As such, they should be reserved for cases of persistent hypotension and tissue hypoperfusion after volume resuscitation has failed. Most vasopressors have multiple actions on the heart and vasculature and have a propensity to cause arrhythmias. Some vasopressors are also inotropes and are used to improve cardiac output, particularly in patients with left ventricular pump failure or cardiogenic shock. Table 20-11,2,3 provides a summary of common vasopressor and inotropic agent doses, effects, and uses.
