Autonomic dysreflexia is a condition that is most common in people with spinal cord injuries above T6. Some people with multiple sclerosis can also experience this condition. It happens when stimuli below the level of the injury causes the blood vessels to constrict. This then causes the person's blood pressure to rise very quickly. If you take away the stimulus, the autonomic dysreflexia usually stops.
If you are supporting someone with these conditions, you need to know the signs and symptoms of autonomic dysreflexia and what to do. It's also important that you follow the person's toileting management plan. You need to know what is normal for the person you support. This will help you to notice if something changes.
Autonomic dysreflexia is a medical emergency. It can be life threatening and lead to:
Raised blood pressure. Important note: an adult with a spinal cord injury above T6 usually has a low blood pressure, such as 9O/6O or 1OO/7O. So, someone like this can experience autonomic dysreflexia when their blood pressure reaches what is considered normal in most people (12O/8O).
As well as raised blood pressure, the person may experience one or more of these symptoms:
If the person you support has the above signs and symptoms, get medical help straight away.
They don't need to have all of the symptoms above to experience autonomic dysreflexia.
Autonomic dysreflexia can happen if the person:
Autonomic dysreflexia can also happen during a person's routine bowel management. Rectal or digital stimulation during bowel care or if the bowel motion is difficult to pass, can cause autonomic dysreflexia. This may be short-term and stop with no harmful effects when the stimuli has been taken away, e.g. the bowel motion has been passed. If the symptoms don't get better as soon as the stimuli has been taken away, get medical help straight away.
If you can't find and remove the cause, call for medical help. You shouldn't ignore autonomic dysreflexia.
Long-term treatment and management should look at what causes autonomic dysreflexia for that person. This could be different for each person. Always follow a toileting management plan developed by a health care professional. If there isn't a toileting plan in place, talk to your supervisor, the person's care co-ordinator or other health care professional.
