Opioid Sparing Anesthesia for Adult Spinal Deformity… : Spine
an OSA regimen than those not having an OSA regimen. Summary of Background Data. There has been a tremendous focus on opioid overuse. Accordingly, OSA regimens are being introduced to reduce narcotic use. However, OSA has not been studied in the adult spine deformity population. Methods. Forty-three patients undergoing fusion of at least five levels in the thoracolumbar spine received OSA. They were matched to 43 patients who did receive an OSA regimen. We analyzed several metrics including blood loss, anesthesia time, postanesthesia care unit (PACU) pain scores, postoperative pain scores, complications, length of stay, and readmissions. Results. The OSA group had significantly lower pain scores both before transfer to (4.6 vs. 7.6, P=0.000) and after transfer from (4.2 vs. 6.2 P=0.002) the PACU. Opioid use was significantly lower in the OSA group (454 vs. 241 MMEs by POD4, P=0.022). Fewer patients required blood transfusion in the OSA (1 vs. 28, P=0.000) group. Fewer patients in the O
