Background: Traditional anesthesia for cardiac surgery involved high opioid use associated with adverse events and poor outcomes which led to the adoption of multi-modal analgesic approaches. Although improvements in the overall opioid consumption are seen with multi- modal analgesic approaches, recent studies in opioid-sparing anesthesia and regional anesthesia can further reduce the operative use of opioids in cardiac surgery to improve patient outcomes. Methods: A comprehensive study search was conducted using CINAHL and MEDLINE (ProQuest) to identify research studies from the past three years that have focused on opioid- sparing anesthesia or opioid-free techniques in patients undergoing cardiac surgery with cardiopulmonary bypass.
Results: Six research studies were identified as relevant for review. The studies included in this literature review address opioid-sparing anesthesia in cardiac surgery through different techniques, investigate the feasibility for implementation, the role of regional anesthesia, and individual intraoperative pharmacological adjuvants in cardiac surgery requiring cardiopulmonary bypass (CPB).
