Summary
In this study the investigators plan to examine the perioperative use of sufentanil sublingual (SL) in the analgesic regimen for spine surgery, one of the most common surgeries performed in the US. Patients undergoing spinal fusion surgery often experience severe pain during the first three postoperative days. Currently, no data are available for this patient population which routinely experiences moderate to severe acute pain. The investigators will analyze whether sufentanil SL is associated with lower opioid consumption in the post anesthesia care unit and pain scores.
