An anesthetic experience with bilateral adrenalectomy for pheochromocytoma in an 18 year old male has been reported. We chose fluothane as a primary anesthetic agent for the management of anesthesia 'with relative satisfaction. The patient was treated with phenoxybenzamine for a long time (about 40 days) and also with propranolol for a few days intermtteently before induction of anesthesia. During anesthesia and operation, the highest systolic blood pressure was 180 mmHg, the lowest was 80 mmHg and some variable arrhythmias with extrasystoles were present. But these were well controlled immediately after administration of regitine and propranoloL Recently some reviews of the literature on the anesthetic management of pheochromocytoma suggest that the selection of an anesthetic agent is not as important as the adequate management of the characteristics of those agents which affect the anesthetic procedures. Conclusively, we prefer to recommend that it is important to manage the patients with α & β-adenergic blocking agents for at least several weeks pre-operatively, and to use the anesthetic agents as far as possible which do not have the sensitizing effects to catecholamine on myocardium.
