The most frequent cause of vasodilatory shockis outcome from sepsis, a systemic inflammatory response to infection, characterized by hypotension, hyporeactivity to the catecholamines and disseminated intravascular coagulation. The commonest cause of sepsis has reported to be infection with Gram-negative bacteria, typically E. coli, resulting in the release of lipopolysaccharide (endotoxin) from the bacterial outer membrane during autolysis or death of these microorganisms, with the involvement of many mediators, including nitric oxide. Later it was found that plasma levels of vasopressin in sepsis patients were abnormally low and observed that some patients with advanced septic shock were extremely sensitive to the activity actions of exogenous vasopressin.
