The presence of warm, red skin below a lesion is indicative of which condition?

The presence of warm, red skin below a lesion is indicative of neurogenic shock. This condition occurs as a result of a disruption of the autonomic pathways within the spinal cord, often following a spinal cord injury. It leads to a loss of sympathetic tone and can cause vasodilation below the level of the injury. This vasodilation results in increased blood flow to the affected areas, causing the skin to appear warm and red.

In neurogenic shock, the disruption to the sympathetic nervous system prevents normal vascular constriction, leading to symptoms such as hypotension and bradycardia. The characteristic warm and red skin is a reflection of the increased blood flow and loss of the normal vasoconstrictive response that would occur under other conditions.

Conditions such as spinal shock primarily involve a temporary loss of motor and sensory function below the level of injury without the significant vasodilation observed in neurogenic shock. Autonomic dysreflexia is characterized by an exaggerated sympathetic response to a noxious stimulus occurring in patients with spinal cord injuries (typically above T6), leading to hypertension and associated symptoms, but it does not manifest as warm, red skin. Brown-Sequard syndrome involves hemisection of the spinal cord, leading to varying deficits on either
