This article discusses autonomic dysreflexia, which can occur in patients with spinal cord injury. This potentially lifethreatening complication can be managed through an understanding of the disorder and its primary causes. The primary cause of this problem is usually a noxious stimuli that precipitates an abnormal response from the autonomic nervous system. Prevention is the primary nursing treatment and includes implementation of a bladder and bowel management program early in the treatment of the patient with spinal cord injury.
