Methemoglobinemia

The American Journal of the Medical Sciences, 1985
Oxygen transport, the major function of hemoglobin, is dependent upon reduced heme iron. In the red cell, the heme iron is maintained in the reduced form by the methemoglobin reduction system. When the balance between oxidation and reduction of heme iron is perturbed due to the presence of excessive oxidants, decreased reducing capacity or the presence

Methemoglobinemia

Southern Medical Journal, 2011
The diagnosis of methemoglobinemia should be considered in patients presenting with cyanosis and hypoxia. A variety of frequently used medications are capable of inducing methemoglobinemia, with dapsone and benzocaine being common culprits. Unique features, such as a saturation gap and chocolate-brown-colored blood, can raise suspicion for ...

Methemoglobinemia and Sulfhemoglobinemia

New England Journal of Medicine, 1948
THE appearance of severe cyanosis may alarm the patient and presents a diagnostic problem to the attending physician. Recognition of the cause of the cyanosis and the specific blood pigment involved permits the separation of conditions connoting serious underlying disease from those of benign origin. An increased amount of reduced hemoglobin in cardiac

Methemoglobinemia

American Journal of Hematology, 1993
AbstractThe ferrous iron of hemoglobin is exposed continuously to high concentrations of oxygen and, thereby, is oxidized slowly to methemoglobin, a protein unable to carry oxygen. To restore hemoglobin function, methemoglobin (ferrihemoglobin) must be reduced to hemoglobin (ferrohemoglobin).
