Neurogenic shock 1301630 216404362 2008-06-01T14:17:25Z 59.101.89.179 '''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) [[Category:Neurology]] [[it:Shock neurogeno]]
