Population
Children undergoing non-cardiac surgery who had blood loss of more than 20% total blood volume (n= 99).
Intervention
Individualized red blood cell (RBC) transfusion strategy using Pediatric Perioperative-Transfusion-Trigger Score (individualized-strategy group, n= 49).
Comparison
RBC transfusion initiated when the patient’s haemoglobin concentration was lower than 8g per deciliter, or lower than 10g per deciliter for newborns (control group, n= 50).
Outcome
Twenty-six children (53.1%) in the individualized-strategy group received transfusion perioperatively, as compared with 37 children (74%) in the control group. During surgery, children in the individualized-strategy group were exposed to fewer transfusions than in the control group (0.87±1.03 vs. 1.33±1.20 red blood cell units per patient). The incidence of severe complications in the individualized-strategy group had a lower trend compared to the control group (8.2% vs. 18%). No significant difference was found in the other outcomes.
