Which is a key component in crush injury management?

• A. Close monitoring of renal perfusion/health (rhabdomyolysis)
• B. Immediate nephrectomy
• C. Avoid fluids
• D. Prophylactic dialysis

Answer: (A)

Crush injuries carry a high risk of rhabdomyolysis with subsequent acute kidney injury from myoglobin release. The key to management is protecting the kidneys by closely monitoring renal perfusion and function while aggressively replenishing fluids to maintain urine output. Adequate IV fluids help dilute and flush myoglobin from the kidneys, reducing tubular obstruction and nephrotoxicity, and they allow early detection of trouble such as rising creatinine or hyperkalemia. This approach also supports timely identification and treatment of other rhabdomyolysis signs, so you can intervene before full-blown renal failure develops. Immediate nephrectomy isn’t indicated in crush injuries, and avoiding fluids would worsen kidney injury. Dialysis isn’t a first-line preventative step; it’s reserved for patients with established renal failure or life-threatening electrolyte or acid-base disturbances that can’t be managed conservatively.
