Neurogenic shock
Neurogenic Shock
Neurogenic shock (/nʊərəˈdʒɛnɪk ʃɒk/) is a type of shock that results from the sudden loss of the sympathetic nervous system signals to the smooth muscle in vessel walls.
Etymology
The term "neurogenic" is derived from "neuro" meaning nerve and "genic" meaning origin. "Shock" in this context refers to a sudden drop in blood flow through the body.
Definition
Neurogenic shock is a life-threatening condition often caused by severe injury or trauma to the spinal cord. This can result in a significant decrease in heart rate and blood pressure, leading to inadequate blood flow to the body.
Symptoms
Symptoms of neurogenic shock can include:
- Hypotension (low blood pressure)
- Bradycardia (slow heart rate)
- Difficulty breathing
- Fainting
- Weakness or paralysis
- Cold, clammy skin
Causes
Neurogenic shock is most commonly caused by a severe spinal cord injury. Other potential causes can include brain injury, spinal anesthesia, and certain medications.
Treatment
Treatment for neurogenic shock typically involves addressing the underlying cause, such as surgery to repair a spinal cord injury. Medications may also be used to increase blood pressure and improve blood flow.
