A Case of Portal Vein Gas Embolism from Hydrogen Peroxide Ingestion / 대한내과학회지

We present a case of a 19-year-old male with portal vein gas embolism resulting from accidental ingestion of 35% hydrogen peroxide. Hydrogen peroxide is a commonly used germicidal cleansing agent. When it is applied to tissues, catalase causes its rapid molecular decomposition with the release of oxygen bubbles. The patient recovered without sequelae. Hyperbaric oxygenation may be of benefit in patients with respiratory compromise or central nervous system symptoms from gas embolism in hydrogen peroxide ingestion.
