A 51 year old female patient underwent resection of pheochromocytoma under general anesthesia. Thiopental sodium 250mg and succinylcholine 50 mg were used for endotracheal intubation, followed by N2O, O2 and ethrane for induction and maintenance. For the management of blood pressure during surgical amnipulation, we used sodium nitroprusside dripping. After tomor resection, blood pressure was controlled by dopamine dripping and intravenous lactated Ringer's solution. The patient tolerated anesthesia and surgery well despite the episodic hemodynamic changes. Although tolerated anesthesia and surgery well despite the episodic hemodynamic changes. Although specific anesthetic drugs have been recommended, we believe that optimal preoperative preparation, a gentle induction of anesthesia, and good communication between surgeon and anesthesiologist are most important for anesthetic management.
