Perioperative anemia

Perioperative anemia is common and is associated with increased need for blood transfusion in the perioperative period. Perioperative anemia has also been linked to increased morbidity and mortality in surgical patients. Anemia may impede a patient's ability to recover fully and participate in postoperative rehabilitation. Preoperative treatment of anemia is associated with a reduction in the need for blood transfusion in the perioperative period. Additional advances in surgical technology that reduce blood loss intraoperatively are associated with a reduction in postoperative anemia and should be used whenever possible. All strategies to prevent anemia in the perioperative period should be considered in an effort to minimize exposure of surgical patients to blood transfusion.
