Preoperative anemia and outcomes after corrective surgery in neonates with dextro-transposition of the great arteries

Abstract Objective The authors aimed to assess whether untreated preoperative anemia was associated with increased risk for adverse outcomes after arterial switch operation in neonates with dextro-transposition of the great arteries (d-TGA). Design Retrospective cohort study. Setting Single cardiac surgery centre. Participants Eighty-two newborns with d-TGA. Exposures The authors divided the cohort into the following two groups: The group of infants with preoperative anemia (defined as a hematocrit Measurements and Main Results Preoperative anemia was diagnosed in 21 (25.6%) infants. Anemic infants received significantly more often intraoperative red blood cell transfusions than controls (81.0% vs. 34.4%, p Conclusions Untreated preoperative anemia was not associated with adverse outcomes in neonates undergoing reparative surgery for d-TGA.
