Alarmed or unalarmed!! Donor red cell lysis during plateletpheresis procedure

Area of Science:

• Hematology
• Transfusion Medicine
• Medical Device Safety

Background:

• Plateletpheresis is a common procedure for collecting platelets from donors.
• Adverse events in plateletpheresis are infrequent, with most related to donor physiology (e.g., citrate toxicity) or minor procedural effects.
• Kit-related complications are rare but can impact procedure safety and efficacy.

Observation:

• A specific kit-related adverse event during plateletpheresis was identified.
• This event involved mechanical damage to donor red blood cells within the apheresis kit.
• The damage resulted in significant red blood cell lysis during the procedure.

Findings:

• The observed adverse event led to the destruction of donor red blood cells.
• This lysis caused a higher-than-usual loss of red cells for the affected donor.
• The incident was attributed to a mechanical issue with the apheresis kit, not donor-specific factors.

Implications:

• This case underscores the importance of monitoring for rare kit-related adverse events in plateletpheresis.
• Ensuring the mechanical integrity of apheresis kits is crucial for preventing donor complications like red cell lysis.
• Further investigation into kit performance may be warranted to enhance donor safety protocols.
