Preoperative Anemia
 
Preoperative anemia , even when mild, is an independent risk factor that can increase perioperative morbidiity and mortalitity. Anemia is a leading risk factor for allogeneic blood transfusion.

Anemia is defined by the World health Organization as a hemoglobin level below 120g/L in women and 130g/L in men. Specific thesholds apply to pregnant women and children. A surgical procedure with a moderate or high blood loss will further aggravate the anemia and deplete iron stores.

A standardized approach for the detection, evaluation and management of anemia in the preoperative setting is an important aspect of an effective Patient Blood Management program


Even though Patient Blood management  should be tailored to the patient, algorithma for anemia management prior to suregery are useful.  The algorithm below was developed by the ONTraC Coordinators.
