How does uremia dialysis picture?
summary
Hemodialysis is an immediate treatment to alleviate the crisis of uremia. Is there any other treatment for uremia besides dialysis? Due to the good effect of hemodialysis treatment in the short term, many people want to know how long hemodialysis can last. In fact, this problem varies from person to person! There are advantages and disadvantages. How many years is it long? Two or three years is it short. How does uremia dialysis picture? Let's talk about it.
How does uremia dialysis picture?
What is the working process of dialysis? Dialysis refers to the process of solute passing from one side of semipermeable membrane to the other. Any natural (e.g. peritoneum) or man-made semipermeable membrane can move solutes from one side of the membrane to the other through dispersion and convection as long as the membrane contains pore size through which solutes of a certain size can pass. Hemodialysis is based on the principle of semipermeable membrane. The patient's blood and dialysate are introduced into the dialyzer at the same time. The dialyzer moves in the opposite direction on both sides of the dialyzer membrane. By virtue of the solubility gradient, osmotic gradient and water pressure gradient on both sides of the semipermeable membrane, the toxin is removed through dispersion, convection and adsorption; Through ultrafiltration and osmosis, the excess water in the body is removed; At the same time, supplement needed substances, correct electrolyte, acid-base balance disorder.
What is the effect of dialysis on the kidney? Dialysis is to replace the kidney. When the patient enters the uremic stage, the kidney of the patient should be damaged by more than 90%. If there is no alternative treatment, the toxin will remain in the body. The "poison" in the body includes metabolites, drugs and exogenous poisons. As long as its atomic weight or molecular weight is appropriate, it can be removed out of the body through dialysis. Its basic principle is dispersion and convection.
What harm does long-term dialysis have? Long term nephrotic dialysis can produce dependence, nephrology expert Mo Feifan said. Dialysis is only an auxiliary tool for the treatment of the kidney, which can only relieve the pain as soon as possible and can not remove the root. For a long time, dialysis will produce dependence on the human body, and it will have side effects on the human body after a long time. Kidney dialysis can save people, but it can't cure them. Dialysis can timely and quickly detoxify the body toxin, but the complications after dialysis are many and serious, as time goes by, it will also be life-threatening.
matters needing attention
If after dialysis, the kidney will slowly start to be used no longer, and it will completely lose function after a long time, then there will be no way to treat and repair it. Kidney dialysis will make the kidney loss gradually. If the patients only rely on dialysis for a long time, the only function of the kidney will shrink and be scrapped because they don't use it for a long time, and they can no longer have fertility after dialysis.
