Preoperative Epidural Infusion for Blood Pressure Control in Phaeochromocytoma

Abstract

The 2004 World Health Organization (WHO) classification of endocrine tumours defines phaeochromocytoma as a catecholamine-producing intra-adrenal tumour arising from the chromaffin cells. The most important functional characteristics of the adrenal and extra-adrenal sympathetic tissue derived tumours is the production of various types of catecholamines and the related clinical attributes [1]. Preoperative blood pressure control in phaeochromocytoma is an uphill task using multiple medications leading to post operative hypotension. It is well known that complete prevention of perioperative hypertension and tachycardia cannot be achieved by any dose or combination of drugs. Epidural anesthesia is often used for pain control in open resection of these tumours; one of its side effects is hypotension [2]. We describe here a case of phaeochromocytoma in whom perioperative blood pressure control was achieved with the help of epidural drugs instead of systemic antihypertensive medications.
