What vital sign changes are indicative of neurogenic shock?

In neurogenic shock, one of the hallmark features is the presentation of warm, dry skin, which is a result of the loss of sympathetic tone due to interruption of the autonomic nervous system, typically seen in spinal cord injuries. This disruption prevents proper vasoconstriction, leading to peripheral vasodilation. As a consequence, blood flow is redirected to the periphery, resulting in the skin feeling warm and appearing flushed, while simultaneously, the patient can be hypotensive.

The absence of sweating in the affected areas contributes to the skin feeling dry. This contrast in skin temperature and moisture levels is significant in differentiating neurogenic shock from other forms of shock, such as hypovolemic or septic shock, which often feature cool, clammy skin due to peripheral vasoconstriction.

In this context, understanding the implications of skin characteristics in neurogenic shock can be critical for rapid assessment and management of patients in trauma settings.
