Abstract
Decreased renal blood flow plays a vital role in the etiology of acute kidney injury (AKI). In this study, we aim to investigate the role of renal regional oxygen saturation (rSO2 ) reductions in predicting AKI in the first 24h of life. One hundred premature babies with a gestational age of ≤32weeks were included. Renal and cerebral rSO2 s were monitored for 24 h by near-infrared spectroscopy. Infants were followed up for the first 7days for the diagnosis of AKI. Infants' median gestational age was 29 (23-32) weeks, and their birthweight was 1,192±355g. It was found that the renal rSO2 values were lower in the first 24h of life in patients who developed AKI, and this decrease was statistically significant in the first 6h of life. The low renal rSO2 values in the early hours of life in premature babies may have a role in predicting AKI.
