Abstract1 The circulatory effects of labetalol have been studied in 88 patients undergoing plastic surgery, 8 patients with carcinoma of the breast, 10 with carcinoma in the head and neck, and in 2 patients with phaeochromocytoma, each anaesthetized twice. 2 The use of labetalol intravenously produced hypotension and a bloodless operating field in patients undergoing plastic surgery and in those undergoing radical surgery for the removal of carcinoma. 3 Two patients with phaeochromocytoma pre-treated with oral labetalol before anaesthesia, had well controlled BPs and heart rates during surgery, although in one instance additional intravenous labetalol was required. 4 Pre-operative preparation of patients with phaeochromocytoma with labetalol seems to be simpler and safer than previous techniques involving drugs with separate alpha- and beta-adrenoceptor-blocking effects.
