Preoperative patient assessment and workup, involving a multidisciplinary team and a comprehensive blood management protocol. Techniques include:

Addressing preoperative anemia using oral or intravenous iron + erythropoiesis-stimulating agents (e.g. Procrit or Aranesp).

Intraoperative blood conservation strategies include topical or intravenous hemostatic agents (such as fibrin glue, vitamin K, desmopressin, aprotinin, tranexamic acid or aminocaproic acid). Anesthetic techniques include lowering blood pressure, maintaining normothermia, correct patient positioning, high oxygen inspiration, and intensive patient monitoring throughout the procedure.

Surgical techniques include meticulous tissue cutting and sealing with laser, argon beam coagulation, or electrocautery instruments; acute normovolemic hemodilution and/or cell salvage.

Postoperative strategies include maintaining intravascular fluid volume, addressing any wound leakage and correcting anemia. In critical cases of anemia, "heroic interventions" such as hyperbaric treatment may sometimes be employed.
