Rhabdomyolysis and acute renal failure in intensive care unit.

Rhabdomyolysis is common clinical and laboratory syndrome resulting from skeletal muscle injury and acute renal failure is the most important complication. Acute renal failure is common in critically ill medical patients. The aim of our study was to determine the prevalence of rhabdomyolysis induced acute renal failure in these patients and to established the prognosis of critically ill patients with acute renal failure and rhabdomyolysis. In the study were included 1557 patients treated in our medical intensive care unit. Seventy-three patients had criteria for acute renal failure. Twelve of them (16.4%) had rhabdomyolysis, eight were women and four were men (average age was 71 years). Sixty-one patients (83.6%) had acute renal failure without rhabdomyolysis, 33 were women and 28 were men (average age was 69 years). We found no difference in age and sex between patients with acute renal failure with or without rhabdomyolysis. Ten patients (83.3%) with rhabdomyolysis and 39 patients (63.9%) without rhabdomyolysis had multiorgan failure syndrome. In patients with rhabdomyolysis, the number of failing organs were statistically significantly higher (p < 0.027). Nine patients (75%) with rhabdomyolysis and 27 patients (44.3%) without rhabdomyolysis died. Mortality was statistically significantly higher (p < 0.05) in patients with rhabdomyolysis. Rhabdomyolysis with acute renal failure was frequently observed in patients treated in our medical intensive care unit. Multiorgan failure syndrome was common in these patients and mortality was higher compared to patients without rhabdomyolysis.
