title: Autonomic dysreflexia: pharmacological management of hypertensive crises in spinal cord injured patients.
abstract: Interruption of autonomic pathways by spinal cord injury (SCI) causes dysfunctional autonomic dysreflexia (AD), which was first described in 1917, still remains unrecognized by those in the medical profession not involved in SCI care. Autonomic dysreflexia is a syndrome generally manifest by cardiovascular symptoms and characterized by paroxysmal hypertension. These symptoms appear in patients with spinal cord injury above the sympathetic outflow from the spinal cord (T6). Since patients with high level SCI are usually hypotensive, the high blood pressures that develop during AD represent pressure changes of a magnitude that can cause cerebrovascular accidents and death of the subject. We discuss the therapeutic interventions that abate and curtail the symptoms and prevent the catastrophic sequelae of autonomic dysreflexia.
