The perioperative management of a patient with complex single ventricle physiology and pheochromocytoma

Pheochromocytoma is associated with intense physiologic effects of alpha- and beta-adrenergic stimulation from catecholamine secretion. Perioperative management for these patients includes alpha-adrenergic receptor blockade, intravascular volume replacement, and, if necessary, beta-adrenergic receptor blockade. Significant perioperative changes in preload and afterload, fluid status, heart rate and rhythm, and inotropy can occur and may be contrary to anesthetic management goals for patients with certain conditions of congenital heart disease. We report the perioperative management with doxazosin of a patient with single ventricle physiology and cavo-pulmonary and aorto-pulmonary lung perfusion. who presented for resection of a pheochromocytoma.
