A 27-year-old man lies supine on the asphalt after a motorcycle crash, his helmet split and gasoline sharp in the hot air. He can speak, but his voice is weak; his hands barely squeeze the examiner’s fingers, while his legs do not move. His skin is warm and dry, his heart rate is 48, and the blood pressure is 82/46. The airway is still open—but the next move has not yet been made.

— What’s your move? Read on.

Before you read
  • What spinal level and respiratory muscles are threatened?
  • Which “traditional” treatment should not be given routinely?

When to Think of It

Trauma with weakness, sensory loss, paresthesias, paralysis, priapism, loss of reflexes, or respiratory failure. Suspect spinal cord injury even with normal-appearing imaging when the examination is abnormal or symptoms are disproportionate.

Sick or Not Sick

Sick vs. not sick: the critical call is whether the patient has threatened ventilation or spinal shock with inadequate perfusion. Persistent hypotension after hemorrhage is addressed—or excluded—before labeling it neurogenic shock.

The First Fifteen Minutes

  • Maintain manual in-line stabilization, oxygenation, cardiac monitoring, two large-bore IVs, glucose, temperature control, and urgent trauma evaluation.
  • GCS ≤8, inability to protect the airway, or progressive weakness → RSI with etomidate 0.3 mg/kg IV and rocuronium 1.2 mg/kg IV, because controlled oxygenation prevents secondary cord injury; avoid neck extension and use video/fiberoptic techniques when feasible.
  • Hypotension after hemorrhage is addressed and no major bleeding source is found → norepinephrine 0.05–0.1 mcg/kg/min IV infusion, titrated to institutional MAP target, because α-mediated vasoconstriction restores spinal cord perfusion with less tachyarrhythmia than dopamine.
  • Bradycardia with hypotension → atropine 1 mg IV, repeat every 3–5 minutes to a maximum of 3 mg, because vagolysis counters unopposed parasympathetic activity; pace if unstable bradycardia persists.
  • Severe pain without shock → fentanyl 25–50 mcg IV, repeated every 5 minutes to effect, because analgesia reduces sympathetic stress without the prolonged hypotension of large opioid boluses.
  • Do not give high-dose methylprednisolone routinely; neurologic benefit is uncertain and infection, GI bleeding, and hyperglycemia increase.

Definitive Care & Disposition

Obtain CT of the spine and MRI for cord compression, ligamentous injury, epidural hematoma, or persistent neurologic deficit. Involve spine surgery and trauma early. Maintain spinal cord perfusion per local protocol—many centers target MAP approximately 85–90 mmHg for 3–7 days, but evidence and targets vary; verify institutional guidance. ICU admission is required for cervical injury, respiratory weakness, vasopressor need, or evolving deficits. Emergent decompression/stabilization is indicated for mechanical instability, progressive deficit, or compressive lesions.

How This One Kills

The fatal error is treating hypotension as “just trauma” while failing to recognize neurogenic shock—or intubating with profound hypoxia and hypotension—allowing ongoing cord ischemia and avoidable neurologic deterioration.
The Differential — What Else Looks Like This
  • Hemorrhagic shock — cool skin, tachycardia, bleeding, narrow pulse pressure; confusing it with neurogenic shock delays hemorrhage control.
  • Spinal shock — flaccid areflexia below the lesion, a neurologic state rather than hypotension; confusing the terms leads to missed shock.
  • Epidural hematoma — rapidly progressive deficit with severe back pain; delayed decompression can cause permanent paralysis.
  • Local anesthetic or sedative toxicity — altered mental status without a trauma-pattern neurologic level; unnecessary spinal procedures delay antidotal/supportive care.

The Second-Day Story

Older adults, intoxicated patients, and those with distracting injuries may report only hand clumsiness, burning paresthesias, or inability to stand. Central cord syndrome can occur after hyperextension without fracture, especially with cervical spondylosis: arm weakness exceeds leg weakness and sacral sensation may persist. Repeat examination after resuscitation and imaging is essential; a normal initial CT does not erase an objective deficit.
Back to Our Patient
Back to the 27-year-old motorcyclist: his paralysis, bradycardia, warm skin, and hypotension after an initial hemorrhage survey support a high cervical spinal cord injury with neurogenic shock. He receives manual stabilization, oxygenation, two IVs, and a focused trauma assessment; because weakness threatens ventilation, he undergoes carefully performed RSI with etomidate and rocuronium. After bleeding is excluded, norepinephrine restores perfusion and atropine treats symptomatic bradycardia. CT demonstrates a cervical fracture-dislocation, and MRI shows cord compression; spine surgery performs urgent reduction and decompression, followed by ICU care and controlled MAP support.
Patient Presentation to Attending
How you’d present this patient on the floor — tight, pertinent positives and negatives, no rambling
“This is a 27-year-old man after a motorcycle crash with acute quadriparesis and hypotension. He is awake but has weak phonation, minimal hand grip, no leg movement, HR 48, BP 82/46, and warm dry skin; I have not found external hemorrhage, and there is no obvious chest or abdominal source yet. His findings are most concerning for a high cervical cord injury with neurogenic shock and impending ventilatory failure. I’m maintaining in-line stabilization, preparing RSI with etomidate and rocuronium, obtaining trauma CT, and starting norepinephrine after hemorrhage assessment, with atropine available for unstable bradycardia. He needs immediate trauma, anesthesia, and spine consultation and ICU disposition.”

Study Directive

  • Draw the differences between spinal shock and neurogenic shock from memory.
  • Practice a 30-second airway plan for a high cervical injury with in-line stabilization.
  • Review your trauma-center MAP target and vasopressor protocol.
  • Complete five cases distinguishing hemorrhagic from neurogenic shock and document the cord level and respiratory implications.
