Autologous transfusion is widely used in many surgical procedues because of its safety. It allows avoidance of infectious disease mediated by blood. At Okayama University Dental Hospital, cases of autologous transfusion has increased in the last several years. However, autologous transfsusion depends on the subjective judgement of the physician in charge of the patient. Therefore, we assessed the autologous transfusion in scheduled surgery performed in the last five years at our hospital. We investigated 198 cases. Most of the cases were repositioning of the mandible, the maxilla or both. The number of instances of each procedure were 93, 10 and 91, respectively. The mean values of blood loss were 169.9 ml, 232.5 ml and 330.2 ml, respectively (Fig. 1). The rates of cases in which blood loss was more than 600 ml were 4.3%, 0% and 11%, respectively (Fig. 2). The averages of amounts of autologous blood prepared were 409.6 ml, 382.2 ml and 448.3 ml, respectively (Fig. 3). For repositioning of both mandible and maxilla, a preserved autologous transfusion was prepared in 80.2% of the cases. For repositioning of the mandible, a dilutional autologous transfusion was prepared in 67.7% of the cases (Fig. 4). The preserved autologous transfusion was carried out in 9.5% of the cases involving repositioning of both mandible and maxilla, and in none of other repositioning surgeries (Fig. 5). Mean values of hemoglobin before surgeries in patients whose preserved autologous blood had been taken a couple of weeks prior to surgery were within normal range (Fig. 6). Since no homologous transfusion was necessary in any of the cases, we believe that one of the goals of autologous transfusion was achieved. However, preparing autologous transfusion may be done excessively for these procedures. Furthermore, since a small amount of dilutional autologous transfusion in our facility may not be effective, the preparation of autologous blood for the repositioning of the mandible should be re-assessed carefully.
