What should be the creatinine level after dialysis

Dialysis refers to hemodialysis, and hemodialysis mainly removes impurities from a person's blood and artificially injects some substances essential to the body. Hemodialysis is mainly for patients with uremia because the creatinine in their blood is abnormally high. At this time, dialysis is needed to reduce the creatinine in the blood, but what should the patient's blood creatinine level be after dialysis?

Still high. It is usually around 200. Dialysis is a separation and purification technology that separates small molecules from biomacromolecules by the principle of small molecules diffusing into water (or buffer) through a semipermeable membrane. Dialysis therapy is a treatment method that allows components (solutes or water) in body fluids to be excreted from the body through a semipermeable membrane. It can generally be divided into hemodialysis and peritoneal dialysis. Frequent dialysis can cause kidney fibrosis and aggravate the condition.

However, due to moderate pathological damage, salt intake can be controlled and a low-salt or salt-free diet can be given depending on the presence or absence of hypertension and edema.

2. Vitamin intake: Patients with renal failure and high creatinine should choose foods rich in vitamin A, vitamin B2 and vitamin C. If the renal insufficiency only causes high creatinine level due to renal failure, but there is no oliguria or edema, the patient does not need to stop drinking salt and water, but should maintain a low-salt diet. If you have severe edema, high blood pressure or even heart failure, you should strictly limit your salt intake.

The concentration of serum creatinine is mainly determined by the filtration capacity of the glomerulus (glomerular filtration rate). As filtration capacity decreases, creatinine concentration increases. A blood creatinine level higher than normal usually means kidney damage. Blood creatinine can more accurately reflect the damage to the renal parenchyma, but it is not a sensitive indicator. Because blood creatinine will only increase significantly when the glomerular filtration rate drops to one-third of that of a normal person.

In fact, the kidneys have been severely damaged, and blood creatinine begins to rise significantly. The normal upper limit of plasma creatinine is about 100 micromoles/liter. Different hospitals have different testing standards, but none of them will exceed 120 micromoles/liter. Based on what you said, your kidney damage should be quite serious, so dialysis is the best way. However, your current creatinine is still far higher than the normal level and the purpose of dialysis has not been achieved, so you need to continue treatment.
