Erector Spinae Plane Block for Post-Operative Analgesia for Above the Knee Amputation: A Case Report

Abstract Background: Above the knee amputations (AKA) are common surgeries that frequently use neuraxial or peripheral nerve blocking techniques for both intraoperative and postoperative analgesia. It is not uncommon that patients present with contraindications to neuraxial anesthesia. Case presentation: We identified a relatively novel use of erector spinae plane block (ESP) for above the knee amputation that allows for adequate pain control postoperatively when there are contraindications for neuraxial. Conclusion: While data on ESP at the thoracic level is well described, less is known about the expected coverage for lumbar ESP. This case suggests that at the level of L3 there is sufficient dermatomal spread for an AKA.
