Acute normovolemic hemodilution

In the acute normovolemic hemodilution (ger .: acute normovolaemic haemodilution ) is a method that originally only for use in Jehovah's Witness was thought that transfusion with allogeneic blood refuse to do not have to fall back when the scheduled major operations in foreign blood.

Immediately before the operation, the patient's (own) whole blood is taken in order to replace it with a colloidal infusion solution and thus lower the hematocrit to a tolerable target value. During the operation, this is then kept stable by reinfusion of the previously obtained autologous blood.
