What is the Purpose of Kidney Dialysis
The main purpose of kidney dialysis is to perform the function of the kidneys artificially, using a machine. People usually go for kidney dialysis when they are suffering from a critical condition like end-stage renal disease (ESRD). In this situation the kidneys are completely damaged and can no longer do what they are supposed to do. In haemodialysis, the dialysis is done by inserting a needle into the blood vessel, the needle already being attached to the dialysis machine with the help of a tube. Once that is done, the blood is transferred from the blood vessel and stored into the dialysis machine where it is filtered. Once the waste materials and fluids have been extracted, the filtered blood is again sent back to the body. This is considered to be the most commonly used technique for kidney dialysis. The other type of approach is known as the peritoneal dialysis wherein the blood is filtered using the peritoneum membrane inside your abdomen. A fluid known as dialysate is passed into the peritoneal cavity of the body with the help of a catheter which is attached inside the abdomen by making an incision. Then the blood vessels present in the peritoneum filters the blood and passes on the waste materials to the dialysis fluid which is then drained out via the catheter. The next approach is the hemofiltration wherein a device known as a hemofilter is used as a dialyzer and the blood is passed through the hemofilter wherein it filters the waste products and materials and returns the filtered blood back into the body along with certain replacement fluids. The replacement fluids helps in balancing the electrolytes lost in the process. And last but not the least, the other type of approach is known as the hemodialfiltration, which is a combination of hemodialysis and hemofiltration.
After understanding the process of kidney dialysis and the different approaches, you would have understood that the purpose of kidney dialysis is nothing else but to carry out the process of filtration, even if the kidneys are no longer able to perform that function. Although there are various complications associated with kidney dialysis, like fatigue, weakness, anemia, sleeping problems, fluid accumulation and so on, it still is considered to be a better option over not going for it at all. Apart from performing the kidney function, some doctors also advice to go for a kidney dialysis in case of poisoning or drug overdose so that the excess drug or poison can be drained out of the system.
