What is red blood cells washing?

Red blood cells are a special blood product when red blood cells are washed twice with physiological saline. This type of product will help minimize the risk of accidents during blood transfusions, especially on subjects who have had a pre-20s.

1. What is red blood cells?

Red blood cells are a blood product consisting of red blood cells that have been washed with saline. Accordingly, technicians and hematous doctors will take the units of total blood or red blood cells to wash with 1 to 2 liters of physiological saline by manual method or in an automatic blood cell wasted machine. The product after being washed will be more difficult to avoid the rate of red blood cells deficiency than the original from 10 to 20%.

Thus, since there are a large number of components that have been washed away, the risk of unfavorable symptoms, including blood transfusion accidents, will be minimized. The ingredients consist of 99% of plasma proteins and 85% of leukocy than the original. The residual potassium concentration is only 0.2 mEq/L. The metabolism of other esthesties is almost also completely eliminated. Besides, the washing process also eliminates the cytokines that cause a fever reaction.

Due to the process of processing rye red blood cells that occur in the open system, breaking the sealing of the original whole blood units or rye, the risk of infection is absolutely inevitable. Therefore, this blood product has a short shelf life, no more than 24 hours from the time of processing, although it still needs to be preserved at a temperature of 2 – 6 degrees Celsius. In addition, the removal of anti-blood clot preserving solution also limits the viability and function of the cell.

2. What are the uses of red blood cells?

Red blood cells are instability as follows:

  • Pre-edesthings have had blood transfusion reactions that have not been improved by the transmission of poor leukocy cells
  • Presence of IgA deficiency in the presence of anti-IgA antibodies in the blood
  • Had a severe reator reaction during a previous blood transfusion
  • There has been a severe allergic reaction to creascemia but cannot be prevented with antihistamines before blood transfusions
  • Blood transfusions should be given to babies or fetuses in the uterus.

Blood Transfusion

Red blood cells are in dinhed to transmit to some special objects

However, do not arbitrarily use red blood cells for emergency reasons, patients with mere IgA deficiency, fever reactions can be treated controlled with antipyretics and poor blood white blood products …

In summary, the pre-edesthing of a difficult-to-control blood transfusion accident is a factor to prevent in the next blood transfusion. At this time, red blood cells are the blood product of choice, in order to ensure the safety of patients, maintaining life on critically ill people who need a lifelong blood transfusion.
