[Single needle results with A-201 and AS-104 cell separators]

Area of Science:

• Hematology
• Medical Technology
• Blood Component Collection

Background:

• Plateletpheresis is crucial for transfusion medicine.
• Advancements in apheresis technology aim to improve efficiency and safety.
• Single-needle techniques offer potential benefits over traditional methods.

Purpose of the Study:

• To compare the performance of two new single-needle apheresis systems, A 201 (Baxter) and AS 104 (Fresenius).
• To evaluate key parameters including donation time, anticoagulant citrate dextrose (ACD) consumption, platelet yield, separation efficiency, and erythrocyte/leukocyte contamination.

Main Methods:

• Comparative study of two single-needle apheresis devices: A 201 (Baxter) and AS 104 (Fresenius).
• Assessment of donation time, ACD usage, platelet collection volume, and purity of collected platelets.
• Quantification of erythrocyte and leukocyte contamination in the apheresis product.

Main Results:

• The AS 104 (Fresenius) demonstrated significantly higher total thrombocyte yield compared to the A 201 (Baxter).
• Separation efficiency was notably better with the single-needle AS 104 system.
• Erythrocyte and leukocyte contamination levels were significantly lower when using the AS 104 machine.

Conclusions:

• The single-needle AS 104 apheresis system offers superior performance in platelet yield and purity.
• AS 104 provides enhanced separation efficiency and reduced contamination, making it a potentially advantageous option for platelet collection.
• These findings support the clinical utility of advanced single-needle apheresis technology for optimizing platelet concentrate production.
