Use of magnesium sulphate as adjunctive therapy for resection of phaeochromocytoma

The intraoperative control of cardiovascular disturbances associated with the resection of phaeochromocytoma is traditionally achieved by the use of deep anaesthesia in conjunction with A and B blockers, calcium antagonists, nitroglycerine or sodium nitroprusside. We report the successful use of magnesium sulphate as adjunctive therapy in the control of the cardiovascular consequences associated with surgical resection of a phaeochromocytoma in a patient.
