Abstract
Methemoglobinemia is an uncommon cause of cyanosis; however, rapid diagnosi s is critical to avoid potentially fatal consequences. Several local anesth etics can precipitate methemoglobinemia in susceptible patients. This case report of acute methemoglobinemia occurred during fiberoptic intubation in an awake patient without a past medical history of adverse reactions to loc al anesthetics.
