'''Neurogenic shock''' is [[Shock (medical)|shock]] caused by the sudden loss of the [[autonomic nervous system]] signals to the [[smooth muscle]] in [[blood vessel|vessel]] walls. This can result from severe [[central nervous system]] ([[brain]] and [[spinal cord]]) damage. With the sudden loss of background [[sympathetic nervous system|sympathetic]] stimulation, the vessels suddenly relax resulting in a sudden decrease in peripheral vascular resistance and [[hypotension|decreased blood pressure]].
Signs and symptoms:
* [[hypotension]]
* [[bradycardia]]
* warm, dry [[Limb (anatomy)|extremities]]
* peripheral [[vasodilation]]
* venous pooling
*Poikilothermia
*[[Priapism]] Due to PNS stimulation
* decreased [[cardiac output]] (with [[neck|cervical]] or [[Vertebral column|high thoracic]] injury)
==Treatment of Neurogenic shock ==
*Large volumes of fluid may be needed to restore normal hemodynamics
*[[Vasopressor]]s ([[Epinephrine]])
*[[Atropine]] (speeds up heart rate and Cardiac Output)
