Abstrakt:	Objectives: Acute kidney injury is characterized by sudden and generally revertible renal function impairment involving inability to maintain homeostasis. In pediatrics, the main causes of acute kidney injury are sepsis, use of nephrotoxic drugs and renal ischemia in critically ill patients. The incidence of acute kidney injury in these patients ranges from 20 to 30%, resulting in increased morbid-mortality, a 40 to 90% rate. This study aimed to evaluate the incidence of acute kidney injury in intensive care unit patients, to categorize the severity of the acute kidney injury according to the Pediatric Risk, Injury, Failure, Loss, End-Stage (pRIFLE), examine the relationship between the acute kidney injury and severity using the Pediatric Index of Mortality (PIM) and to analyze outcome predictors. Methods: A prospective study of the patients admitted to the intensive care unit of Hospital Infantil Joana de Gusmão - Florianópolis / SC - Brazil was conducted between July 2008 and January 2009. Were evaluated daily the urine output and serum creatinine, and the patients were categorized according to the pRIFLE criteria. Results: During the follow-up period, 235 children were admitted. The incidence of acute kidney injury was 30.6%, and the maximal pRIFLE score during hospitalization was 12.1% for R, 12.1% for I and 6.4% for F. The mortality rate was 12.3%. The patients who developed acute kidney injury had a ten times bigger risk of death versus the not exposed patients. Conclusions: Acute kidney injury is frequent in critically ill patients. Early diagnosis and prompt and appropriate therapy for each clinical aspect may change this condition's course and severity, and reduce the patients' morbidity and mortality.
