Abstract
We report an 81-year-old man who was brought to the emergency department (ED) after drug intoxication. Due to unstable vital signs, prompt intubation was performed. During MRI examination, he became irritable, and became semicomatose. CPR was performed and return of spontaneous circulation occurred after 15 minutes of CPR. Follow-up chest radiography showed severe subcutaneous emphysema and pneumomediastinum. His vital signs were still unstable and he was transferred to the operation room for laparotomy. On exploration, retroperitoneal emphysema and air bubbles in the mesentery and omentum were noted. No visceral perforation was found. The postoperative course was uneventful he was discharged home on the twenty-ninth postoperative day.
