  • Anisopoikilocytosis

    Peripheral smear showed moderate anisopoikilocytosis and presence of red cell fragments. Intravenous methylene blue was given in view of high suspicion of acute MetHb. [ijabmr.org]

  • Anisocytosis

    Peripheral blood smear showed normocytic, normochromic red blood cells that demonstrated polychromasia, anisocytosis, tear drop cells, and bite cells consistent with hemolysis. [amhsjournal.org]

Important factors in treatment are discussed. These include, gastric lavage, the administration of methylene blue and exchange transfusion. The possibility of a late haemolytic reaction being a complication of methylene blue treatment is mentioned. [unboundmedicine.com]

Methylene blue and exchange transfusion were the therapeutic methods applied in the treatment of the methemoglobinemia. Forty-eight hours after ingestion, a blood sample was collected in ICU and sent to our laboratory. [ncbi.nlm.nih.gov]
