【 摘 要 】

Phenoxybenzamine has traditionally been used to control the hypertension associated with pheochromocytomain children. However, doxazosin has been proposed as the alternative agent of choice, based upon the claimedability to effectively control perioperative hypertension with a single daily dose without the occurrence ofproblematic side effects sometimes associated with the use of phenoxybenzamine, e.g. the need for additionalβ blockers to control secondary tachycardia or vasopressors to correct resistant hypotension following tumorremoval.The perioperative course of two siblings, undergoing anesthesia for removal of extra-adrenal pheochromocytomas(paragangliomas) are compared. Doxazosin and phenoxybenzamine were used in their respective managementfor preoperative control of hypertension. The proposed benefits of doxazosin over phenoxybenzamine werenot observed and the intraoperative control of hemodynamics was significantly poorer with doxazosin. Theperioperative course of each sibling is compared and the published evidence supporting the use of doxazosin inchildren with pheochromocytoma is critically reviewed.
