Pharmacology of Octreotide: Clinical Implications for Anesthesiologists and Associated Risks

Anesthesiol Clin. 2017 Jun;35(2):327-339. doi: 10.1016/j.anclin.2017.01.021.

Abstract

Many patients presenting with a history of foregut, midgut neuroendocrine tumors (NETs) or carcinoid syndrome can experience life-threatening carcinoid crises during anesthesia or surgery. Clinicians should understand the pharmacology of octreotide and appreciate the use of continuous infusions of high-dose octreotide, which can minimize intraoperative carcinoid crises. We administer a prophylactic 500-μg bolus of octreotide intravenously (IV) and begin a continuous infusion of 500 μg/h for all NET patients. Advantages include low cost and excellent safety profile. High-dose octreotide for midgut and foregut NETs requires an appreciation of the pathophysiology involved in the disease, pharmacology, drug-drug interactions, and side effects.

Keywords: Carcinoid crisis; Carcinoid syndrome; Octreotide; Sandostatin; Somatostatin.
