文摘Introduction Septic shock remains highly lethal,with a 30-day mortality of approximately 35%.[1]Vascular dysfunction is a key mechanism underlying hemodynamic failure in this context.In addition to microcirculatory abnormalities,[2]vascular dysfunction is characterized by a reduction in vascular tone,which is associated with a diminished responsiveness to vasoconstrictive agents.[3]This leads to arterial hypotension.When severe hypotension impairs the perfusion of vital organs and results in multiorgan failure,even in the presence of normal or elevated cardiac output(CO).
