ysis of the Neonatal and Pediatric Heart and Renal Outcomes Network (NEPHRON) multicenter cohort who underwent S1P. Using neonatal modification of Kidney Disease Improving Global Outcomes (KDIGO) criteria, perioperative associations between CS-AKI with morbidity and mortality were examined. Sensitivity analysis, with the exclusion of prophylactic peritoneal dialysis (PD) patients, was performed. SETTING: Twenty-two hospitals participating in the Pediatric Cardiac Critical Care Consortium (PC4) and contributing to NEPHRON. PATIENTS: Three hundred forty-seven neonates (< 30 d old) with S1P managed between September 2015 and January 2018. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 347 patients, CS-AKI occurred in 231 (67%). The maximum stages were as follows: stage 1, in 141 of 347 (41%); stage 2, in 51 of 347 (15%); and stage 3, in 39 of 347 (11%). Severe CS-AKI (stages 2 and 3) peaked on the first postoperative day.
