There is little evidence for the use of preventive platelet transfusions in people with chronic bone marrow failure, such as myelodysplasia or aplastic anemia. [16] Multiple guidelines recommend prophylactic platelet transfusions are not used routinely in people with chronic bone marrow failure, and instead an individualised approach should be ...
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 collection.
These can stimulate production of alloantibodies (that is, antibodies against other people's antigens) in recipients of transfused platelets from donors with different HPAs. These antibodies cause neonatal alloimmune thrombocytopenia, post-transfusion purpura, and some cases of platelet transfusion refractoriness to infusion of donor platelets. [1]
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 ...
Treatment of DIC is centered on treating the underlying condition. Transfusions of platelets or fresh frozen plasma can be considered in cases of significant bleeding, or those with a planned invasive procedure. The target goal of such transfusion depends on the clinical situation. Cryoprecipitate can be considered in those with a low ...
If antigen negative platelets are unavailable, then standard neonatal platelet transfusions should be given until antigen negative platelets become available. [20] [19] If a platelet transfusion is not available immediately then the infant can be given IVIG (1g/kg) however, this will have no effect on the platelet count before 24 to 72 hours. [19]
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 ...
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.
