    Abstract:
    We used a Swan-Ganz catheter with a fast-response thermistor to measure the right ventricular ejection fraction (RVEF) during the anesthetic management of two patients with epinephrine-dominant pheochromocytomas. Pre-operatively, one patient received alpha adrenergic blocking agents (prazocine, doxazocine) to control the blood pressure but the other patient did not receive any agents. In the latter patient who did not receive alpha adrenergic blocking agents, right ventricular function was depressed post-operatively in the recovery room. The importance of preoperative preparation with alpha adrenergic blocking agents was confirmed by the reductions in RVEF and RVEDVI (right ventricular end-diastolic volume index) after resection of the tumor. Not only left heart monitoring but also right heart monitoring with RVEF and RVEDVI are recommended for the proper management of a patient with pheochromocytoma.
