Abstract

|
|
Sodium nitrite is commercially used as a coloring agent, food preservative, corrosion inhibitor and antifreeze. Ingestion of nitrite may cause methemoglobinemia. A 63-year old man was admitted due to dyspnea and cyanosis after having an instant cup noodle with contaminated water containing antifreeze unintentionally. As blood methemoglobin concentration was high, intravenous methylene blue was administered. His symptoms was relieved and blood methemoglobin concentration decreased from 62.1% to 9.9%. We report here on a case of methemoglobinemia occurred after ingestion of antifreeze containing sodium nitrite.
