Anesthetic Experiences for Resection of Bilateral Pheochromocytoma: Two cases / 대한마취과학회지

ABSTRACT

We had experienced anesthetic management of two patients with bilateral pheochromocytoma. They had been treated with phenoxybenzamine for 4 weeks preoperatively. Anesthesia was managed with thiopental sodium for induction,enflurane-N2O-O2 for maintenance, vecuronium for muscle relaxation, and sodium nitroprusside for controlling severe hypertension. After tumor resection, severe hypotension was controlled by rapid transfusion, fluid and dopamine infusion. A tolerable blood pressure and pulse rate were maintained throughout the procedure. Preoperative preparation, sufficient sedation, smooth anesthetic induction, complete analgesia, good muscle relaxation, adequate ventilation and proper cardiovascular control are required in resection of pheochromocytoma.
