Side-effects of cytapheresis with cell separators.

Area of Science:

• Medical Science
• Hematology

Background:

• Cytapheresis is a critical procedure for blood component collection.
• Assessing procedure-related side effects is vital for patient safety and optimizing cell processing.

Purpose of the Study:

• To evaluate and compare the incidence and types of side effects associated with three different cell processing devices: Haemonetics 30 (H-30), Haemonetics V-50 (H-50), and Fenwal CS-3000.
• To identify differences in side effect profiles between donor demographics and specific cell separator models.

Main Methods:

• A retrospective analysis of 11,895 cytapheresis procedures.
• Procedures were performed using Haemonetics 30 (2,486), Haemonetics V-50 (6,813), or Fenwal CS-3000 (2,596) cell processors.
• Side effect rates were analyzed, with specific attention to hypotension, citrate toxicity, venous access, and technical problems, and stratified by donor sex and device type.

Main Results:

• The overall procedure-related side effect rate was 7.41% (881 events).
• Significant differences were observed between sexes regarding hypotension and citrate toxicity.
• The H-30 processor exhibited the highest rates of hypotension (7.65%) and citrate-related reactions (2.96%).
• Venous access and technical issues were more frequent with the H-50 and CS-3000 processors.

Conclusions:

• While the H-30 processor is associated with higher rates of hypotension and citrate reactions, both the H-50 and CS-3000 cell separators demonstrate a favorable safety profile for cytapheresis.
• The choice of cell separator can influence the type and frequency of side effects, suggesting device-specific protocols may be beneficial.
• Further investigation into donor-specific factors and technical troubleshooting for H-50 and CS-3000 may further enhance procedural safety.
