Practice of autologous preoperative plasmapheresis in Germany in 1993.

Autologous preoperative plasmapheresis which is being performed at the University Hospital of Tübingen since 1984 in advance of surgical, orthopaedic or gynecologic operations, constitutes, in combination with intraoperative autotransfusion (IAT), an optimal method to compensate high losses of intravascular volume. Unlike all other procedures which also substitute lost volume (such as infusion of electrolytic solutions or plasma expanders, haemodilution, retransfusion of preoperatively donated autologous blood, transfusion of homologous plasma or foreign blood) this method grants optimal clotting as well as intravascular retention of volume and in addition to this excludes every risk of infection. Although the therapeutic advantages of autologous preoperative plasmapheresis are well known and confirmed by our statistics (about 75% of the patients do not need any foreign blood), the method is rarely practiced in Germany and mainly performed in specialized hospitals (e.g. in the orthopaedic departments of Tübingen, Ulm, Hamburg, Hannover or Essen). This unfortunate situation is obviously due to some of the following, primarily logistic problems. First of all the procedure of autologous preoperative plasmapheresis needs relatively long planning in advance of the operation (between 2 and 4 weeks) and a number of surgeons renounces the method--even if the patient's medical condition is appropriate and no higher costs are to be expected. The above mentioned alternatives of compensating blood losses are preferred, even if they are in no way comparable in their efficiency. Secondly, in Germany autologous preoperative plasmapheresis is mostly performed by an anaesthetist, who is, however, under our laws obliged to reinfuse the plasma himself, which he has taken from a patient.(ABSTRACT TRUNCATED AT 250 WORDS)
