Crush syndrome is managed by
**Core Concept**
Crush syndrome is a severe and potentially life-threatening condition that occurs when there is a crush injury to a limb, leading to tissue death and subsequent release of large amounts of myoglobin into the bloodstream. This can cause acute kidney injury (AKI) due to the precipitation of myoglobin in the renal tubules.
**Why the Correct Answer is Right**
The management of crush syndrome involves the administration of fluid resuscitation to maintain renal perfusion and prevent the precipitation of myoglobin in the renal tubules. Mannitol is often used as a diuretic to help increase urine output and promote the excretion of myoglobin. Additionally, alkalization of the urine with bicarbonate may be necessary to prevent the precipitation of myoglobin. The use of mannitol and bicarbonate helps to maintain renal function and prevent the progression of AKI.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not address the underlying pathophysiology of crush syndrome, which is the release of myoglobin into the bloodstream.
**Option B:** This option is incorrect because it does not mention the use of diuretics, which are essential in the management of crush syndrome to promote the excretion of myoglobin.
**Option C:** This option is incorrect because it does not provide a comprehensive approach to the management of crush syndrome, which involves fluid resuscitation, diuretics, and alkalization of the urine.
**Clinical Pearl / High-Yield Fact**
One of the key points to remember in the management of crush syndrome is the importance of early fluid resuscitation to prevent the precipitation of myoglobin in the renal tubules. This can be remembered using the mnemonic "MUDPILES," which stands for Muscle, Urine output, Diet, Potassium, Insulin, Lactate, Electrolytes, and SODIUM.
**Correct Answer: B. Fluid resuscitation with mannitol and bicarbonate to maintain renal perfusion and promote the excretion of myoglobin.**
