Outcome of acute kidney injury in pediatric patients admitted to the intensive care unit

Background: Acute kidney injury (AKI) is common in the pediat- ric intensive care unit (PICU). We aimed to describe the etiology, clinical features, and outcome of AKI in pediatric patients and to determine the predictors for ini- tiation of renal replacement and mortal- ity. Methods: A retrospective chart review was performed of the medical records for all patients who were admitted to the PICU at King Abdulaziz University Hospital be- tween January 1 and December 31, 2011. The pediatric-modified RIFLE criteria were used to classify AKI. Results: We included 102 children with AKI, aged 4 - 60 months. Oliguria (61.5%, p < 0.0001) and hyper- volemic signs (38.5%, p = 0.03) were more common among patients with RIFLE class failure. They also had the highest mortality (53.9%, p = 0.01). Oliguric patients were
