This document provides an overview of vasopressors and inotropes used in critical care to treat shock. It discusses the different types of shock and principles of resuscitation including fluid administration and optimization of oxygen delivery and consumption. It also reviews the mechanisms of action, indications, and side effects of commonly used vasopressors and inotropes like dopamine, dobutamine, milrinone, levophed, phenylephrine, epinephrine, and vasopressin. Case studies are presented to demonstrate how these agents may be applied based on a patient's hemodynamic status.
