what is the effect of norepinephrine on systemic arterioles
Septic shock is often complicated by systemic hypotension despite normal or increased cardiac output. Restoration of arterial pressure usually requires the administration of systemic vasopressor agents, such as norepinephrine. However, because norepinephrine induces vasoconstriction in other vascular beds, it may decrease visceral blood flow, impairing visceral organ function.
