Crush Syndrome

What Is Crush Syndrome?

Crush Syndrome describes the same pathophysiology as crush injury syndrome, myoglobin, potassium, and other cellular contents flooding circulation after prolonged compression is released, but this entry focuses on the mass-casualty and pharmacological management side rather than single-patient extrication timing. In a multi-victim structural collapse or earthquake response, triage systems (START, SALT) have to account for the fact that a patient who looks stable while pinned can deteriorate rapidly the moment they're freed, which affects both triage category assignment and the sequencing of which victim gets extricated first when resources are limited. Field pharmacological management beyond IV fluids includes sodium bicarbonate (to counter metabolic acidosis and help stabilize cardiac membrane against hyperkalemia), calcium gluconate or calcium chloride (specifically to protect cardiac tissue from hyperkalemia's arrhythmic effects, not to lower potassium itself), and in some protocols nebulized albuterol, which shifts potassium intracellularly as a temporizing measure.

Why Crush Syndrome Matters on the Fireground

In a mass-casualty collapse scenario, triage decisions about which trapped victim to free first aren't just about accessibility, a longer-pinned victim carries higher crush syndrome risk and may need treatment staged before extrication regardless of how stable they currently look. Recognizing that calcium gluconate protects the heart from potassium's effects without actually lowering potassium levels prevents a provider from mistaking it for definitive treatment and skipping the fluid resuscitation and transport priority that patient still needs.

Field Procedures & Tactical Steps

1. Factor entrapment duration into triage prioritization during multi-victim structural collapse response, not just visible injury severity.
2. Coordinate with medical direction on pharmacological management (sodium bicarbonate, calcium gluconate/chloride, nebulized albuterol per protocol) alongside fluid resuscitation.
3. Continue cardiac monitoring and fluid administration after pharmacological intervention, since calcium and bicarbonate address symptoms rather than the underlying potassium load.
4. Prioritize rapid transport to a facility capable of managing acute kidney injury and hyperkalemia once the patient is extricated and stabilized.

Common Context & Application

Factored into triage prioritization during structural collapse or earthquake response with multiple entrapped victims, and referenced when medical direction orders pharmacological management alongside fluid resuscitation for a confirmed crush injury patient.
