Autonomic dysreflexia

R. K. Khurana

Research output: Chapter in Book/Report/Conference proceedingChapter


Autonomic dysreflexia is a medical emergency. It occurs in individuals with spinal cord injury at or above the T6 level, disconnecting the caudal spinal region and splanchnic sympathetic outflow from supraspinal control. Visceral or somatic stimuli caudal to the lesion produce acute rise in blood pressure, hyperhidrosis, flushing, pounding headache, nasal congestion, and piloerection. Awareness of autonomic dysreflexia, its prompt clinical recognition, and removal of offending stimuli are important. A quick and systematic treatment of elevated blood pressure can avert serious consequences.
