Postoperative Benefits of Intraoperative Nociception Level (NOL) Titration - Pilot

Previous work has shown that NOL (Medasense, Ramat Gan, Israel) accurately quantifies nociception during general anesthesia. Presumably, titrating opioids to NOL will therefore provide individual guidance so that patients will be given about the right amount. Patient given the right amount will presumably awaken quickly when anesthesia is done, and have good initial pain control in the post anesthesia care unit (PACU). To the extent that NOL titration facilitates optimal opioid dosing, patients are likely to have better PACU experiences - which would be an important outcome that clinicians and regulators are likely to take seriously.
