What is Neurogenic Shock?

Neurogenic Shock
Neurogenic Shock. Plain lateral radiographs (A, B) and intraoperative photograph (C). (A) Preoperative plain radiograph shows L5 degenerative spondylolisthesis with 47% vertebral slip. (B) Postoperative plain radiograph shows L5 vertebral slippage of 23%. (C) Intraoperative imaging after enlargement of the dural tear. The location of the new dural tear is different from that of the primary dural tear (arrow).

Neurogenic shock results from loss of vascular tone associated with anesthesia or secondary to a spinal cord injury.

What is the Pathology of Neurogenic Shock?

The pathology of neurogenic shock is:

-Etiology: The cause of neurogenic shock is  autonomic dysregulation following spinal cord injury, usually as a result of to trauma.

-Genes involved: None. 

-Pathogenesis: The sequence of events that lead to neurogenic shock includes the injury to the spinal cord above the level of T6 which results in hemodynamic changes.

How does Neurogenic Shock Present?

Patients with neurogenic shock are typically males or females 15 years of age or older. The symptoms, features, and clinical findings associated with neurogenic shock include low heart beats, hypotension, and temperature dysregulation.

How is Neurogenic Shock Diagnosed?

Neurogenic shock is diagnosed via CT scan, MRI, hemodynamic monitoring, and clinical exam. 

How is Neurogenic Shock Treated?

Neurogenic shock is treated with hemodynamic stabilization, intravenous fluid resuscitation, vasopressors, and inotropes.

What is the Prognosis of Neurogenic Shock?

The prognosis of neurogenic shock is good if properly managed. The overall prognosis depends on the extent of spinal cord injury and response to treatment.
