Platelet count increase as well as platelet survival after transfusion is related to the dose of platelets infused and to the patient's body surface area (BSA). Usually these values are less than what would be expected. Corrected platelet count increment (CCI) = platelet increment at one hr x BSA (m 2) / # platelets infused x 10 11
It can occur due to a rapid transfusion of a large volume of blood but can also occur during a single red blood cell transfusion (about 15% of cases). [2] It is often confused with transfusion-related acute lung injury (TRALI), another transfusion reaction.
Preventive transfusion is often done in those with platelet levels of less than 10 x 10 9 /L. [2] In those who are bleeding transfusion is usually carried out at less than 50 x 10 9 /L. [2] Blood group matching (ABO, RhD) is typically recommended before platelets are given. [2] Unmatched platelets, however, are often used due to the ...
Often, it occurs in tandem with an inflammatory disease as the principal stimulants of platelet production (e.g. thrombopoietin) are elevated in these clinical states as part of the acute phase reaction. High platelet counts can occur in patients with polycythemia vera (high red blood cell counts), and is an additional risk factor for ...
Platelet transfusion alone is normally not recommended except in an emergency and is usually unsuccessful in producing a long-term platelet count increase. This is because the underlying autoimmune mechanism that is destroying the patient's platelets will also destroy donor platelets, and so platelet transfusions are not considered a long-term ...
TRALI is defined as an acute lung injury that is temporally related to a blood transfusion; specifically, it occurs within the first six hours following a transfusion. [ 16 ] It is typically associated with plasma components such as platelets and fresh frozen plasma, though cases have been reported with packed red blood cells since there is ...
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.
Platelets immediately form a plug at the site of injury; this is called primary hemostasis. Secondary hemostasis occurs simultaneously: additional coagulation factors beyond factor VII (listed below) respond in a cascade to form fibrin strands, which strengthen the platelet plug. [1] Coagulation is highly conserved throughout biology.
