Extractions: Category : Health Centers Brain and Nervous System Autonomic Hyperreflexia Alternate Names : Autonomic Dysreflexia, Dysreflexia, Hyperreflexia Pictures and Images Attribution Autonomic hyperreflexia is an abnormal triggering of the autonomic nervous system. It occurs after a spinal cord injury . The body is unable to turn off the nerves that cause blood pressure to rise. What is going on in the body? Normally, the autonomic nervous system controls blood pressure automatically. It does this by commanding muscles around blood vessels to tighten or relax in order to raise or lower blood pressure. The nervous system can monitor blood pressure and continually adjusts the commands to keep blood pressure normal. When a person has a spinal cord injury , it can cause damage to nerves in the spinal cord. And this results in a loss of control in the nerves. This can happen if the damage to the spinal cord is in the neck or upper back. The bones of the spine are each labeled and numbered. Damage at the 6th thoracic bone or higher means the person may develop this problem. If the damage is lower, autonomic hyperreflexia will not be a problem.

Extractions: Trevor Dyson-Hudson, M.D. A good example is autonomic dysreflexia. Since needle acupuncture involves the insertion of fine needles into the skin, should people be concerned that it may produce autonomic dysreflexia in individuals with SCI? Very little has been reported on the topic of acupuncture and autonomic dysreflexia in SCI. Rapson and associates (need a pop-up of a PubMed citation here - Rapson LM, Biemann IM, Bharatwai ND, Pepper J, Mustard BE. Acupuncture in the treatment of pain in SCI. J Spinal Cord Med 1995 18:133.) observed no complications while investigating needle acupuncture on SCI subjects. With increased interest in the use of acupuncture on clinical populations, how do we address the risk of autonomic dysreflexia? While autonomic dysreflexia is always a concern, not everyone is at a substantial risk for complications. As a safety precaution, however, clinical trial conduct should be modified to watch for the tell tale signs of trouble. Awareness of the risk of autonomic dysreflexia in SCI subjects, combined with monitoring of associated symptoms such as headache, nasal stuffiness, flushing of the skin, sweating, pallor, or piloerection should be enough to safeguard against the occurrence of this condition in most circumstances.

One of my patients had an episode that was brought on by a dehydrated pea under his lower buttocks. Yes, it is true. His BP shot up, he had a sweaty midsection....it was pretty scary, and it is a life threatning emergency. Also, one can trigger it when changing a foley's. It is important for para's and quads to cath often as the main culprit is usually a distended bladder. I'ts been awhile...so I need to refresh my memory more on this fascinating occurence. robsta 10-19-2004, 03:53 PM
Autonomic Dysreflexia If you exhibit any signs or symptoms of autonomic dysreflexia, it is imperative that The primary cause of autonomic dysreflexia is a distended bladder. http://www.oregonpva.org/AutoDys.html
Extractions: D D Autonomic Dysreflexia, also known as hyper-reflexia, is a life threatening situation. The condition arises when there is a problem that the body is unaware of due to loss of sensation. The brain receives a warning signal but is unable to translate the message into a responsive action because of paralysis. This results in a reaction of the autonomic nervous system causing blood pressure to rise rapidly. If uncorrected, this could lead to a stroke or even death. If you exhibit any signs or symptoms of autonomic dysreflexia, it is imperative that you find the problem and correct it as quickly as possible. The primary cause of autonomic dysreflexia is a distended bladder. Catheterization will relieve the problem. A full bowel is the second most common cause and can be corrected by administering a bowel program. Skin irritations, such as wrinkles in clothing or sitting too close to a fire or heater can also set off dysreflexia. The symptoms of autonomic dysreflexia include: Severe, pounding headache

Extractions: Page: 7 There are a variety of effects that can result from changes in bladder behaviour following SCI. These side effects can include the following: 1. Incomplete bladder emptying and urinary infection Before a SCI people are usually able to completely empty the bladder each time they pass water. This is one of the most important defences against urinary infection. In any situation in which the bladder does not fully empty there is an increased risk of urinary infection from bacteria growing in the urine. Both reflex and flaccid bladders after SCI may not empty fully. Urinary Tract Infection (UTI) may result which as well as causing unpleasant symptoms (such as fever and sickness), can also result in kidney damage. 2. Incontinence of urine Following SCI normal control of urination will be lost. If the bladder develops a reflex pattern it may empty spontaneously without any conscious control. Even with a flaccid bladder incontinence can occur - either because of overflow (continuous dribbling because the bladder is so full) or as a result of a co-existing weakness of the sphincter, this is called stress incontinence. Not only is incontinence unpleasant and sometimes distressing, it can also contribute to skin problems and pressure sore development. By finding information that is relevant to you in this document and perhaps by requesting additional advice, you will be able to address incontinence and prevent it disrupting your life disproportionately.
Extractions: A syndrome associated with damage to the spinal cord above the mid thoracic level (see SPINAL CORD INJURIES) characterized by a marked increase in the sympathetic response to minor stimuli such as bladder or rectal distention. Manifestations include HYPERTENSION; TACHYCARDIA (or reflex bradycardia); FEVER; FLUSHING; and HYPERHIDROSIS. Extreme hypertension may be associated with a CEREBROVASCULAR ACCIDENT.

Rolling Across Alabama- Medical Issues And Treatments autonomic dysreflexia. What is autonomic dysreflexia? autonomic dysreflexia,also known as hyperreflexia, means an overactivity of the Autonomic Nervous http://www.rollingacrossalabama.org/medical/m_issues1.htm
Extractions: Autonomic dysreflexia, also known as hyperreflexia, means an over-activity of the Autonomic Nervous System causing an abrupt onset of excessively high blood pressure. Persons at risk for this problem generally have injury levels above T-5. Autonomic dysreflexia can develop suddenly and is potentially life threatening and is considered a medical emergency. If not treated promptly and correctly, it may lead to seizures, stroke, and even death. AD occurs when an irritating stimulus is introduced to the body below the level of spinal cord injury, such as an overfull bladder. The stimulus sends nerve impulses to the spinal cord, where they travel upward until they are blocked by the lesion at the level of injury. Since the impulses cannot reach the brain, a reflex is activated that increases activity of the sympathetic portion of autonomic nervous system. This results in spasms and a narrowing of the blood vessels, which causes a rise in the blood pressure.
