Several studies have now assessed the benefit of using preventive platelet transfusions in adults with dengue who have profound thrombocytopenia (platelet count < 20 x 10 9 /L. [17] There is no evidence that this reduce the risk of bleeding, but there is evidence that they increase the risk of harm due to the platelet transfusion (increased ...
Platelet transfusions are generally not recommended. [6] About 1 per 100,000 people are affected. [3] Onset is typically in adulthood and women are more often affected. [3] About 10% of cases begin in childhood. [3] The condition was first described by Eli Moschcowitz in 1924. [3] The underlying mechanism was determined in the 1980s and 1990s. [3]
Platelets collected by using apheresis at an American Red Cross donation center. Not all platelet transfusions use platelets collected by automated apheresis. The platelets can also be separated from donations of whole blood collected in a traditional blood donation, but there are several advantages to separating the platelets at the time of ...
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 ...
Originally, platelets were stored in the donor’s own plasma. Nowadays, many blood banks have switched to using platelet additive solution to store platelets. Typically, when platelets are isolated from whole blood, not all plasma is removed, as platelets need to be in a certain volume of plasma in order to have a clear separation from other ...
For apheresis platelet donation the donor's pre platelet count should be above 150 x 10^9/L. For apheresis plasma donation, the donor's total protein level should be greater than 60 g/L. For double red cell apheresis, donors of either gender require a minimum hemoglobin level of 14.0 g/dl. [16]

Platelet transfusion is discouraged, as this too may aggravate thrombosis. [34] UK guidelines by the British Society for Haematology recommend the administration of intravenous immunoglobulin (IVIG) to reduce levels of the pathogenic antibody. [34] Low fibrinogen levels may require correction with fibrinogen concentrate or cryoprecipitate. [34]
