Double plateletpheresis (DPA) and tailored RBC collection with the Excel-Pro: preliminary results

The Dideco Excel-Pro is frequently used for double plateletpheresis (DPA) when the platelet precount exceeds 280 x 10(3)/l. Platelets are collected as "dry platelets" and the resuspension solution is added when the procedure is over. Even when DPA is carried out the product volume prior to resuspension may be as low as 60 ml. As a result, a third product may be collected along with platelets. Our priority is to collect RBCs and, depending on the donor's BW, tailored RBC collections are carried out. This means that from 400 to 480 ml of PRBC (70% hct) are collected from donors whose BW exceeds 75 kg. The results of the last 27 DPA/tailored PRBC collections are: Donors gender and BW (kg), 19M/8F: 88.4 +/- 7.3 Hemoglobin (g/dl): 15.4 +/- 1.3 Platelet precount (x 10(3)/microl): 308 +/- 45 Volume of blood processed (1): 5.5 Procedure time (min): 81 +/- 3 Platelet yield (x 10(11)): 6.8 +/- 0.6 Avg Hemoglobin content of PBRC (g): 102.6 +/- 12.3 WBC contamination of the platelets: 6.8 +/ -10(5).
