Ann Surg 2022; 275: 456-466.
Fourteen trials including 8641 procedures were studied. A restrictive blood transfusion policy did reduce the volume of blood transfused without increasing postoperative morbidity. Two of the trials did show adverse composite outcomes for restrictive transfusion.
Comment: The result isn’t definitive, but further evidence that restrictive transfusion is generally not harmful.
