Mesenteric ischemia is a severe condition associated with abdominal pain which often requires multimodal analgesia, including opioids or sympathetic blocks such as celiac plexus blocks. The erector spinae plane (ESPB) has emerged as a potentially effective alternative for managing pain in various surgical and non-surgical conditions. This case report explores the use of ultrasound-guided ESPB as a novel approach to pain management in a patient with acute on chronic mesenteric ischemia. A 70-year-old male with a history of mesenteric ischemia and multiple comorbidities presented with worsening diffuse abdominal pain. Despite medical and surgical treatment, the patient required a high dose of opioids for pain control. Bilateral ESPBs with continuous infusions were performed at the T6 level under ultrasound guidance. The patient reported immediate and complete relief from abdominal pain following the block, with a significant drop in the pain score. The use of opioids was significantly reduced. This case report demonstrates the potential benefits of ultrasound-guided ESPB as an alternative to traditional pain management techniques in patients with mesenteric ischemia. ESPB may provide safe, simple, and effective analgesia, reducing the need for high-dose opioids and their associated side effects. Further studies are warranted to validate these findings and explore the broader application of ESPB in the management of mesenteric ischemia pain.
