Which condition involves muscle breakdown releasing toxins into the bloodstream?

• A. Crush Injury
• B. Rhabdomyolysis
• C. Tourniquet
• D. Crush Syndrome

Answer: (D)

When muscle tissue is severely damaged and compressed for a period, its contents spill into the bloodstream. This systemic response after crush injuries is called crush syndrome, and it stems from massive muscle breakdown (rhabdomyolysis) with the release of toxins like myoglobin and electrolytes into circulation. The myoglobin can clog renal tubules and trigger acute kidney injury, while released potassium can cause dangerous heart rhythms. So while rhabdomyolysis is the process of muscle breakdown, crush syndrome is the broader condition that describes the resulting toxins entering the bloodstream and the ensuing systemic effects after a crush injury. In practice, management centers on rapid removal from the crush, maintaining airway and breathing, and aggressive IV fluids to protect the kidneys and dilute the circulating toxins, along with monitoring electrolytes and renal function.
