Which type of shock results from damage to the spinal cord?

• A. Obstructive Shock
• B. Cardiogenic Shock
• C. Neurogenic Shock
• D. Anaphylactic Shock

Answer: (C)

Neurogenic shock occurs as a result of damage to the spinal cord, often due to trauma or severe injury. This type of shock is characterized by the loss of sympathetic tone caused by the disruption of nerve pathways in the spinal cord, leading to vasodilation. When the sympathetic nervous system cannot maintain normal vascular constriction, it results in decreased blood pressure and inadequate blood flow to vital organs. The accumulation of vasodilation causes blood to pool in the periphery, which can result in hypoperfusion even though the overall blood volume may be normal.

Unlike other types of shock, neurogenic shock significantly alters the normal regulation of heart rate and vascular tone. This condition is particularly notable in cases of spinal cord injury at or above the T6 vertebra, where autonomic dysfunction is common. Recognizing neurogenic shock is vital for timely and appropriate medical intervention, which may include stabilizing the spine and supporting blood pressure.
