This case report described the perioperative management of a patient underg
oing laparotomy for ileal carcinoid tumor with liver metastases and preoper
ative carcinoid syndrome. During surgery, bispectral index monitoring, comb
ined with classical blood pressure and heart rate, allowed to discriminate
hypertension related to the carcinoid syndrom, from hypertension reflecting
an inadequate level of anaesthesia. Consequently, adequate treatment by a
somastotatin analogue could be early administered. (C) 2000 Editions scient
