For patients with acute renal failure, it is normal to keep creatinine within the normal range after dialysis treatment (e.g. creatinine should be kept at 53~106μmol/L for men and 44~97μmol/L for women). In chronic renal failure, the value of creatinine after dialysis has no practical significance, and it is impossible to estimate how much is considered normal.
Hemodialysis is a renal replacement therapy, which can be applied to acute renal failure and chronic renal failure uremic stage, and the normal range of creatinine value is different after dialysis for different conditions.
For acute renal failure, generally caused by acute kidney injury, blood creatinine can be restored to normal level after active treatment and hemodialysis treatment. Therefore, after hemodialysis treatment, blood creatinine is considered normal if it stays at normal level or close to normal level. The normal range of blood creatinine is 53~106μmol/L for men and 44~97μmol/L for women.
For the uremic stage of chronic renal failure, the kidney function has been basically lost and cannot process creatinine by itself. The blood creatinine level reflects the current creatinine content in the body tissues and blood. Hemodialysis can only remove creatinine from the blood, but not from the tissues.
In the uremic stage of chronic renal failure, creatinine will drop for a short time after dialysis, and the specific drop value is related to the creatinine level in the blood, but it will rise again quickly. After dialysis creatinine value can not be reduced to normal range, the specific value has no practical reference significance, and there is no specific range, so it is not possible to estimate how much to maintain is considered normal.
When kidney failure occurs, it is recommended to seek medical treatment in regular hospitals in time, and carry out standardized treatment under the guidance of professional doctors.
