Sufentanil SL Arm
Each patient received 30mcg of sufentanil SL prior to extubation in the operating room, and then as needed in the recovery room, guided by pain scores. Sublingual Tablet: sufentanil SL 30mcg administered sublingually to patients undergoing spine surgery before extubation and during recovery
IV Remifentanil Historical Arm
Each patient received intraoperative remifentanil and hydromorphone for postoperative pain
