Abstract
We evaluated the pulmonary complications following orthotopic liver transplantation in children (age <18 y). Twenty-two patients (49%) developed respiratory complications. Pediatric end-stage liver disease(PELD) score >25 and positive fluid balance were independent risk factors. Patients with respiratory complication had significantly higher mortality and intensive care unit stay.
