A team at the Ruijin Hospital, Shanghai, analyzed the intraoperative outcomes of patients with normotensive pheochromocytomas who underwent adrenalectomy between January 2003 and July 2011. Patients treated with the α-blocker doxazosin perioperatively (n = 38) were significantly more likely to require the use of vasoactive drugs and colloid fluid during surgery than patients who did not receive doxazosin (n = 21), with no significant differences in intraoperative blood pressure and heart rate between groups.
