Platelet transfusion

What's new

Updated 2023 ESAIC, 2023 BSH, 2020 ISTH, and 2018 ASCO guidelines on platelet transfusion.


Key sources

The following summarized guidelines for the evaluation and management of platelet transfusion are prepared by our editorial team based on guidelines from the British Society for Haematology (BSH 2024,2023,2022), the European Association for the Study of the Liver (EASL 2023), the European Society of Anaesthesiology and Intensive Care (ESAIC 2023), the Pan-European Multidisciplinary Task Force for Advanced Bleeding Care in ...

Diagnostic investigations

Evaluation of thrombocytopenia: as per ESAIC 2023 guidelines, do not use the platelet count alone as a bleeding predictor. Take into account the cause of thrombocytopenia, platelet function, and patient- and procedure-related risk of bleeding when deciding on the need for prophylactic platelet transfusion.

Follow-up and surveillance

Post-transfusion monitoring
As per ASCO 2018 guidelines:
Assess post-transfusion platelet counts to confirm that the desired platelet count level has been reached if platelet transfusions are administered before a procedure.
Assess platelet counts 10-60 minutes after the transfusion if platelet transfusion refractoriness is suspected. Diagnose platelet transfusion refractoriness only when at least two transfusions of ABO-compatible units stored for < 72 hours result in poor increments, as patients may exhibit a poor increment to a single transfusion but show excellent platelet increments with subsequent transfusions.
