Preserved Analgesia With Reduction in Opioids Through the Use of an Acute Pain Protocol in Enhanced Recovery After Surgery for Open Hepatectomy.

Background: Enhanced recovery after surgery (ERAS) pathways are designed to restore baseline physiology, mitigate surgical stressors, and hasten recovery. Paramount to this approach is optimal pain control through multimodal analgesia and limiting reliance on opioid-based medications. Recent studies have fostered growing controversy surrounding the use of epidural analgesia in the ERAS setting, especially for higher-risk procedures. We examine the analgesic end points associated with the use of epidural within the ERAS framework for open hepatectomy. Methods: From November 2013 through March 2016, postoperative analgesic end points including daily morphine equivalent administration and self-reported pain scores were prospectively collected and analyzed for 180 consecutive patients scheduled for open hepatectomy. Patients whose surgeries performed prior to July 2014 were managed using traditional strategy (pre-ERAS, n = 60), and those after July 1 underwent a comprehensive perioperative ERAS pathway (ERAS, n = 120). Results: Patients managed using the ERAS pathway had a significant reduction in morphine equivalent requirements at 24 hours (median, 10.0 vs 116.0 mg; P
