—Dopamine is a common drug used in the emergency department and intensive care unit settings. Previously reported cutaneous complications have included local skin necrosis due to extravasation at the site of the intravenous canula, 1 and acral gangrene due to distal vasoconstriction leading to ischemia.2I report an unusual local cutaneous reaction proximal to the site of dopamine infusion.
Report of a Case.
—A previously healthy 27-year-old man was admitted to the coronary care unit with congestive heart failure due to idiopathic cardiomyopathy. A dopamine infusion at 5 to 7 μ/kg per minute was begun through a peripheral intravenous line in the left cephalic vein just above the wrist. Approximately 2 hours later, the patient noted an asymptomatic "rash" on the lateral side of the left upper arm, midway between the elbow and the shoulder.
