RESUMEN
We have experienced an anesthetic management of a 34 year old female patient with pheochromocytoma of left adrenal gland. The anesthetic management of patients presents many difficult problems, such as hypertension, arrhythmia and hypotension. The patient had been treated with phenoxybenzamine for 2 weeks preoperatively. Following induction of anesthesia with intravenous fentanyl, thiopental sodium and vecuronium, endotracheal intubation was performed. Anesthesia was maintained with nitrous oxide, oxygen and isoflurane administration. Blood pressure and pulse were controlled well with nitroprusside and isoflurane. After removal of tumor, blood pressure was controlled by Hartman's solution, packed red cell and dopamine administration. The patient tolerated well despite the episodic hemodynamic changes. Importance of preoperative preparation, sufficient sedation, smooth induction, complete analgesia, good muscle relaxation and stable cardiovascular control has been discussed.

Local or general anesthesia is essential for safe operation. Patients in good preoperative condition are relatively to tolerable to the operation, but the patients in poor preoperative condition have the high mortality and morbidity during and after the operation. Therefore, we should choose the anesthetic agents and methods, which cause little effect to the patient's life. Among the intraventricular blocks, bundle branch is the most common type, and left bundle branch block may progress to a more serious condition of complete heart block. Optimal anesthetic management of patients with cardiovascular disease requires a thorough knowledge of normal cardiac physiology, the circulatory effects of the various anesthetic agents, and the pathophysiology and treatment of these diseases. The authors successfully performed balanced anesthesia in operation of a 63 year old female patient who showed complete left bundle branch block pattern in a preoperative electrocardiographic tracing without any subjective symptoms.
