Catecholamine-secreting neuroblastoma in a 4-month-old infant: perioperative management.

Preoperative alpha- and beta-adrenergic receptor block with phenoxybenzamine and labetalol, the intraoperative course of a 4-month-old infant with neuroblastoma and elevated catecholamines causing sweating, hypertension, and tachycardia, are presented. We recommend determination of catecholamine levels and pretreatment with alpha-adrenergic and--if needed--beta-adrenergic receptor antagonists in infants with neuroblastoma and hypertension, tachycardia, or sweating.
