Shock syndromes are associated with unacceptably high rates of mortality in critically ill patients despite advances in therapeutic options. Vasodilatory shock is the most common type encountered in the intensive care unit. It is manifested by cardiovascular failure, peripheral vasodilatation, and arterial hypotension leading to tissue hypoperfusion and organ failure. Hemodynamic support is typically initiated with fluid resuscitation strategies and administration of adrenergic vasopressor agents in fluid nonresponsive patients to restore arterial pressure with subsequent adequate organ reperfusion. Unfortunately, high catecholamine dosing requirements may be necessary to achieve targeted hemodynamic goals, which may increase the risk of vasopressor-induced adverse events. The purpose of this article is to review the clinical efficacy and safety data and potential role in therapy for catecholamine-sparing agents in vasodilatory shock. Adjunctive therapeutic options to reduce vasoactive support requirements without compromising arterial pressure include arginine vasopressin and analogues, corticosteroids, midodrine, methylene blue, and angiotensin II. Although concomitant vasopressin and corticosteroids have a more defined role in evidence-based guidelines for managing shock, clinicians may consider other potential catecholamine-sparing agents.
