The hsPDA was defined by two of the following: moderate-large size, left to right shunt, aortic flow reversal, left atrial enlargement. AKI was defined by neonatal modified Kidney Disease Improving Global Outcomes (KDIGO). Rsat and cerebral saturation (Csat), averaged over 1\u2009hour, were evaluated for the 24-hour period around echocardiography.<\/jats:p><jats:p>\n            Results\u2003Among 77 infants, 29 (38%) had AKI by neonatal modified KDIGO criteria. hsPDA was found on echocardiography in 59 (77%). There were no differences in hsPDA in infants with and without AKI (p\u2009=\u20090.1). Rsat was not associated with AKI (p\u2009=\u20090.3).
