Preoperative Pain Catastrophizing and Intraoperative Analgesia Consumption

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.

Treatment and study plan

Primary outcomes

  1. Intraoperative remifentanyl requirement

    Time frame: Intraoperative period

    The main purpose of this study is to evaluate the correlation between preoperative Pain Catastrophizing Scale and intraoperative analgesia consumption.Intraoperative analgesic dose is adjusted according to the analgesia nociceptive index.

Secondary outcomes

  1. Numeric rating scale for postoperative pain intensity

    Time frame: up to 24 hours

    Changes in Numeric Rating Scale (NRS) at rest and on movement will be recorded at intervals. NRS is a unidimensional measure of pain intensity in adults. The NRS is a segmented numeric version of the visual analog scale in which a respondent selectsand its correlation with the preoperative PCS score will be investigated.
