Association between preoperative anaemia, transfusion, and outcomes in children undergoing noncardiac surgery
Authors' conclusion
The incidence of preoperative anaemia and transfusion in children have remained stable in the last 11 yr. Anaemia, transfusion, and the combination of both increased 30-day mortality and the incidence of postoperative complications.
