Cause of methemoglobinemia: illness versus nitrate exposure.
To the contrary, the information presented by Knobeloch et al. (1) support my conclusions (2). Knobeloch et al. (1) described two purported cases of infantile methemoglobinemia in their paper. The diagnosis of methemoglobinemia in case 1, however, is completely speculative: a doctor did not examine the infant, and blood methemoglobin concentrations were not measured during the observed anoxia. ...

Congenital methemoglobinemia is a rare cause of cyanosis. We report a case of a girl, 17 years old with peripheral cyanosis and normal cardio-pulmonary system. She was diagnosed as a case of methemoglobinemia based on findings of polycythemia and HbM band on hemoglobin electrophoresis.

In addition, hereditary methemoglobinemias ...
متن کاملMethemoglobinemia and Pulse Oximetry
In reviewing the article “Methemoglobinemia: Sudden Dyspnea and Oxygen Desaturation After Esophagoduodenoscopy,” in the August 2004 issue of RESPIRATORY CARE,1 I found the article suggested that, during the esophagoduodenoscopy procedure the patient’s blood oxygen saturation (measured via pulse oximetry) began to drop rapidly, and a saturation of 54% registered on the pulse oximeter while the p...
