Ankle block represents a regional anesthesia technique to provide anesthesia for the procedures related to the foot. It is mainly used as a sole anesthesia technique or as an adjunct for postoperative pain relief in foot operations. It is an infiltrative block with advantages like being technically easier, safe, having minimal side effects, and having a high success rate. Management of postoperative pain is an essential service provided by a cardiac anesthesiologist to patients undergoing operative procedures, but the knowledge in providing regional anesthesia may be used beyond the operating room or critical care unit. In the present case, we administered an ankle block to alleviate the pain in case of dry gangrene.
