1/1. Pseudomethemoglobinemia: a case report and review of sulfhemoglobinemia.OBJECTIVES: To see if methemoglobin could potentially be misdiagnosed and the limitation of present cooximeters. PATIENT: A 17-year-old girl who overingested a combination of cimetidine, acetaminophen, ibuprofen, and naproxen in a suicide attempt. METHOD: Use of pulse co-oximeters to aid in the diagnosis of suspected sulfhemoglobinemia. RESULTS: diagnosis of sulfhemoglobinemia achieved with final confirmation made with gas chromatography. Patient steadily improved with supportive care. CONCLUSIONS: There is a potential for the diagnosis of methemoglobin with some of the limitations of present co-oximeters. The laboratory diagnosis of sulfhemoglobinemia can be difficult to make.- - - - - - - - - - ranking = 1keywords = chromatography (Clic here for more details about this article) |
