1. Washing red blood cells
Washing red blood cells are especially suitable for patients with renal insufficiency, hyperkalemia, autoimmune hemolytic anemia, paroxysmal nocturnal hemoglobinuria, and history of severe transfusion allergies. The product can prevent or reduce the febrile transfusion reaction or allergic reaction caused by white blood cells, platelets and plasma proteins and reduce the spread of hepatitis virus by removing a large part of plasma, white blood cells and platelets.
Method and content
The washed red blood cells contain only a small amount of white blood cells and platelets, and the plasma protein content is extremely small, and the residual plasma protein content in the product is about 1% or less of the original total protein.
Washing red blood cells should be used as soon as possible on the day of preparation.
2. Less white blood cells
Leukocytic blood and leukocytic red blood cell suspension are mainly used in patients with non-hemolytic transfusion reaction with repeated fever, and long-term repeated use of blood transfusion diseases such as leukemia, aplastic anemia, hemodialysis, bone marrow transplantation, organ transplantation and the like.
Method and content
Leukocytic blood is obtained by removing whole blood from leukocyte processing (such as centrifugation, filtration, adsorption, sedimentation, etc.); leukocyte red blood cell suspension is treated by removing whole blood from plasma and white blood cells. The salt solution is resuspended in red blood cells.
1. The volume of white blood cells and white blood cell red blood cell suspension, red blood cell volume, etc. are basically the same as whole blood and red blood cell suspension, and should prevent blood circulation overload when used.
2. The use of a bedside leukocyte filter to filter whole blood or red blood cell suspension can achieve the removal of white blood cells in whole blood or red blood cell suspension. This method is safer, more convenient and more effective.
