Acute kidney injury after cardiac surgery according to RIFLE: adults vs pediatrics

CONCLUSIONS Aim was to evaluate incidence, risk factors, outcome of acute kidney injury (AKI) in adult and pediatric patients after cardiac surgery in intensive care unit (ICU), based on RIFLE and RIFLE modified criteria; AKI association with clinical outcomes, and predictive factors for ICU mortality. All patients admitted in the cardio surgical ICU, tertiary care center, during 2007 were reviewed retrospectively. Transplanted and chronic dialysis patients before admission to the ICU were excluded. AKI was classified according to the maximum RIFLE criteria using both estimated creatinine clearance (eCCl) and urine output (UO) criterion during the first week of stay. For pediatric patients (≤18 years) RIFLE modified was used. For baseline creatinine, was used that of hospital admission.
