Comparison of Target-Controlled Infusion Using the Eleveld Model and Manual Total Intravenous Anesthesia on Intraoperative Anesthetic Consumption and Postoperative Pain and Delirium in Supratentorial Surgery
This study aims to investigate the effect of target-controlled infusion using the Eleveld pharmacokinetic model compared with manually controlled total intravenous anesthesia on the incidence of postoperative delirium in patients undergoing supratentorial surgery. Propofol and remifentanil are administered using either target-controlled or manual infusion techniques according to the study protocol. Secondary objectives include comparisons of intraoperative anesthetic consumption, hemodynamic responses, recovery profiles, postoperative pain, and postoperative nausea and vomiting between the two anesthesia strategies. The study seeks to evaluate whether target-controlled infusion provides improved anesthetic management and postoperative outcomes compared with manual total intravenous anesthesia.
