Follow-up

Further Inpatient Care

  • Hemodialysis or continuous veno-veno hemodialysis (CVVHD) may be needed to treat acute renal insufficiency in patients with myoglobinuria. Recovery often occurs in 10-14 days.
  • Electrolyte complications of rhabdomyolysis, including hyperkalemia and hypocalcemia, may need immediate treatment.
  • In the recovery phase, patients may develop hypercalcemia as calcium precipitated in damaged tissue returns to the circulation.
  • Long-term diuresis may cause hypokalemia.

Further Outpatient Care

  • Patients may need extensive rehabilitation for muscle damage.

Deterrence/Prevention

  • Patients with metabolic muscle diseases must avoid trauma, overexertion, dehydration, and heat injuries.

Complications

  • The most serious complication of myoglobinuria is acute renal failure.
  • Other complications can result from renal shutdown or from the intracellular products released into the system by rhabdomyolysis.

Prognosis

  • Patients with uncomplicated cases of myoglobinuria recover without sequelae.

Patient Education

  • Patients who develop exercise-induced rhabdomyolysis need education in maintaining adequate fluid intake, in oral rehydration, and in pacing their exercise in hot weather or extreme conditions.

Miscellaneous

Medicolegal Pitfalls

  • Monitor the patient with a crush injury or extensive muscle damage for rhabdomyolysis and acute renal failure.
  • Administer fluids to a dehydrated patient or any patient with possible muscle injury until the degree of severity is determined.
  • Warn patients against stressful exercise.
