High-Dose Vitamin B12 in Vasodilatory Shock: A Narrative Review

Jayshil J Patel et al. Nutr Clin Pract. 2019 Aug.

Abstract

Vasodilatory shock, as observed in postoperative states and sepsis, is hallmarked by low systemic vascular resistance and low blood pressure compensated by increased cardiac output. Gasotransmitters, such as nitric oxide and hydrogen sulfide, are implicated in the development and perpetuation of vasodilatory shock. Established therapies do not target these physiologic drivers of vasodilation. Due to their nontoxic and pleotropic effects, micronutrients are being used as rescue therapy in postoperative vasoplegia and septic shock. Here, we outline the pathophysiology of vasodilatory shock, describe the rationale for vitamin B12 (hydroxocobalamin) in vasodilatory shock, and identify literature evaluating its use in vasoplegic states.

Keywords: gasotransmitters; hydroxocobalamin; sepsis; shock; systemic vascular resistance; vasoplegia; vitamin B12.
