The Hemodynamic-Stabilizing Properties of Dexmedetomidine on Adrenalectomy For Pheochromocytoma: A Case Report

Abstract

Pheochromocytoma is a catecholamine-secreting neuroendocrine tumor and represents a challenge to the anesthesiologist. Without adequate preoperative preparation, excessive catecholamine release can result in life-threatening cardiovascular complications. To control blood pressure during the surgery, an infusion of sodium nitroprusside and dexmedetomidine was administered. Dexmedetomidine helps prevent hemodynamic instability during the tumor resection and was a way of interrupting the catecholamine release. This report attempts to address the preoperative and intraoperative issues in managing these challenging tumors with an emphasis on other therapeutic options to control the adrenergic crisis during the surgery.
