Overview of renal anemia?

Renal anemia refers to the terminal medical syndrome of the renal illness。The main reason of renal anemia is the lack of hemopoietin caused by kidney injury。Hemopoietin is the essence to generate red blood cells。Therefore,the lack of hemopoietin contributes to the lack of red blood cells。When the quantity of red blood cells is blow to the normal standard,renal anemia will occur。It is the main reason of renal anemia。Otherwise,because of the kidney injury,the swamp of numerous toxin in the blood will disturb the generation or metabolism of red blood cells,which is another reason of renal anemia。
The syndromes of renal anemia。
Renal anemia is the simultaneous phenomenon of chronic nephrosis, which usually occurs when the nephrotics’ serum creatinine values is greater than 308umol/L。The explicit syndromes of renal anemia are usually the followings,such as ,sallow complexion,pale lips,nails,and eye conjunctiva,hypodynamia,and easy blooding etc。Therefore nephritic should pay attention to those phenomenoa。Renal anemia is caused by kidney disease,so renal anemia will aggravate with the deterioration of kidney function。
The detrimental effects of chronic renal anemia。
Chronic renal anemia not only accelerates the process of renal injury,but also causes a variety of deadly diseases,such as,heart failure,stenocardia,hemorrhage of digestive tract and cerebral hemorrhage etc。In particular ,the aggravated anemia will influence the children kidney patients’ development of body and brain .Therefore patients with kidney disease should take medical treatment immediately when anemia occurs.
Medical treatment of renal anemia 。
The treatment of renal anemia starts with the cure of renal disease and the recuperation of renal injury, which will stimulate the generation of hemopoietin to accelerate the generation of red blood cells and ease anemia phenomenon。Also,the dialysis of toxin in the blood is a must to kidney patients to reduce the damage to red blood cells。

Otherwise,blood transfusion is another important remedy for renal anemia。Due to the high anemia tolerance of uremia patients,however,too much blood transfusion is dangerous。The blood transfusion is available only when the quantity of hemoglobin is below 70g/L and when the following phenomena occur,such as,deadly anemia heart failure,stenocardia,hemorrhage of digestive tract and cerebral hemorrhage etc。The preferable substance for blood transfusion is red blood cells concentrate。The quantity of transfused blood shall not be too much,because too much blood transfusion will inhibite the generation of erythrogenin which will restrain red blood cells’ generation。
