Perioperative α-receptor blockade in phaeochromocytoma surgery: an observational case seriesâ€

Only a slight difference in mean maximal systolic arterial pressure was detected between patients with or without an α-receptor blockade. There was no difference in the incidence of excessive hypertensive episodes between groups and no major complications occurred. The basis for the general recommendation of perioperative α- receptor blockade for phaeochromocytoma surgery demands further study.
