Management of blood pressure in children with pheochromocytoma and other catecholamine-secreting tumors (CSTs) is unique and challenging. The authors report a single-center experience using sequential α-adrenergic blockade (phenoxybenzamine), increased fluid intake, and β-blockade for presurgical management of 10 CSTs in children. In this retrospective review, mean duration for blood pressure control in preparation for surgery was 4.5±2.6 weeks. Intraoperative hypertension was noted transiently (<2 hours) in eight patients (80%) and was treated with continuous infusion of short-acting antihypertensive agents. Two (20%) patients required vasopressor medication infusion to manage intraoperative hypotension. Only two (20%) patients developed postoperative hypotension and required vasopressor medication infusion for <24 hours. All antihypertensive medications were discontinued in the immediate (≤4 days) postoperative period in 80% of patients. In conclusion, a systematic and multidisciplinary approach utilizing adrenergic blockade is effective in treating children with CSTs.
