Large volume apheresis of autologous plasma and preparation of autologous fibrin glue from the plasma.
Autologous blood transfusion (ABT) is useful for prevention of undesirable effects of allogeneic blood transfusion. In our hospital, not only autologous whole blood but also autologous red blood cells, autologous fresh frozen plasma (Auto-FFP), and autologous fibrin glue (Auto-FG) are routinely produced for surgical patients. The Auto-FG is prepared from plasma which is separated from manually collected whole blood. However, when a large volume of Auto-FG is required, the plasma obtained by an apheresis method may be useful. Therefore, a pilot study was conducted to determine whether a collection of 2 U (160 ml) of red blood cells (RBCs) and 400 ml of plasma at 1 apheresis is acceptable. We first performed the apheresis on healthy donors, and then applied for autologous blood donation. The apheresis is safe. The collected plasma is used for the production of Auto-FFP and Auto-FG. The remaining RBCs also are used for ABT. The preparation of Auto-FG is simple, and it is effective for the reduction of allogeneic fibrin glue.
