Early multiple organ failure after recurrent endotoxemia in the presence of vasoconstrictor-masked hypovolemia*

Abstract

Hypovolemia can be masked when volume status is monitored by filling pressures. In this new model of endotoxemia-associated multiple organ failure, chronic vasoconstrictor-masked hypovolemia turned systemic inflammation into a life-threatening condition with renal and cardiovascular failure. Cardiomyocyte necroses were caused by vasoconstrictor-masked hypovolemia but were unrelated to cardiovascular failure.
