Acute methemoglobinemia during cardiopulmonary bypass caused by intravenous nitroglycerin infusion
F Robicsek
The case of a patient is presented who was undergoing coronary bypass
grafting and who, during cardiopulmonary bypass, became severely cyanotic
because of methemoglobinemia after intravenous infusion of nitroglycerin.
His condition responded promptly and favorably to the withdrawal of the
offending agent and to administration of methylene blue.
