Quick Answer: Key Facts About Neurogenic Shock
Neurogenic shock is a life-threatening condition, almost always caused by a spinal cord injury, in which blood vessels widen and the heart rate slows, so blood pressure drops. [1] [2] Symptoms include low blood pressure, slow pulse and warm, flushed skin. [1] [2] Call emergency services right away. Treatment restores blood pressure with spinal stabilization, IV fluids and medicines, as it can be fatal. [1]

What the research says
The classic picture of neurogenic shock is not always present on arrival. In a database of 490 patients with isolated spinal cord injury in England and Wales, only 19.3% (95% CI 14.8 to 23.7) of those with cervical cord injuries had both a systolic blood pressure under 100 mm Hg and a heart rate under 80 beats per minute when they reached the emergency department. The rates were 7% for thoracic and 3% for lumbar injuries. The authors suggested that the changes may develop over time, so some patients arrive before the shock has become obvious. (Guly et al., Resuscitation, 2008) [3]
Nerve damage explains the combination of low blood pressure and slow heart rate. A review of heart problems after spinal cord injury explained that the injury cuts the brain's control over the sympathetic nerves that start in the T1 to L2 segments of the spinal cord. This leaves the vagus nerve unopposed, which can cause a very slow heart rate (bradycardia) and low blood pressure, mostly in people with cervical or high thoracic injuries. (Grigorean et al., J Med Life, 2009) [4]
Recovery of blood pressure control can take days or weeks. In a case series of 38 patients with acute spinal cord injury and neurogenic shock, adding pseudoephedrine to treatment helped 31 patients (82%) come off intravenous vasopressors or need less atropine. It took an average of 7 days to wean vasopressors, and patients took pseudoephedrine for an average of 32 days. The study was small, retrospective, and had no comparison group. (Wood et al., Pharmacotherapy, 2014) [5]
What Is Neurogenic Shock?
Neurogenic shock is a condition in which the body has trouble keeping its heart rate, blood pressure, and temperature stable because of damage to the nervous system, usually after a spinal cord injury. [1] Unlike shock caused by blood loss or heart failure, it is a failure of communication between the nervous system and the circulatory system. When nerves can no longer tell blood vessels to tighten, the vessels relax and widen, which is called vasodilation. [1] [2] Damage to the nerves can also slow the heart rate. [1] [2]
This widening lets blood pool in the legs instead of returning to the heart and brain. [2] Blood pressure falls, blood flow slows, and vital organs do not get the oxygen and nutrients they need. [1] Without enough blood flow, organs may stop working. [1] This is why neurogenic shock is a life-threatening emergency, and why fast care can protect the brain, heart, and other organs.
What are the signs and symptoms of neurogenic shock?
Spotting neurogenic shock quickly matters because it can become serious fast. Because the condition affects the nervous system, its signs differ from other types of shock. One of the most distinctive is that the skin may feel warm and look flushed at first, because of the widened blood vessels, while other forms of shock usually cause cold, pale skin. [1] [2] The symptoms of the shock phase may last days to weeks, and ongoing symptoms usually come from the original injury. [1]
Primary Symptoms of Neurogenic Shock
What causes neurogenic shock and who is at risk?
Neurogenic shock is almost always caused by a spinal cord injury, most often at or above the T6 level in the neck or upper back. [1] [2] Other conditions and events that disrupt the autonomic nervous system can also trigger it: [1] [2]
How is neurogenic shock diagnosed and treated?
When someone arrives at the emergency room after a suspected spinal cord injury, the medical team focuses first on keeping them safe and stable. Diagnosis combines a physical exam with tests, including blood tests, CT or MRI scans and X-rays to find where the spinal cord is damaged, and an electrocardiogram (EKG) to check the heart. [1]
Immediate Treatment Strategies
The main goals of treatment are to restore normal blood flow and heart rate so that vital organs are protected.
Spinal stabilization: A neck brace or other support keeps the spine steady to prevent more nerve damage. [1] [2]
Fluids: An IV infusion adds fluid to raise blood pressure. [1] [2]
Blood pressure medicines (vasopressors): Drugs such as phenylephrine, norepinephrine, and epinephrine tighten blood vessels and raise blood pressure. [1] [2]
Heart rate support: Drugs such as atropine, glycopyrrolate, isoproterenol, theophylline, and aminophylline help bring a dangerously slow heart rate back to normal. [1] [2]
Care for other injuries: If trauma caused the shock, surgery or other care may also be needed. [1] [2]
What should you do in an emergency if someone has neurogenic shock?
Anyone who may have neurogenic shock after an injury needs emergency help, so call 911 or your local emergency number right away. [1] While you wait for professional help, you can support their circulation:
Keep the person as still as possible to avoid further damage to the spine. [2]
Do not move them, sit them up or turn them unless they are in immediate danger. [1]
Do not lift their legs or change their position; keep the head and neck in line with the body and let trained responders manage blood pressure. [1]
What is the bottom line on neurogenic shock?
Neurogenic shock is a medical emergency in which a spinal cord injury (or, less often, another cause) disrupts the nerve signals that keep blood pressure and heart rate steady. [1] Look for low blood pressure, a slow pulse, and skin that is warm and flushed at first. [1] Call emergency services immediately: fast treatment protects the brain, heart, and other organs, and recovery is possible with the right care and support.
Know the warning signs after a spinal injury. If someone has a spinal cord injury and develops dizziness, confusion, a very slow pulse, or blue or gray lips, call emergency services right away. Every minute counts.
Frequently Asked Questions
How is neurogenic shock different from hypovolemic shock?
Both cause low blood pressure. Hypovolemic shock is caused by losing too much blood or fluid and usually brings a fast heart rate. [1] [2] Neurogenic shock is caused by nerve damage and brings a slow heart rate. [1] [2]
Is neurogenic shock the same as spinal shock?
No. Spinal shock is a temporary loss of reflexes, movement, and muscle tone below the spinal cord injury. [1] [2] Neurogenic shock is a circulatory emergency that affects blood pressure and heart rate. [1]
Can you recover from neurogenic shock?
Yes. With fast treatment to stabilize blood pressure and heart rate, many people get through the shock phase. Outcomes depend on the cause and severity, how quickly treatment starts, other injuries, age, and overall health. [1] Long-term recovery then focuses on the underlying spinal cord injury.
Why does the skin feel warm in neurogenic shock?
Because the nerves can't tell the blood vessels to tighten, the vessels stay widened, and warm blood flows close to the skin's surface. The skin can become cold and clammy later. [1]
At what level of spinal injury does this usually happen?
It most often happens with injuries in the neck or upper back, at or above the T6 level of the spinal cord. [2]
What is autonomic dysreflexia?
It is a strong and sudden rise in blood pressure that can be a complication after spinal cord injury. [1] It is the opposite of the low blood pressure seen in neurogenic shock.
Are there long-term effects?
The shock itself is a short-term emergency, and ongoing symptoms usually come from the original injury. [1] After a spinal cord injury, low blood pressure can last for a long time, and complications such as autonomic dysreflexia, blood clots in the legs, electrolyte changes, and bowel problems can occur. [1] [2]
Can anesthesia or toxins cause this condition?
Rarely. Side effects from spinal anesthesia and toxins that damage the autonomic nervous system are among the other possible causes, although a spinal cord injury is almost always the cause. [1]
What is bradycardia?
Bradycardia is the medical term for a slow heart rate. A slow heart rate together with low blood pressure is a hallmark of neurogenic shock. [2]
How long does the shock phase last?
Symptoms of the shock phase may last from days to weeks, [1] so close monitoring in the hospital is needed.
Can a brain injury cause this?
Yes. Brain injury is listed among the possible causes, though a spinal cord injury is almost always behind neurogenic shock. [1]
Is surgery always required?
No. Surgery may be needed to treat other injuries from the trauma or to relieve pressure on the spinal cord, [1] [2] but the shock itself is treated mainly with IV fluids and medicines. [1] [2]
What are vasopressors?
They are medicines, such as phenylephrine, norepinephrine, and epinephrine, that tighten blood vessels and raise blood pressure during an emergency. [1]
Why is cyanosis a concern?
Cyanosis, a blue, pale, or gray tint to the lips, nails, or gums, is a sign that tissues are not getting enough oxygen. Without fast treatment, this can lead to organ damage.
Can I prevent neurogenic shock?
Because a spinal cord injury is almost always the cause, prevention means avoiding those injuries: wear seat belts in vehicles, follow safety rules in sports, and take care to prevent falls.
