Endotoxin, a lipopolysaccharide component of the outer membraneof gram-negative bacteria, is involved in the pathogenesis ofseptic shock, but it is unclear whether endotoxin alone is capableof causing all the manifestations of the septic shock syndrome.In animals, endotoxin causes many of the clinical features1but produces a low-cardiac-output form of shock that is unlikethe hyperdynamic cardiovascular profile of septic shock in humans2,3.In humans, the administration of endotoxin (4 ng per kilogramof body weight) triggers the release of cytokines,4 activatesthe coagulation and fibrinolytic systems,5,6 and causes a decreasein systemic vascular resistance and . . .
