MRI of the spine requires the patient to stay still in lying down position. With patient on severe excruciating pain, lying down supine is not always feasible during MRI and any intervention with least possible adverse effect on the patient is preferred. Sedation in MRI suite requires MRI compatible monitors which is not readily available in all centers. The erector spinae plane block provides analgesia via its action on the ventral rami of spinal nerves. ESP block is a safe and easy procedure and it aids to overcome the side effects of administering intravenous agents for procedural sedation.

Subcutaneous emphysema (SE) following general anesthesia though a rare and benign entity, however if extensive can cause tremendous patient discomfort. Development of post operative SE cannot be simply ignored and may indicate possible grave injuries like injury to the airway that might require prompt recognition and management. We report a rare case of postoperative SE after an emergency laparotomy surgery, secondary to an uncommon iatrogenic cause.
