Diagnosis: Crush Diagnosis: Crush SyndromeSyndromeDefinition:

◦ A severe, often fatal condition that follows a severe crushing injury, particularly involving large muscle masses, characterized by fluid and blood loss, shock, hematuria, and renal failure. Also known as compression syndrome. (McGraw Hill Dictionary)

◦ In a nutshell: TRAUMATIC RHABDOMYOLYSIS due to crushing

◦Also known as Bywaters Syndrome/ Reperfusion injury

PATHOPHYSIOLOGYPATHOPHYSIOLOGY

Clinical Features

KIDNEY IS IN DANGER AS SOON AS WE RELIEVE THE COMPRESSION

Renal hypoperfusion + Renal Tubular Necrosis = Renal Failure

MANAGEMENTMANAGEMENTInitial Management:

1. Follow the usual criteria of A-B-C as injuries are massive and high chances of poly-trauma

2. Early and rapid rehydration3. Venous access preferably before the limb is

decompressed4. CVP and urinary catheterization for monitoring

Further Management1. Large amount of saline infusion with forced

diuresis2. Debridement of crushed tissue and a

fasciotomy for compartment syndrome3. Dialysis if renal failure sets in4. Amputation as the last resort if massive

limb injury is there and we have to prevent crush syndrome
