Types of Dialysis: Hemodialysis vs. Peritoneal Dialysis
Hemodialysis is one of the management and treatment options for advanced kidney failure. It allows you to lead a productive life even when your kidneys are failing. A machine performs the functions of kidneys by filtering wastes, fluids, and salts from your blood since the kidneys cannot do them properly.
During hemodialysis, you follow a strict treatment plan, and you have to change aspects of your daily diet. You will also have medication that has to be taken regularly. At Pedes Orange County, we understand how vital this treatment is to you and the sacrifices you are making. We will be your health partner so that you do not shoulder this burden alone but with our health care team.
Hemodialysis Access Types
There are three kinds of vascular accesses;
- Arteriovenous fistula: It is a connection between an artery and a vein that is created surgically. It is often on the arm you use less often. Because of the safety and effectiveness levels it offers, it is usually the preferred kind of access.
- Arteriovenous graft: A path between an artery and a vein created using a synthetic tube known as a graft. It is the alternative used if the patient’s vessels are too small to create an AV fistula.
- Central Venous Catheter: It is an option used in cases where emergency hemodialysis is required. Doctors insert a plastic tube known as a catheter in a large vein either in the groin or neck for access. The catheter is only temporary.
In peritoneal dialysis, doctors surgically implant a catheter in your belly area. They then flow a special purifying fluid called dialysate into your abdomen through the catheter. The dialysate then absorbs the waste from the bloodstream, and it is drawn from the abdomen.
There are different types of peritoneal dialysis, but the two main ones are Continuous Ambulatory Peritoneal dialysis and Continuous Cycler-assisted Peritoneal dialysis. With the first option, your abdomen is filled and drained with dialysate several times each day. With Cycler-assisted peritoneal dialysis, however, a machine is the one cycling the fluid in and out of your body, and it often happens at night as you sleep.
