Treatments that are temporary include intrauterine blood transfusion of the anemic donor twin or exchange transfusions, which remove blood from the recipient twin and then transfusion of the donor. [8] Treating TAPS with fetal laser coagulation of vascular anastomoses is the only potentially effective modality. [9]
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]
Thrombotic thrombocytopenic purpura (TTP) is a blood disorder that results in blood clots forming in small blood vessels throughout the body. [2] This results in a low platelet count, low red blood cells due to their breakdown, and often kidney, heart, and brain dysfunction. [1]
Vos originally described Rh-deficiency syndrome in 1961, when a sample of blood failed to respond with several Rh antisera. However, R. Ceppellini used the term "Rhnull" for the first time. So far, at least 43 people from 14 families have been reported in the literature as having the Rhnull phenotype. [4]
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 ...
[5] [10] PI = post-transfusion platelet count - pre-transfusion platelet count However, it is affected by the number of platelets given in the transfusion (platelet dose) and the patient's blood volume. Larger patients and smaller platelet doses decrease the platelet increment.
Transfusion-dependent anemia is a form of anemia characterized by the need for continuous blood transfusion. It is a condition that results from various diseases, and is associated with decreased survival rates. [1] [2] Regular transfusion is required to reduce the symptoms of anemia by increasing functional red blood cells and hemoglobin count.
Transfusional hemosiderosis is the accumulation of iron in the body due to frequent blood transfusions. Iron accumulates in the liver and heart, but also endocrine organs. Frequent blood transfusions may be given to many patients, such as those with thalassemia, sickle cell disease, leukemia, aplastic anemia, or myelodysplastic syndrome, among ...
