The ongoing shortage of blood and the risks associated with allogeneic transfusion underscore the need for the prudent use of this precious resource, only when indicated. Accordingly, the World Health Organization (WHO) calls for a rational use of allogeneic blood transfusions in all medical settings, including children, in the perioperative period. 1 The recently published paper in this journal examines the latter in the Nordic countries. 2 Restrictive transfusion practices have long been advocated for the perioperative period in children, with little evidence for the optimal timing and appropriate transfusion triggers. International guidelines, including the updated guidelines from the European Society of Anaesthesiology and Intensive Care (ESAIC) 4 and the Pediatric Critical Care Transfusion and Anemia Expertise Initiative (TAXI), 5 also support such a restrictive transfusion strategy in children who are haemodynamically stable. Individualized clinical assessment in the decision-making process for blood transfusions is recommended, especially in the absence of absolute intraoperative transfusion triggers. This lack of an
