Opioid-Sparing Cardiac Anesthesia: Secondary Analysis of an Enhanced Recovery Program for Cardiac Surgery

Abstract

Nonopioid interventions employed as part of an ERP for cardiac surgery were associated with a reduction of intraoperative opioid administration. Low and ultralow opioid use was not associated with significant differences in postoperative outcomes. These findings are hypothesis-generating, and future prospective studies are necessary to establish the role of opioid-sparing strategies in the setting of cardiac surgery.
