Neurogenic shock

Neurogenic shock is a type of shock that results from the sudden loss of signals from the autonomic nervous system that maintain the normal muscle tone in blood vessel walls. This can lead to severe low blood pressure.

Causes

Neurogenic shock can be caused by severe central nervous system damage, such as spinal cord injury or brain injury. Other causes can include spinal anesthesia, neurological diseases, and certain drugs.

Symptoms

Symptoms of neurogenic shock can include hypotension, bradycardia, and hypothermia. Other symptoms can include nausea, vomiting, and fainting.

Diagnosis

Diagnosis of neurogenic shock is typically based on the presence of characteristic symptoms and a history of a recent event that could have caused damage to the central nervous system. Additional tests may be performed to confirm the diagnosis and to rule out other possible causes of the symptoms.

Treatment

Treatment of neurogenic shock typically involves addressing the underlying cause of the shock, such as repairing a spinal cord injury or treating a neurological disease. Medications may be used to help maintain blood pressure and heart rate. In severe cases, hospitalization may be required.
