Comparison of Plateletpheresis on the Haemonetics and Trima Accel Cell Separators

The use of apheresis equipment to collect platelets has rapidly increased in recent years. We compared two apheresis instruments (Haemonetics MCS + and Trima Accel) with regard to platelet (PLT) yield and efficiency, and collection rate (CR) in a retrospective study. Overall 120 data obtained by Haemonetics and Trima systems (N = 60 for each) were randomly selected among 400 plateletpheresis procedures performed at the Apheresis Unit of Kayseri Education and Research Hospital between July 2016 and January 2017. The CR was significantly higher with the Haemonetics compared to the Trima (0.076 ± 0.016 vs. 0.065 ± 0.015 (PLT × 10¹¹ /min) respectively; P < 0.001). The PLT yield/unit was higher with the Haemonetics (4.4 ± 0.8 vs. 3.9 ± 0.8 × 10¹¹ , P = 0.001). Haemonetics and Trima Accel instruments collected platelets efficiently. We hope that these data will be a guide in selecting equipment for apheresis units.
