A pilot study of large volume apheresis of red blood cells and plasma during one donation by allogeneic blood donors.
As a pilot study, we assessed large volume apheresis of red blood cells (RBC) and plasma. The protocol was as follows: (a) 3-RBC group: 3 units (240 ml) of RBC were drawn, (b) RBC+P group: 2 units (160 ml) of RBC and 400 ml of plasma were drawn during one apheresis procedure, and (c)


METHODS
400 ml of whole blood was drawn by a manual method. Each group contained 7 healthy male donors of body weight 54-65 kg. We were able to perform these apheresis procedures without serious complications. Recovery of RBC for the donors of the 3-RBC group was delayed, but the level returned to the pre-donation level within nine weeks. The decreased total protein and albumin in the RBC+P group recovered within one week. The apheresed RBCs demonstrated the same quality as the manually collected RBC. These findings suggest that this apheresis approach may be applicable for routine donation.
