Comparison of the Postoperative Analgesic Effects of ITM and Bi-level ESPB in Liver Transplantation Donors

Liver transplantation is a life-saving procedure for patients with end-stage liver disease, and postoperative pain management is critical for optimizing donor recovery and overall outcomes. Poorly controlled pain following donor hepatectomy may reduce quality of life, delay mobilization, and contribute to the development of chronic pain syndromes. Regional anesthesia techniques, such as intrathecal morphine and erector spinae plane block, have been utilized to enhance postoperative analgesia and reduce perioperative opioid requirements, potentially minimizing opioid-related adverse effects. In this study, we aimed to compare the postoperative analgesic efficacy of intrathecal morphine and Bi-level erector spinae plane block in living liver donors.
