We often hear of people eating crayfish, or students being physically punished after the kidney failure, these are the fault of rhabdomyolysis syndrome, rhabdomyolysis syndrome often occurs in the case of strenuous exercise, trauma, extrusion, etc., the first will be manifested as muscle pain, meat eye hematuria, urine color can be soy sauce color, the reason is because of myocyte damage, the blood inside a large amount of myoglobin, more than the This is due to myocyte damage and the presence of large amounts of myoglobin in the blood, which exceeds the reabsorption capacity of the renal tubules. Laboratory tests can show a significant increase in lactate dehydrogenase, creatine kinase, myoglobin, urine routine: positive protein and occult blood, electromyography can show myogenic damage, rhabdomyolysis syndrome varies in severity, in mild cases, by drinking more water, bed rest, can avoid renal tubular blockage, and avoid the re-emergence of muscle damage, usually about a week can be self-healing, in severe cases, will be In severe cases, myoglobin will block the renal tubules and cause acute tubular necrosis, leading to acute renal failure, manifested as oliguria, anuria, progressive increase in creatinine and urea, hyperkalemia and acidosis, etc. Treatment requires the use of bedside hemofiltration to remove excess myoglobin from the body and wait for the renal tubules to recover themselves, ranging from 1 week to 3 months.
