Abstract

A 52-year-old male accidentally ingested approximately 100 mL of 35% hydrogen peroxide (H2O2), resulting in the sudden onset of gastrointestinal and neurologic symptoms. Non-contrast abdominal CT revealed extensive portal venous gas and gastric pneumatosis. The patient was treated with hyperbaric oxygen therapy which resulted in complete resolution of symptoms. The case highlights the therapeutic value of hyperbaric oxygen therapy in the treatment of vascular gas embolism and mitigation of concentrated H2O2 ingestion toxicity.
