What is the cause of autonomic dysreflexia?

The most common cause of autonomic dysreflexia (AD) is spinal cord injury. The nervous system of people with AD over-responds to the types of stimulation that do not bother healthy people.

What is the classical signs of autonomic dysreflexia?

In autonomic dysreflexia, patients will experience hypertension, sweating, spasms (sometimes severe spasms) and erythema (more likely in upper extremities) and may suffer from headaches and blurred vision.

What are complications of autonomic dysreflexia?

If left untreated, autonomic dysreflexia can cause seizures, retinal hemorrhage, pulmonary edema, renal insufficiency, myocardial infarction, cerebral hemorrhage, and, ultimately, death. Complications associated with autonomic dysreflexia result directly from sustained, severe peripheral hypertension.

Which are characteristics of autonomic dysreflexia?

However, patients with autonomic dysreflexia may display no symptoms, despite elevated blood pressure.) Profuse sweating above the level of lesion – Especially in the face, neck, and shoulders; rarely occurs below the level of the lesion because of sympathetic activity. Goose bumps below the level of the lesion.

What is autonomic shock?

Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.

What is autonomic dysreflexia pathophysiology?

Autonomic dysreflexia (AD) is a condition wherein the thoracolumbar sympathetic nervous system reacts to a stimulus in an unmitigated and unregulated manner. This may result in symptoms ranging from mild discomfort to extremely severe and occasionally damaging hypertensive crises.

What do you do if a patient has autonomic dysreflexia?

If you feel you have autonomic dysreflexia:

1. Sit up straight, or raise your head so you are looking straight ahead.
2. Loosen or take off any tight clothing or accessories.
3. Empty your bladder by draining your Foley catheter or using your catheter.
4. Use digital stimulation to empty your bowel.

Is autonomic dysreflexia a neurogenic shock?

The joint committee of the American Spinal Injury Association (ASIA) and the International Spinal Cord Society (ISCoS) proposed the definition of a neurogenic shock to be general autonomic nervous system dysfunction that also includes symptoms such as orthostatic hypotension, autonomic dysreflexia, temperature …

What are autonomic functions?

The autonomic system is the part of the peripheral nervous system that is responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.

When is autonomic dysreflexia most likely to occur?

Autonomic dysreflexia (AD) occurs in patients who have experienced a spinal cord injury , and it’s most likely to common in patients who have suffered a T6 or higher injury. This condition happens when an irritating stimulus occurs below the site of spinal injury, which leads to an exaggerated sympathetic nervous system reflex.

What is autonomic hyperreflexia?

Autonomic Hyperreflexia. Basically, Autonomic Hyperreflexia is a situation in which the autonomic nervous system gets hyperactive and this may be caused by some external stimuli.

What is autonomic dysreflexia in neurogenic bladder?

Neurogenic Bladder. Neurogenic bladder is bladder dysfunction (flaccid or spastic) caused by neurologic damage. Symptoms can include overflow incontinence, frequency, urgency, urge incontinence, and retention. Risk of serious complications (eg, recurrent infection, vesicoureteral reflux, autonomic dysreflexia) is high.
