Abstract

In neonates with hypoxic-ischemic encephalopathy (HIE), we studied the correlation between cord blood base excess (BE) and kidney function. Among 225 infants, 29 % had oliguria. BE levels differed significantly between oliguric and non-oliguric infants (p < 0.01), with a negative correlation to kidney injury (r = -0.544, p < 0.01). BE < -18 had 85 % specificity and 76 % sensitivity in predicting kidney injury (AUC = 0.88). These findings suggest BE as a valuable indicator of impending kidney injury in HIE infants, though underlying mechanisms may vary.

Keywords: Acute kidney injury; Base excess; Hypoxic-ischemic encephalopathy; Kidney failure; Olyguria.
