Acute exertional rhabdomyolysis

Area of Science:

• Sports Medicine
• Exercise Physiology
• Muscle Physiology

Background:

• Acute exertional rhabdomyolysis involves skeletal muscle injury releasing cellular contents into circulation.
• Recent data indicate this condition is more prevalent and severe than previously understood.
• Potential complications include electrolyte imbalances, disseminated intravascular coagulation, renal failure, and compartmental syndrome.

Purpose of the Study:

• To highlight the increasing recognition and severity of acute exertional rhabdomyolysis.
• To emphasize the importance of clinical suspicion and risk factor assessment in diagnosis.
• To outline diagnostic methods and recommend early intervention strategies.

Main Methods:

• Clinical observation and review of recent reports on acute exertional rhabdomyolysis.
• Emphasis on patient presentation: overexertion symptoms like muscle pain and swelling.
• Evaluation of occupational, recreational, environmental, and medical risk factors.
• Diagnostic screening using urine dipstick tests (orthotoluidine) and serum creatine kinase levels.

Main Results:

• Mild to moderate cases can lead to hyperkalemia, hypernatremia, lactic acidosis, and hyperphosphatemia.
• Severe cases may progress to disseminated intravascular coagulation, renal failure, and compartmental syndrome.
• High index of suspicion is warranted for patients with overexertion symptoms.

Conclusions:

• Early identification of acute exertional rhabdomyolysis through symptom assessment and risk factor analysis is critical.
• Urine dipstick and serum creatine kinase tests aid in diagnosis.
• Prompt intervention with aggressive hydration and close monitoring can prevent severe outcomes and mortality.
