Erector spinae plane block for postoperative analgesia for above-the-knee amputation: a case report

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.
