A patient presents with hypotension, warm dry skin, and bradycardia after a spinal injury. What is the most likely diagnosis?

• A. Neurogenic shock
• B. Hypovolemic shock
• C. Septic shock
• D. Cardiogenic shock

Answer: (A)

When a spinal cord injury disrupts sympathetic outflow, the body can lose its ability to maintain vascular tone below the level of injury. That causes widespread vasodilation and pooling of blood, leading to low systemic vascular resistance and hypotension. At the same time, the heart doesn’t receive the usual sympathetic signals to speed up, so the vagus predominates and bradycardia can occur. The vessels in the skin dilate, so the skin feels warm and dry rather than cold and clammy. This combination—hypotension with bradycardia and warm, dry skin after a spinal injury—points to neurogenic shock. In other shocks, you'd expect different patterns: hypovolemia usually brings tachycardia with cool, clammy skin from vasoconstriction; septic shock often presents with fever and tachycardia (early warm phase possible but not the bradycardia seen here); cardiogenic shock tends to have cool, clammy skin and signs of poor cardiac pumping.
