Catecholamine induced lactic acidosis after a laparoscopic resection of pheochromocytoma

ABSTRACT

Pheochromocytomas are catecholamine secreting tumors of the adrenal medulla, and most commonly originate from adrenal gland. Most tumors secret large amount of norepinephrine, and epinephrine to a lesser extent. The clinical presentations are due to the over activity of catecholamines. Classical presentations are paroxysmal or sustained hypertension with palpitations, headaches and profuse sweating. Both open and laparoscopic approaches are used for the tumor resection. Anesthetist pays a significant role in the peri-operative management. Hyperlactaemia and lactic acidosis can be complications of the surgery. This can have a significant impact on the outcome.
