Dialysis is needed only when a patient develops end-stage kidney failure. Dialysis cleans waste, salt, and extra water that prevents all from building up inside the body, not only cleaning up but allowing a safe level of chemicals in your blood such as potassium, sodium, and bicarbonate. It helps to control blood pressure also. High blood pressure is a condition detrimental to someone with kidney failure. You have lost 85 to 90% of your kidney function if it is decided you need to be on dialysis. Kidney failure is not permanent although it can also be permanent. Dialysis can be done in a hospital, or a dialysis unit not attached to one. Dialysis can be done at home as well if you have the equipment necessary.
Dialysis can even be done at home using a Baxter Dialysis Machine. Dialysis is done at home while there are two types of dialysis, hemodialysis, and peritoneal dialysis. Hemodialysis is about using an artificial kidney to remove waste, chemicals, and fluid from the blood. To get blood into the artificial kidney, the doctor does minor surgery to your arm or leg to make an access, which means joining an artery to a vein under the skin. This makes a bigger blood vessel called a fistula. If you cannot have a fistula, then the doctor makes a graft to join an artery and a vein under your skin.
Another option is to use a catheter entering a large vein in your neck, access that is temporary but may be used with regard to long-term treatments. Dialysis length of treatment is determined based on how well your kidneys work, how much fluid weight you gain between treatments, how much waste material you have in your body, how big you are, and the type of artificial kidney that is used for this situation. Peritoneal dialysis is different from hemodialysis in that your body is cleaned inside your body. There will be surgery done to put a plastic catheter into your abdomen as the blood stays in the arteries and veins that line the peritoneal cavity as there are two kinds of peritoneal dialysis, such as Continuous Ambulatory Peritoneal Dialysis known as (CAPD), done without machines that you can do four or five times a day at work.
A bag of dialysate or two quarts stays put in the bag until it is thrown away, even as you go about your usual activities at work, school, or at home. Automated Peritoneal Dialysis (APD), is done at home through a machine called the cycler, which is similar to CAPD except that exchanges occur when each cycle lasts 1- ½ hours with the exchange being made while you sleep. Dialysis does not cure kidney disease. As has been covered, dialysis is a procedure to clean the kidneys, if they are in kidney failure, meaning that dialysate and your blood flow through the device but do not touch each other. Blood may or may not clot moving through the blood tubing even as heparin is injected.
