Higher platelet transfusion thresholds have been used in premature neonates, but this has been based on limited evidence. [19] There is now evidence that using a high platelet count threshold (50 x 10 9 /L) increases the risk of death or bleeding compared to a lower platelet count threshold (25 x 10 9 /L) in premature neonates.

Other anti-platelet drugs are commonly prescribed for patients with acute coronary syndromes such as clopidogrel and ticlopidine. When surgery is undertaken following the administration of these drugs, bleeding can be serious. Transfusion under these circumstances is not clear-cut and one has to use clinical judgment.
Patient Blood Management is an approach that can be implemented in hospital settings for taking care of people who require blood transfusions. [4] PBM includes techniques that may help ensure each person receiving a blood transfusion receives optimal treatment for their condition and also ensures that the blood supply (bank of donated blood) is maintained to ensure that all people who require ...
Post-transfusion purpura is an extremely rare complication that occurs after blood product transfusion and is associated with the presence of antibodies in the patient's blood directed against both the donor's and recipient's platelets HPA (human platelet antigen).
Platelet transfusion is contraindicated in thrombotic thrombocytopenic purpura (TTP), as it fuels the coagulopathy. Platelet transfusion is generally ineffective, and thus contraindicated, for prophylaxis in immune thrombocytopenia (ITP), because the transfused platelets are immediately cleared; however, it is indicated to treat bleeding. [70]
Platelets can be isolated from whole blood using three methods, the platelet rich plasma method, the buffy coat method and with apheresis. Platelets are normally stored at room temperature (20 to 24 °C) in order to preserve their ability to circulate after transfusion. [ 1 ]
Platelet transfusion refractoriness is the repeated failure to achieve the desired level of blood platelets in a patient following a platelet transfusion. The cause of refractoriness may be either immune or non-immune. Among immune-related refractoriness, antibodies against HLA antigens are the primary cause.
Platelet factor 4 can cause heparin-induced thrombocytopenia. The package insert states that prothrombin complex concentrate is contraindicated in patients with disseminated intravascular coagulation, a pathological activation of coagulation, [24] because giving clotting factors would only further fuel this process. However, if the PCC is given ...
