Abstract

Methemoglobin has been developed after iron oxidation in hemoglobin. Increase in the concentration of methemoglobin causes loss of oxygen carrying capacity and cascade of aerobic oxidation impairment, metabolic acidosis and cyanosis.  Even though it is rare, it has potentially life threatening effects if neglected. Therefore, it must be recognized and corrected on time. Methemoglobinemia should be considered as one of differential diagnosis whenever low arterial oxygen saturation with preserved oxygen tension has no response to supplementary oxygen administration. In this paper, we reported a patient who developed methemoglobinemia with high dose nitroglycerin infusion during coronary artery bypass graft. He was treated with ascorbic acid.

Keywords: Methemoglobinemia, nitroglycerin, oximetry
