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
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. [20]
In transfusion medicine, transfusion-associated circulatory overload (aka TACO) is a transfusion reaction (an adverse effect of blood transfusion) resulting in signs or symptoms of excess fluid in the circulatory system (hypervolemia) within 12 hours after transfusion. [2]
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 ...
The change in the recipient's platelet count after transfusion is termed the "increment" and is calculated by subtracting the pre-transfusion platelet count from the post-transfusion count. Many factors affect the increment including body size, the number of platelets transfused, and clinical features that may cause premature destruction of the ...
Implementation of the INTERCEPT platelet system at LKI is expected to start in March 2013. ... The INTERCEPT system is designed to reduce the risk of transfusion-transmitted diseases by ...
Prostaglandin E1 (PGE1) is a platelet inhibitor that causes an increase in cyclic adenosine monophosphate (cAMP) in platelets by stimulating adenylyl cyclase activity. cAMP is an intracellular signaling molecule, and the increase in cAMP inhibits calcium mobilization and platelet aggregation induced by activation of the ADP receptor P2Y1 ...
