This observational study aims to evaluate the relationship between the Pain Catastrophizing Scale (PCS) and intraoperative analgesia consumption in patients undergoing laparoscopic cholecystectomy. During the preoperative period, patients will complete the Pain Catastrophizing Scale, the Beck Depression Inventory, and the Beck Anxiety Scale. During the intraoperative period, analgesia nociceptive index (ANI) electrodes will be placed, and remifentanil dosing will be adjusted accordingly. The correlation between preoperative Pain Catastrophizing Scale scores and intraoperative remifentanil consumption will be analyzed.
