Analgesia Nociception Index, ANI
Brief summary
The aim of this study is to evaluate the performance of Analgesia/Nociception Index (ANI) measured at the end of surgery for the prediction of immediate postoperative pain in postoperative care unit in adult patients undergoing general anesthesia.
Detailed description
Assessment of the performance of ANI to predict immediate postoperative pain on a 0-10 numerical rating scale (NRS) \>3 by building a receiver operating characteristic curve.
