[Hemorrhagic surgery in two Jehova's witness children refusing programmed autotransfusion: a place for erythropoietin].

We report two cases of haemorrhagic surgery in a 6-year-old and 16-year-old girl, respectively, whose parents were Jehovah's witnesses and therefore opposed to preoperative blood donation, but accepting intraoperative blood salvage. Erythropoietin and intravenous iron were administered preoperatively to increase red cell mass. Intraoperative blood salvage, including normovolaemic haemodilution and intraoperative autologous transfusion, avoided homologous blood transfusion.
