Evaluation of the Intraoperative Perfusion Index for Correlation with Acute Postoperative Pain in Patients Undergoing Laparoscopic Colorectal Cancer Surgery.

Despite technical advancements in the perioperative management of cancer surgery, postoperative pain remains a significant clinical issue. We examined the diagnostic value of the intraoperative perfusion index for predicting acute postoperative pain in patients undergoing laparoscopic colorectal cancer surgery. We retrospectively analyzed data for 105 patients who had undergone laparoscopic colorectal cancer surgery.
