Optimizing Recovery in Cardiac Surgery: A Narrative Review of Enhanced Recovery After Surgery Protocols and Clinical Outcomes

Enhanced Recovery After Surgery (ERAS) is an evidence-based, holistic perioperative recovery protocol intended to improve patient outcomes and decrease postoperative complication rates. While ERAS protocols were first introduced in 1997, specific guidelines for cardiac surgery were not established until 2019. Although the core principles of ERAS remain constant across surgical disciplines, ERAS guidelines for cardiac surgery have remained relatively understudied, likely due to the unique complexities posed by cardiac procedures. Within this comprehensive narrative review, we aimed to explore the current guidelines and evidence for ERAS in both cardiac and non-cardiac surgeries. In non-cardiac surgeries, ERAS has been shown to improve various outcomes, including ICU length of stay, patient satisfaction, and pain management. ERAS for cardiac surgery has also shown encouraging results, including shorter ICU and hospital stays, reduced postoperative opioid use, and faster recovery times. However, there is limited consensus across studies, particularly regarding its impact on morbidity and mortality, with mixed results reported. Furthermore, the limited data on the efficacy of ERAS in minimally invasive cardiac surgeries makes it difficult to establish well-supported guidelines for these procedures. Despite its limitations, the overall outcomes of ERAS for cardiac surgery remain promising. As our understanding and application of ERAS in cardiac surgery continue to evolve, these protocols have the potential to redefine cardiac surgical care standards.
