlate with delirium post-surgery. The study will track patients' oxygen levels intraoperatively and collect postoperative data to establish a threshold for predicting delirium. This approach focuses on a high-risk group of elderly patients with various vascular risk factors.
