Herbicide-Induced Methemoglobinemia Presenting with Cyanosis and Hypoxemia: A Rare Case Report
Dr. V. V. Deepak [2] | Dr. D Srinivasa Raju
Abstract: Methemoglobinemia, a rare condition characterized by the presence of methaemoglobin in the blood, can result from exposure to certain chemicals, including herbicides. Methemoglobinemia occurs when red blood cells (RBCs) contain methaemoglobin at levels higher than 1%. Methaemoglobin results from the presence of iron in the oxidized ferric form (Fe3+) instead of the usual reduced ferrous form (Fe2+). This results in a decreased availability of oxygen to the tissues. This condition can be congenital or acquired. We present a case of a 47-year-old male patient with no significant past medical history, who presented to the hospital with high-grade fever, weakness, cyanosis, and hypoxemia following recent herbicide exposure.
