Hydration management for rhabdomyolysis primarily aims to prevent which complication?

In the context of rhabdomyolysis, hydration management is crucial primarily to prevent acute kidney failure. Rhabdomyolysis involves the breakdown of muscle tissue, which releases myoglobin into the bloodstream. High levels of myoglobin can lead to kidney injury, as the kidneys work to filter this substance out of the bloodstream. Adequate hydration helps to dilute the myoglobin in circulation, facilitating its clearance from the kidneys and reducing the risk of tubular obstruction and nephrotoxicity.

While electrolyte imbalances can certainly occur due to rhabdomyolysis—especially increases in potassium and phosphorous that can lead to complications—preventing kidney failure is the primary goal of hydration in this condition. Proper fluid administration also aids in maintaining renal perfusion, which is critical to preventing acute kidney injury.

Muscle cramps and infections are not direct complications of rhabdomyolysis that hydration addresses. Muscle cramps may be a symptom experienced by patients but are not the primary focus of hydration management. Infection risk can increase with muscle damage as well, but it is not the primary complication mitigated through hydration protocols. Thus, the management of hydration specifically targets the prevention of kidney failure as the most significant concern in cases of rhabdomyol
