CONSUMPTION OF HOMOLOGOUS PACKED RED-CELLS - ANALYSIS OF THE FACTORS INVOLVED IN ITS REDUCTION

The factors involved in reducing consumption of bank packed red cells (PRC) were studied over three one year periods (1983, 1987 and 1989) in a Department of Vascular and General Surgery. The effects of autologous blood salvage (started in 1987), associated with the management of homologous blood by a branch of the blood bank inside the operating theater suite were assessed. In 1989, intentional normovolaemic haemodilution became virtually systematic, on top of the intraoperative blood salvage, for all patients due to undergo surgery with a risk of severe blood loss. The number of surgical procedures carried out during those three years did not vary. However, in the same time, the annual consumption of homologous PRC decreased by an overall 56 % (36.7 % between 1983 and 1987, and 29.8 % between 1987 and 1989). This decrease was mostly due to a fall in prescription in the operating theaters, and not in the wards. In the same time, albumin consumption increased sixfold. Such transfusional policies can only be carried out if there is good cooperation between the blood bank and the prescribers of blood products.
