Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
The 'shock' in spinal shock does not refer to circulatory collapse, and should not be confused with neurogenic shock, which is life-threatening. The term "spinal shock" was introduced more than 150 years ago in an attempt to distinguish arterial hypotension due to a hemorrhagic source from arterial hypotension due to loss of sympathetic tone ...
The treatment for shock from blood loss is different from that for neurogenic shock, and could harm people with the latter type, so it is necessary to determine why someone is in shock. [105] However it is also possible for both causes to exist at the same time. [ 1 ]
Neurogenic shock is caused by the loss of vascular tone normally supported by the sympathetic nervous system due to injury to the central nervous system especially spinal cord injury. [4] [6] Rupture of a hollow organ, with subsequent evacuation of contents in the peritoneal cavity could also determine neurogenic shock, a subtype of ...
Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. [1] [2] Neurogenic means that the problem originates within the nervous system.
Obstructive shock can occur in the setting of tension pneumothorax and cardiac tamponade. These etiologies should be uncovered in the primary survey. [3] In the setting of head or neck trauma, an inadequate sympathetic response, or neurogenic shock, is a type of distributive shock that is caused by a decrease in peripheral vascular resistance. [3]
Neurogenic: Traumatic brain injury; cervical or high thoracic spinal cord injury: C Cardiogenic: Cardiac tamponade; tension pneumothorax; pulmonary embolism [5] Left ventricular myocardial infarction; cardiomyopathy; bradydysrhythmias [5] [6] H Hypovolemic: Hemorrhage; burns (due to third spacing) [6] Dehydration; diarrheal diseases; aortic ...
Common causes of distributive shock include sepsis, anaphylaxis, and head or spinal cord injury (neurogenic shock). [4] Septic shock is typically caused by an infection or inflammation in the body. Signs of septic shock include fever or hypothermia, petechia, and purpura.
