Kidney Dialysis is a treatment that does some of the important things done by healthy kidneys. It is needed when your very own kidneys can no more care for your body’s demands.
When is dialysis required?
You need dialysis when you establish end phase kidney failing – often by the time you lose concerning 85 to 90 percent of your kidney function and also have a GFR of <15.
What does dialysis do?
When your kidneys fail, dialysis keeps your body in balance by:.
Removing waste, salt and extra water to prevent them from building up in the body.
Keeping a safe level of certain chemicals in your blood, such as potassium, sodium and bicarbonate.
Helping to control blood pressure.
Usually, but not always. Some kinds of acute kidney failure get better after treatment. In some cases of acute kidney failure, dialysis may only be needed for a short time until the kidneys get better.
In chronic or end stage kidney failure, your kidneys do not get better and you will need dialysis for the rest of your life. If your doctor says you are a candidate, you may choose to be placed on a waiting list for a new kidney.
Where is dialysis done?
Dialysis can be done in a hospital, in a dialysis unit that is not part of a hospital, or at home. You and your doctor will decide which place is best, based on your medical condition and your wishes.
Are there different types of dialysis?
Yes, there are two types of kidney dialysis – hemodialysis and peritoneal dialysis.
What is hemodialysis?
In hemodialysis, an artificial kidney (hemodialyzer) is used to remove waste and extra chemicals and fluid from your blood. To get your blood into the artificial kidney, the doctor needs to make an access (entrance) into your blood vessels. This is done by minor surgery to your arm or leg.
Sometimes, an access is made by joining an artery to a vein under your skin to make a bigger blood vessel called a fistula.
How long do hemodialysis treatments last?
Time required for your dialysis depends upon:.
How well your kidneys work.
Just how much fluid weight you gain in between treatments.
Just how much waste you have in your body.
How big you are.
The sort of fabricated kidney utilized.
Often, each hemodialysis treatment lasts about 4 hours and also is done 3 times each week.
A sort of hemodialysis called high-flux dialysis may take less time. You can talk to your doctor to view if this is an appropriate treatment for you.
What is peritoneal kidney dialysis as well as how does it work?
In this sort of dialysis, your blood is washed inside your body. The doctor will do surgery to place a plastic tube called a catheter into your abdomen (belly) to make an access. During the treatment, your abdominal area (called the peritoneal cavity) is gradually filled with dialysate through the catheter. The blood stays in the arteries as well as capillaries that line your peritoneal tooth cavity. Additional fluid and waste products are dragged out of your blood as well as into the dialysate. There are two major kinds of peritoneal dialysis.
What are the different sorts of peritoneal dialysis and also how do they work?
There are several types of peritoneal dialysis but two major ones are:.
Continuous Ambulatory Peritoneal Dialysis (CAPD) and Automated Peritoneal Dialysis (APD).
Continuous Ambulatory Peritoneal Dialysis (CAPD) is the only sort of peritoneal dialysis that is done without machines. You do this on your own, typically four or five times a day at home and/or at the office. You put a bag of dialysate (about two quarts) into your peritoneal tooth cavity through the catheter. The dialysate stays there for regarding four or five hours before it is drained back into the bag and gotten rid of. This is called an exchange. You use a new bag of dialysate each time you do an exchange. While the dialysate is in your peritoneal cavity, you can tackle your common tasks at the office, at school or at home.
Automated Peritoneal Dialysis (APD) normally is done at home using a special machine called a cycler. This is similar to CAPD other than that a variety of patterns (exchanges) take place. Each cycle typically lasts 1-1/2 hours and also exchanges are done throughout the night while you sleep.
