Target-Controlled Infusion and Postoperative Neurocognitive Outcomes in Geriatric Patients

This prospective observational study aims to evaluate the effects of target-controlled infusion (TCI) on postoperative neurocognitive function in geriatric patients undergoing major non-cardiac surgery. Elderly patients are at increased risk of postoperative cognitive dysfunction due to physiological changes and anesthesia-related factors. In this study, sedation management with TCI will be compared to manual infusion. Neurocognitive function will be assessed at multiple time points using the Mini-Mental State Examination (MMSE), and sedation levels will be monitored with the Bispectral Index (BIS) and the Richmond Agitation-Sedation Scale (RASS). The study aims to provide insights into safer sedation practices and improved cognitive outcomes in elderly surgical patients.
