Non-traumatic rhabdomyolysis:clinical analysis of thirty-nine cases / 中国实用内科杂志

ABSTRACT

Objective To evaluate clinical features,predisposing factors,therapeutic regimen and prognosis of non-traumatic rhabdomyolysis.Methods Clinical picture,therapeutic regimen and prognosis were investigated in 39 cases with non-traumatic rhabdomyolysis by retrospective analysis.Results Non-traumatic rhabdomyolysis mostly presented fever,asthenia,myalgia and/or muscular tenderness,swelling of involved muscles,red urine and oliguria or anuria.The complications and comorbidity of rhabdomyolysis included acute renal failure(ARF),disorders of metabolites and electrolytes,compartmental syndrome,infection,and multiple organ dysfunction.Infection(33.3%)was the most common etiology of non-traumatic rhabdomyolysis,followed by drugs(25.6%),metabolite or electrolyte derangements(10.3%)and alcohol intoxication(7.7%)etc.Therapeutic regimen covered treatment of the underlying diseases,volume repletion,alkalization and dealing with the complications.For the patients with established renal failure,renal replacement therapy was essential.Overall mortality was 15.4%,while the mortality in the patients with ARF was 20.7%.If surviving ARF,the patients' renal function promised to be normalized consequently.Conclusion Non-traumatic rhabdomyolysis is a syndrome with a variety of causes,different clinical presentations and versatile combination of complications,which confounds the diagnosis.However,if treated properly and in time,the survivors in all probability will recover from ARF.
