Descriptor metahemoglobinemia
Scope note: Presencia de metahemoglobina en la sangre, lo que produce cianosis y dolor de cabeza, vértigo, agotamiento, ataxia, disnea, taquicardia, náuseas, vómitos, somnolencia, estupor, coma y (en raras ocasiones) la muerte. Puede ser de origen químico o inducida por fármacos, o deberse a una irregularidad en la hemoglobina M (un rasgo autosómico dominante) o a una insuficiencia de la enzima reductasa del citocromo-b5 (un rasgo autosómico recesivo).

Scope note: The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)
