Is Dexmedetomidine the Agent of Choice in the Resection of Pheochromocytoma?


MRI of the abdomen demonstrated a hyperintense 2-cm nodule in the left adrenal gland on T2 weighted images, without evidence of extra-adrenal disease. According to The Rochester Epidemiology Project, 500 to 1600 cases are diagnosed in the United States every year.1 The preoperative preparation of the patient with a pheochromocytoma is extremely important and has focused on correcting the cardiovascular sequelae of excess catecholamine release by the tumor. [...] an infusion of magnesium sulphate was also used in this patient, and the authors speculated as to whether the decreasing catecholamine levels were attributed to DEX and/or magnesium sulphate.4 DEX is a novel, highly selective a-2 adrenergic agonist with sedative and analgesic properties.
