The Analgesia Nociception Index (ANI) is a new method of identifying nociception-analgesia balance. In this study we investigate the correlation between the ANI/ numeric rating scale (NRS) values immediately before-after extubation. NRS values recorded in the post-anesthesia care unit, in a group of patients who underwent a laparoscopic cholecystectomy, with the aim to evaluate the potential use of ANI values in the prediction of postoperative pain levels.
