Neurogenic Shock

Neurogenic shock is a type of distributive shock that describes the sudden loss of autonomic tone due to spinal cord injury often characterized by hypotension and relative bradycardia. Loss of sympathetic tone occurs with injuries above T6 and results in decreased systemic vascular resistance. Peripheral vasoconstrictors, chronotropes, and inotropes may be needed in cases of neurogenic shock. Autonomic instability may develop and often persists several weeks after the injury. Aggressive management is imperative in the initial phases of neurogenic shock to avoid further secondary ischemic injury to the cord.
