WebMay 15, 2024 · In addition, excessive vasoconstriction can result in decreased end-organ perfusion, primarily caused by norepinephrine infusions without appropriately treating hypovolemia; this can be detrimental as most patients who require infusions of norepinephrine already have poor oxygen delivery or utilization. [11] WebNorepinephrine secretion and epinephrine secretion are stimulated by exposure to ice and are secreted into the blood vessels, resulting in vasoconstriction. If the tissue temperature drops below 15 °C, vasodilation occurs as a result of paralysis of the musculature, which provides vasoconstriction or a conduction block of the sympathetic ...
