AimThe purpose of our study was to evaluate and analyse the prevalence and association of acute kidney injury (AKI) as defined by paediatric Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease (pRIFLE) and Acute Kidney Injury Network (AKIN) classifications in a paediatric intensive care unit (PICU).MethodsA prospective analysis of all patients that were admitted to our PICU between June 2009 and December 2010 was performed. Patients were classified according to AKIN and pRIFLE criteria.ResultsOne hundred and eighty-nine patients (mean age 45.9 ± 54.7 months; 110 male, 79 female) were enrolled. Sixty-three (33.3%) patients developed AKI by AKIN criteria and 68 (35.9%) patients developed AKI by pRIFLE criteria. All patients that had AKI according to AKIN criteria also had this diagnosis with pRIFLE criteria. Five patients had developed AKI only according to pRIFLE classification, four of them owing to reduction in their estimated creatinine clearance and one of them owing to changes over 1-week period. The mean length of PICU stay was longer, need for mechanical ventilation and mortality rates were higher in patients with AKI when compared to patients without AKI.ConclusionAlthough both pRIFLE and AKIN criteria were very helpful in the detection of patients with AKI even in the early stages of it, pRIFLE seems to be more sensitive in paediatric patients.© 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.
