Incidence of Acute Kidney Injury in 1 - 14 years old Critically ill Children in a Tertiary care Center

Abstract

Introduction:Acute Kidney injury (AKI) is associated with poor outcomes in critically ill hospitalized children. There are very few studies on incidence of AKI based on urine output criteria of KDIGO (Kidney Disease: Improving Global Outcome) and time lag between the fall in urine output and rise in serum creatinine. This study was therefore aimed at determining the same.
 Methods: A prospective study was conducted in the Department of Paediatrics of a tertiary care hospital. 171 critically ill children between one to 14 years who were admitted in PICU were enrolled. Hourly urine output and eight hourly serum creatinine levels were measured and incidence of AKI was calculated along with lag time between fall in urine output and rise in serum creatinine. Outcome of children with AKI was also studied. Data analysis was done using SPSS software version 25.0 and Microsoft excel 2007.
 Results: The mean age + SD of children in the study was 5.5 years ± 3.76 with a range of one to 14 years, with 62.6 % of them being boys. The incidence of AKI in the study population was 14.62%. The mean lag time between fall in urine output and rise in serum creatinine was found to be 13.21 hours. AKI had a significant association with mortality, use of nephrotoxic drugs, inotropes and mechanical ventilation.
 Conclusions: A significant number of critically ill children develop AKI and its occurrence portends a poor outcome. Utilization of the KDIGO reduced urine output criteria as a marker of AKI allows for early detection and intervention
