Uremic dialysis is divided into two types: hemodialysis and peritoneal dialysis. Hemodialysis, commonly known as blood washing, is the process of drawing blood out of a uremic patient’s body, exchanging it through a dialyzer to expel toxins, and re-infusing the clean blood back into the body, called hemodialysis. The principle of peritoneal dialysis is to put a tube in the stomach and then pour peritoneal dialysis fluid into the abdominal cavity, and through the patient’s own peritoneal function, the blood and peritoneal dialysis fluid are exchanged and the toxins are expelled in the peritoneal dialysis fluid, and finally the peritoneal dialysis fluid is re-released out of the body to complete the detoxification process. Hemodialysis and peritoneal dialysis have their own advantages and disadvantages. Hemodialysis has a better ability to remove toxins, but it is less protective of the residual kidney and has a greater impact on the cardiovascular system. Membrane dialysis has better functional protection for the residual kidney and less impact on the cardiovascular system, but has less ability to remove toxins.
