Autonomic dysreflexia


Autonomic dysreflexia is a syndrome characterized by a sudden onset of excessively high blood pressure. If not treated promptly and correctly, it may lead to seizures, stroke, and even death. Autonomic dysreflexia is more common in people with spinal cord injuries that involve the thoracic nerves Click here to see an illustration. of the spine or above (T6 or above).

Symptoms of autonomic dysreflexia include:

  • Flushing or sweating.
  • Headache.
  • A red face or red blotches on the skin.
  • Nausea.
  • Goose bumps.
  • Cold, clammy skin.

If you feel you have autonomic dysreflexia:

  • Sit up straight, or raise your head so you are looking straight ahead. If you can lower your legs, do so. You need to be sitting upright until your blood pressure is back to normal.
  • Loosen or take off any tight clothing or accessories. This includes braces, catheter tape, hose, shoes, and bandages.
  • Empty your bladder by draining your Foley catheter or using your catheter.
  • Use digital stimulation to empty your bowel.
  • Check your skin for red spots that indicate a potential pressure sore.
  • If possible, take your blood pressure every 5 minutes to see if it improves.
  • Call your health professional, even if symptoms go away and your blood pressure is decreasing.
  • If the symptoms return, repeat the above steps and go to the emergency room or call emergency services.

Autonomic dysreflexia occurs when something happens to your body below the level of your injury. This can be a pain or irritant (such as tight clothing or something pinching your skin) or a normal function that your body may not notice (such as having a full bladder and needing to urinate). These situations trigger an automatic reaction that causes your blood pressure to go up. As your blood pressure goes up, your heartbeat slows and may become irregular. Your body cannot restore your blood pressure to normal because of your spinal cord damage. The only way to return things to normal is to change the situation—for example, by removing tight clothing or emptying your bladder.

The following are some frequent causes of autonomic dysreflexia and how you can prevent them.
