Abstract
Septic shock is characterized by major disturbances of vaso-regulation and oxygen transport DO2, resulting in maldistribution of blood flow in relation to tissue O2 demand, and consequently tissue hypoxia. The principal hemodynamic abnormality is widespread arteriolar vasodilatation, resulting in systemic hypotension, which is frequently compounded by hypovolemia caused by increased capillary permeability. Restoration of circulating volume leads generally to a clinical picture characterized by a normal or high cardiac index (CI) with a reduced systemic vascular resistance (SVR). There is now good evidence that the generalized vasodilation is caused, at least in part, by excess release from the vascular endothelium of nitric oxide (NO), the synthesis of which is induced by lipopolysaccharide (LPS) and cytokines such as tumour necrosis factor-α (TNF-α) and interleukin-1 (IL-1) [1]. Despite the high overall cardiac output and generalized vasodilation, the presence of flow-dependent oxygen consumption (VO2) at high levels of DO2 and of hyperlactatemia in many cases implies inadequate perfusion and DO2 in regional vascular beds [2, 3]. Regional hypoperfusion may be absolute as in low cardiac output states, or relative to increased regional O2 demand. While the latter situation is more typical of high output septic shock, the presence of high circulating levels of the potent vasoconstrictor, endothelin-1 in patients with sepsis and multiple organ failure (MOF) suggests that it may be implicated in causing regional vasoconstriction [4].
