Two red blood cell units collected in SAG-M additive solution with the ALYX component collection system.
The first protocol available for the new ALYX component system (Baxter Healthcare Inc.) allows automated collection of two Red Blood Cell (RBC) units from one donor. The primary objective of our evaluation was to assess donor safety, comfort and to check the quality of blood products collected. 30 procedures were performed on eligible donors according to French best donation practices. Eligibility criteria were defined in order to ensure a post donation hemoglobin concentration of 11 g/dL minimum. Pre donation ferritin level was also checked. 360 ml of absolute RBC were collected from each donor. Donors physiological parameters and haematological profile were measured immediately before and after donation. Adverse events and donors were observed during the procedure and followed daily during 5 days after donation. Hemolysis in RBC was followed until of shelf life (<0.8% on 42 days storage). The evaluation of different parameters during storage show no difference if we compare with the manual technique. The concentration of hemoglobin is good and all ou concentrates are conform. No serious adverse effects were reported during and after donation. All donors confirmed they would agree to donate 2 RBC units again with this system. We have seen a good quality of RBC products. This evaluation indicates that 2 RBC donation is feasible on the ALYX system, comfortable and safe for eligible donors.
