| pubmed-article:3087724 | pubmed:abstractText | Acute renal failure (ARF) is common among critically ill patients and renal dysfunction is often associated with the multisystem organ failure syndrome. The mortality of ARF remains high but animal data indicate that prevention and early treatment may decrease the morbidity and mortality. This review defines ARF based on urine volume, laboratory parameters, and clinical presentation. The pathophysiology of prerenal, postrenal, and intrinsic ART are differentiated and diagnostic criteria provided. Preventive therapy, supportive care, and proposed treatments are outlined. Studies examining the prevention and treatment of ARF in animal models and trials in humans are evaluated. Mannitol 0.5-1 g/kg, furosemide 0.5-1 mg/kg initially, and dopamine 1-5 micrograms/kg/min are effective in preventing or decreasing the severity of ARF in animal models. In humans these drugs are effective at maintaining urine output in various clinical situations and converting oliguria to nonoliguria in some patients; however, increased survival has not been adequately proven as of yet. Dialysis and experimental therapy are briefly discussed. | lld:pubmed |
