What is dialysis?
Dialysis is a life-saving medical procedure used by kidney specialists to treat children whose kidneys have failed.
Why is dialysis needed in kidney failure?
The main function of the kidneys is to keep the blood clean and remove all the excess water, salts, and chemicals that are not needed or are harmful to the body. These are thrown out of the body through urine. Normally, we have two kidneys to do his work. The kidneys work 24 x 7 and clean the blood 4 to 5 times every hour.
When kidneys are damaged, they cannot clean the blood efficiently. Hence, unwanted water, salt, and bad chemicals accumulate in the blood. This can lead to ill effects on other organs like the blood, heart, lungs, and brain. If this is not recognized and treated in time, it can even lead to death.

How is dialysis done?
Dialysis can be done in two different ways.

Blood of the patient is pumped through a filter that removes the excess water and chemicals and returns the cleaned blood back to the patient. The dialysis is done for 4 hours three times a week.
2. Peritoneal dialysis or PD is a simpler procedure and quite commonly used in children especially the smaller children. It can be done even in new-born babies. A soft PD catheter or tube is placed inside the child’s abdomen. Dialysis is done like a washout. A measured quantity of special dialysis fluid is run into the abdomen through the catheter and allowed to remain there for a few hours. During this dwell period, impurities from the blood flow into the dialysis fluid. After a few hours, the fluid with the impurities is drained out. The process is then repeated 3 to 4 times in the day. As this is a simple and gentler procedure, it can be easily done by the mother or father at home.
