Platelet Transfusions in the Critically Ill
- Recommendations for the transfusion of platelets in the critically ill patient is primarily extrapolated from the oncology literature; literature that is predominantly observational and expert opinion.
- Nevertheless, indications for the transfusion of platelets in a critically ill ED patient include:
- active bleeding with a plt count < 50 x 109/L
- plt count < 10 x 109/L (high risk of spontaneous bleeding)
- prior to an invasive procedure when the plt count is < 50 x 109/L
- Importantly, the decision to transfuse platelets should also take into account the clinical setting (ie. a uremic patient with active bleeding)
