Correlation of the surgical pleth index with the postoperative pain in laparoscopic cholecystectomy an observational study

This prospective cross-sectional observational study titled Correlation of the Surgical Pleth Index with Postoperative Pain in Laparoscopic Cholecystectomy aims to examine the relationship between intraoperative Surgical Pleth Index (SPI) values recorded at six specific timepoints during elective laparoscopic cholecystectomy under general anesthesia and postoperative pain intensity. The primary objective is to assess whether intraoperative SPI levels correlate with postoperative pain scores. Secondary objectives include evaluating how demographic factors (age), duration of surgery, comorbidities, and intraoperative analgesic use influence this correlation. There is a notable gap in the literature, as no prior studies have assessed SPI at multiple intraoperative intervals in this surgical context. The findings could inform perioperative pain assessment and individualized analgesic strategies in a routinely performed surgical procedure
