  1. PRISM Pediatric Risk of Mortality, POD Post-operative day, ARF Acute renal failure, MV Mechanical ventilation, PICU Pediatric intensive care unit
  2. aFor patients with cyanotic heart disease, PaO2 was not included in the PRISM score calculation as it is expected that PaO2 would be low for these patients
  3. bTotal fluid intake represents the fluid intake over the first 3 post-operative days
