Role of pRIFLE Criteria in Early Diagnosis of Severity Staging of Neonatal AKI and its Impact on Management.

ABSTRACT

Mortality is high among sick neonates who have concomitant acute kidney injury (AKI). This observational study was done at Special Care Baby Unit (SCABU) of Dhaka Medical College Hospital (DMCH), Bangladesh from October 2013 to March 2014 to find out the role of pRIFLE criteria in prediction of severity stages of AKI in neonate and early intervention to see the immediate outcome. A total of 44 neonates with AKI were included, all were treated conservatively and with intermittent peritoneal dialysis (IPD) as needed. The neonate of ≤7 days old comprised the main bulk (n=28) and M F = 21 23. The diagnosis was based on eCCL criteria of pRIFLE showed that 40.9% neonates were at risk of AKI, 20.5% have had already injured. Higher proportions of neonates were classified as failure (38.6%). The distribution of biochemical parameters among three stages of AKI showed serum potassium was significantly higher in failure group (p<0.001). The serum creatinine both at baseline and at next evaluations were significantly raised in the failure group (p<0.001). However, failure group had a significantly longer hospital stay compared to risk and injury group (p<0.001). Multiorgan failure was found to be lower in the risk group compared to other two groups (p=0.026). Majority of the failure group needed dialysis as compared to the risk and injury group (p<0.001). The mortality was progressively higher from risk to failure groups (p=0.106). Overall 27% of the neonates diagnosed AKI by pRIFLE were died of the disease. The study concluded that pRIFLE staging in AKI is useful and sensitive in the diagnosis and management of AKI in neonates.
