  • Title: [Preoperative autologous blood donation and intraoperative autotransfusion in first implantation of hip endoprostheses--a retrospective study].

    Abstract:
    The records of a total of 102 patients who underwent primary total hip replacement during 1987-88 were evaluated retrospectively. 36 patients had donated 1-3 units of whole blood preoperatively. Surgery was performed with the use of a device for intraoperative autotransfusion (IAT). Another 25 patients without preoperative autologous blood donation were operated with the use of IAT. None of these techniques was available for the remaining 41 patients. The mean perioperative blood loss and the mean volume of transfused blood were 1400 ml and 1000 ml respectively. Equal quantities of blood were lost intra- and postoperatively, whereas only one fifth of transfused blood was given intraoperatively. Homologous blood transfusion was not required in 32% of the patients for whom autologous blood was not available. However after preoperative autologous blood donation, 95% of the 2-unit donors and 100% of the 3-unit donors could be operated without homologous blood transfusion. Autologous blood donation did not increase the need for homologous blood transfusions. With the use of IAT it was only 20% of the patients that at least 500 ml of blood were salvaged for retransfusion. On the basis of these findings, elective primary total hip replacement would seem to be the ideal operation to be performed after preoperative autologous blood donation and, whenever possible with the use of IAT. The desirable ratio of 1,5:1 for the units of blood to be crossmatched preoperatively vs. units transfused perioperatively can be achieved solely by preoperative donation of 3 units of autologous blood.
