Background
- Do not confuse with Neurogenic Shock
- Temporary loss of spinal cord function below complete or incomplete spinal cord injury
- Flaccid paralysis, anesthesia, absent bowel/bladder control and reflex activity, priapism
- Can make an incomplete lesion appear as complete
- Cord lesions cannot be deemed complete until spinal shock has resolved
- Bulbocavernosus reflex is among the first to return as spinal shock resolves
- Mediated by S2-S4
- Usually lasts day to weeks
- Resolves when soft tissue swelling improves
- Can think of it as a "concussion" of the spinal cord
Differential Diagnosis
Shock
- Cardiogenic
- Acute valvular Regurgitation/VSD
- CHF
- Dysrhythmia
- ACS
- Myocardial Contusion
- Myocarditis
- Drug toxicity (e.g. beta blocker, CCB, or bupropion OD)
- Obstructive
- Distributive
- Hypovolemic
- Severe dehydration
- Hemorrhagic shock (traumatic and non-traumatic)
