What is renal dialysis

summary

Some time ago, my mother said that an elder had kidney problems and needed renal dialysis, so she soon took me to the hospital to visit him. During this period, I also learned about the situation and problems of renal dialysis. Today, let me talk about what is renal dialysis.

What is renal dialysis

First: dialysis is kidney filtration of blood, remove waste material. If the kidney fails, the waste will accumulate in the body and eventually poison the human body. Renal dialysis, also known as artificial kidney, is also called hemodialysis or kidney washing. It is equivalent to that all the blood in your body is transfused to the external machine for filtration, and it takes more than four and a half hours for a dialysis. For people with poor renal function, dialysis can only be maintained temporarily, and eventually the kidney has to be changed.

Second: there are two kinds of renal dialysis, one is hemodialysis, the other is peritoneal dialysis. At present, hemodialysis is widely used. Nephritis is a common kidney disease, most of which do not need dialysis, only when patients with nephritis complicated with uremia need dialysis treatment. It is a kind of blood purification technology. Hemodialysis can alleviate the symptoms and prolong the survival period of patients. Because renal dialysis relies on the instrument for extracorporeal circulation, the patient has a certain risk.

Third: dialysis therapy is based on the principle of membrane balance of semipermeable membrane, using dialysate composed of certain concentration of electrolyte and glucose and metabolites accumulated in blood, water and electrolyte for osmotic exchange, so as to achieve the purpose of treatment. Hemodialysis (also known as artificial kidney) and peritoneal dialysis are usually used in patients with renal failure. The general condition of patients after dialysis can be improved.

matters needing attention

Therefore, patients after renal dialysis must pay attention to daily maintenance and nursing, avoid overwork, pay attention to rest and relax, adjust diet structure, pay attention to supplement protein and nutrients, avoid excessive intake of cholesterol, quit smoking and alcohol, and develop good living habits.
