    ObjectivesTo assess the impact of intraoperative dexmedetomidine and ketamine on postoperative pain and opioid consumption within an ERAS program in thoracic pulmonary oncologic surgery.DesignRetrospective, propensity-score matched analysis SETTING: Enhanced Recovery After Surgery (ERAS) program.ParticipantsPatients undergoing thoracic pulmonary oncologic surgery between March 2016 and April 2020.InterventionsContinuous infusion of dexmedetomidine and ketamine.Measurements & Main ResultsThe authors initially analyzed data of 1,630 patients undergoing thoracic pulmonary oncologic surgery within their ERAS program. In total, 117 matched pairs were included in this analysis. Patients in the intraoperative dexmedetomidine + ketamine group were more likely to be opioid-free (76.6% vs 60.9%, P<0.01). Raw analysis showed lower pain scores at PACU admission (2.8±2.0 vs 3.4±2.0, P=0.03) and less opioid consumption at PACU admission (5 MED [0-10] vs 7.5 MED [0-15], P=0.03) in the dexmedetomidine + ketamine group; however, these differences were not present after adjusting for multiplicity. There were no significant differences in the length of PACU stay (1.9 hours [1.5-2.8] vs 2.0 hours [1.4-2.9], P=0.48) or hospital stay (three days [two-five] vs three days [two-five], P=0.08). Both groups had similar rates of pulmonary complications (5.9% vs 9.4%, P=0.326), ileus (0.9% vs 0.9%, P=1.00), and 30-day readmission (2.6% vs 4.3%, P=0.722).ConclusionsThere were no differences in postoperative pain scores and opioid consumption throughout their hospital stay between patients receiving concomitant dexmedetomidine and ketamine infusions versus patients who did not receive these infusions during thoracic surgery.Copyright © 2021 Elsevier Inc.
