Septic shock has an estimated hospital mortality of 26%.2 Cardiogenic shock has an estimated hospital mortality of 39% to 48%.3,4 Neurogenic shock occurs in <20% of spinal cord injuries (cervical, 19.3%; thoracic, 7%; lumbar, 3%).5 The definition of and treatment approach to shock continue to evolve, but the initial approach to a patient in shock follows similar principles, regardless of the inciting factors or cause.
