The use of magnesium sulfate in the anesthetic management of pheochromocytoma

Abstract

A case of pheochromocytoma is presented in which alpha- and beta-adrenergic blockers failed to provide adequate cardiovascular control. A preinduction infusion of 2.5 g of magnesium sulfate restored cardiovascular parameters to acceptable values. Further disturbances of cardiovascular function during tumor excision were well controlled with the use of magnesium sulfate and halothane as the only intraoperative antiadrenergic drugs.
