Paradoxical Cerebral Air Embolism Immediately after Ingestion of 5% Hydrogen Peroxide

ABSTRACT

We report the case of a 58-year-old man who developed multiple cerebral infarctions after ingesting accidently a 5% hydrogen-peroxide detergent solution. A 3~5% hydrogen peroxide solution is commercially available as an oxidant and detergent. Neurologic examination of this patient revealed grade III weakeness in both upper and lower limbs and bilateral positive Babinski signs. CT and MRI revealed bilateral multiple brain infarctions in the anterior and the middle vascular territories. The likely mechanism of pathogenesis must be paradoxical cerebral air embolism. Decompression through Nasogastric tube and hyperbaric oxygenation therapy were used to treating this patient. In spite of our intensive care, the patient expired 21days after ICU admission.
