Fig 1 CONSORT diagram of infants randomly assigned to a conservative or liberal transfusion protocol. (BiV = biventricular; CPB = cardiopulmonary bypass; ECMO = extracorporeal membrane oxygenation; FU = follow-up; Pa = palliative; RBC = red blood cell.)

Fig 2 Hemoglobin (Hb) concentrations for infants randomly assigned to a conservative (Cons) or liberal (Lib) transfusion protocol. (A) Admission and discharge Hb concentrations between the groups. (B) Admission and discharge Hb concentrations between infants with palliation (Pa) and biventricular (BiV) repairs. (C) Lowest Hb concentrations between the groups. (D) Comparison of mean daily Hb concentrations for all patients. *Statistically significant between transfusion groups; #statistically significant for a lower discharge than admission Hb concentrations; †statistically significant for a greater discharge than admission Hb concentration.

Fig 3 Comparison of the number of red cell transfusions for (A) all patients, (B) biventricular (BiV) patients, and (C) palliated (Pa) patients and (D) volume of red blood cells (RBC) transfused.

Fig 4 Comparison of peak daily arterial lactate concentrations for (A) all patients, (B) biventricular (BiV) patients, and (C) palliated (Pa) patients and (D) percentage of lactate time greater than 2.0.

Fig 5 Comparison of the (A) overall estimated arteriovenous difference (est AV diff), (B) daily average est AV diff for all patients, and (C, D) before-and-after red cell transfusions for all patients. An arteriovenous oxygen difference (avO2diff) of 3.5 to 5.0 mL O2/100 mL was considered normal and is demarcated. *Statistically significant between conservative and liberal patients. (BiV = biventricular; Hb = hemoglobin; Pa = palliative; Trans = transfusion.)
