Can Patients in Chronic Renal Failure Be TransfusedBecause kidneys play an important role in making red blood cells, when your kidneys are unable to work normally, you are prone to anemia. Can patients in chronic renal failure be transfused?

Renal failure patients should not be transfused

Anemia in patients with renal failure is different from other anemia, mainly due to chronic renal insufficiency for a long time and the decrease of erythropoietin produced by kidney. At the same time, poisons retained in the body not only inhibit the production of red blood cells, but also destroy the erythrocyte membrane and accelerate the death of red blood cells.

In addition, there are toxic substances such as erythropoietin inhibitors in the blood, which make the reduced erythropoietin be inhibited and difficult to play its role.

In addition, patients often have long-term anorexia, diarrhea and so on, which can easily lead to the lack of iron, folic acid, protein and other nutrients in the body, causing serious anemia.

Blood transfusion alone is not helpful for such anemia.

And if the patient is not transfusing fresh blood, but the blood stored in the refrigerator, the decomposition of dead red blood cells inside can aggravate the accumulation of nitrogen metabolites, which adds a burden to the kidneys that are already unable to work.

How to deal with anemia for kidney failure patients?

Although it is not suitable for patients with renal anemia to transfuse blood, it can not be applied mechanically in clinical practice.

Chronic renal failure patients do not need blood transfusion when hemoglobin >= 6g. If hemoglobin < 6g and has caused severe hypoxia in various organs, a small amount of concentrated red blood cells or a small amount of multiple transfusions can be given to patients to improve the condition of cell hypoxia.

If the patient is found to have a significant bleeding tendency, platelet suspension or fresh blood is needed.

In the absence of the above, erythropoietin, iron, folic acid and other drugs can be given in the treatment. At the same time, the appetite of patients can be regulated from the diet to supplement the lack of nutrients.

The advantages and disadvantages of blood transfusion

Chronic renal failure patients are often accompanied by anemia, and the tolerance to anemia is generally stronger than normal people. Although anemia is serious, many patients have no obvious shortness of breath, chest tightness, and pulse is not as fast as other anemia patients.

Blood transfusion can only temporarily improve anemia and alleviate hypoxemia, but in the short term red blood cells can also drop to the original low level.

Too much blood transfusion can cause elevated blood urea nitrogen and potassium, aggravating the condition.

It also increases the chances of importing hepatitis virus.

Therefore, for patients with chronic renal failure complicated with severe infection, acute massive hemorrhage, severe aluminum poisoning and surgery, the necessary blood transfusion is desirable, but fresh blood or a small amount of red blood cells should be transfused.
