Naphthalene Toxicity: Methemoglobinemia and Acute Intravascular Hemolysis

Methemoglobinemia and intravascular hemolysis in a patient with G6PD deficiency.

Unexpected Intravascular Hemolysis and Methemoglobinemia during Treatment for Lymphoma

A patient undergoing chemotherapy for relapsed non Hodgkin lymphoma developed tumor lysis syndrome, hypoxia and the abrupt onset of intravascular hemolysis. A past history of unexplained anemia and the finding of blister cells on peripheral smear led to the suspicion of congenital glucose phosphate dehydrogenase (G6PD) deficiency with intravascular hemolysis induced by the drug rasburicase. G6P...

Methemoglobinemia, Heinz bodies, and acute massive intravascular hemolysis in lysol poisoning.

Intravascular and Extravascular Hemolysis Accompanying Extracorporeal Circulation

Eleven patients undergoing open heart surgery were studied by means of a technic previously developed by us to quantitate intravascular and extravascular hemolysis. Endogenous production of carbon monoxide, which correlates quantitatively with red blood cell and hemoglobin catabolism, was measured preoperatively, 5 hr postoperatively, and 24 hr postoperatively. Rates of plasma hemoglobin catabo...

Acute methemoglobinemia after endoscopy.

Acute methemoglobinemia may be caused by topical anesthetics and other oxidizing medications commonly prescribed by Family Physicians. Without knowledge of this potentially lethal condition, delay in diagnosis and treatment is likely. Methemoglobinemia should be considered in any patient presenting with cyanosis, particularly after the use of oxidizing medications. We describe a case of methemo...
