A new blood donation strategy: Automated blood collection (ABC)

Abstract

Background

The aim of this study was to find out if Cobe Trima, a blood cell separator that automatically collects RBC, PLT and plasma, is adequate for routine multiple blood donation by apheresis.

Materials and Methods

Eighty donors underwent multiple blood component donations by Cobe Trima. Blood counts were determined on the apheresis products to analyze their quality.

Results

Eighty procedures were performed collecting 193 products. The average platelet yield was 3.5×10¹¹ (± 0.46) in the 54 single product (SP) procedures and 7×10¹¹ (± 0.88) in the 26 double product (DP) procedures. WBC contamination of the PLT products was 1.7 × 10⁵ (1.2–4.2). The mean platelet efficiency was 60 ± 8.35% for SP and 66 ± 9.59% for DP. The hemoglobin (Hb) content per unit was 46.21 g (± 7.84) in 8 DP and 40.82 g (± 6.41) in 34 SP procedures.

Conclusion

The production of standardized blood components with good PLT yield and low WBC contamination plus high efficiency makes Trima one of the best blood cell separators of the new generation.
