BSH Guideline: Evidence-based guidelines developed following a professional literature search and a review of the evidence by the writing group. BSH Good Practice Paper: Used to recommend good practice in areas where there is a less robust evidence base but for which a degree of consensus or uniformity is likely to be beneficial to patient care.
Bleeding events can be controlled by platelet transfusion. Most heterozygotes, with few exceptions, do not have a bleeding diathesis. BSS presents as a bleeding disorder due to the inability of platelets to bind and aggregate at sites of vascular endothelial injury. [4] In the event of an individual with mucosal bleeding tranexamic acid can be ...
Post-transfusion purpura (PTP) is a delayed adverse reaction to a blood transfusion or platelet transfusion that occurs when the body has produced alloantibodies to the allogeneic transfused platelets' antigens. These alloantibodies destroy the patient's platelets leading to thrombocytopenia, a rapid decline in platelet count. [1]
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
Washed red blood cells are red blood cells that have had most of the plasma, platelets and white blood cells removed and replaced with saline or another type of preservation solution. [ 1 ] [ 2 ] The most common reason for using washed red blood cells in transfusion medicine is to prevent the recurrence of severe allergic transfusion reactions ...
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]
The red blood cells are removed by macrophages from the blood circulation into liver and spleen to be destroyed, which leads to extravascular haemolysis. This process usually mediated by anti-Rh and anti-Kidd antibodies. However, this type of transfusion reaction is less severe when compared to acute haemolytic transfusion reaction. [36]
