Background:It is not easy to suspect whether newly born infants diagnosed as hypoxic ischemic encephalopathy (HIE) will develop impairment of renal function, so there is an urge to scientifically research about correlations of severity of HIE, which is represented by Sarnat scoring and brain computerized axial tomography (CAT) and serum creatinine level in these newly born infants.Aim:To evaluate renal function in the form of serum creatinine levels in full-term neonates with HIE and their correlation with severity degree of HIE, which is represented by Sarnat scoring and CAT.Aim:To evaluate renal function in the form of serum creatinine levels in full-term neonates with HIE and their correlation with severity degree of HIE, which is represented by Sarnat scoring and CAT.Subjects and Methods:This study was a case–control type. It was conducted on 72 full-term neonates who were classified into group 1, which included 36 full-term neonates who were diagnosed as HIE according to the definition of the World Health Organization and group 2, which included 36 full-term neonates who were matched for age and sex and who served as the control group. Serum creatinine levels were measured at days 1 and 7 postnatally. CAT scans were carried out for cases only.Results:Serum creatinine levels were elevated in group 1 when compared to the control group at days 1 and 7 postnatally. They were significantly correlated to the Sarnat scoring system of HIE, meaning that serum creatinine levels gradually increased with the increase in severity of HIE according to Sarnat and Sarnat staging. A statistically significant difference was observed between serum creatinine levels in patients with different findings of brain CAT, meaning that more elevation in serum creatinine levels were reported with more severe cases represented by marked changes in brain CAT.Conclusion:Serum creatinine levels correlate with the severity of HIE of neonates according to Sarnat scoring and brain CAT.
