Hemoglobin Value Reduction and Necessity of Transfusion in Bimaxillary Orthognathic Surgery

The individual statistics of the department show that there was only a limited reduction of the intraoperative and postoperative hemoglobin values as a consequence of bimaxillary orthognathic surgery. The increased safety of homologous blood and the minimal transfusion rates support abandonment of routine predepositing of autologous blood and the acceptance of homologous blood in the rare case of transfusion in bimaxillary surgery.
