During peritoneal dialysis, the dialysate flows through a catheter into part of the abdomen. The peritoneum, which is the lining of your abdomen, acts as a natural filter and removes the waste products from your blood. However, this type of dialysis is not ideal for all patients. There are two types of peritoneal dialysis: continuous ambulatory peritoneal dialysis CAPD and automated peritoneal dialysis. With continuous ambulatory peritoneal dialysis CAPD , the abdomen is filled with dialysate.
The patient lets it stay in the abdomen for a prescribed dwell time before draining the fluid. Gravity moves the fluid through the catheter without machine assistance. Exchanges can be done pretty much anywhere that is clean and sanitized. Patients can continue their activities while the dialysate dwells in the abdomen. Automated peritoneal dialysis is also known as continuous cycling peritoneal dialysis CCPD.
This type of dialysis uses a machine that cycles through multiple exchanges at night while you sleep. The machine fills your abdomen with dialysate and allows it to dwell there for a while before draining into a sterile bag. In the morning, you empty the bag. If you are using automated peritoneal dialysis, you must remain attached to the machine for around hours each night.
However, you do not need to connect to the machine during the day because you start each morning with a dwell time that lasts for the entire day. So which treatment is right for you when comparing hemodialysis vs peritoneal dialysis? Dialysis is a way of cleaning your blood when your kidneys can no longer do the job. It gets rid of your body's wastes, extra salt and water, and helps to control your blood pressure. There are two kinds of dialysis.
In hemodialysis, blood is pumped out of your body to an artificial kidney machine, and returned to your body by tubes that connect you to the machine. In peritoneal dialysis, the inside lining of your own belly acts as a natural filter. Wastes are taken out by means of a cleansing fluid called dialysate, which is washed in and out of your belly in cycles. A soft plastic tube catheter is placed in your belly by surgery.
A sterile cleansing fluid is put into your belly through this catheter. After the filtering process is finished, the fluid leaves your body through the catheter. However, the number of treatments and the way the treatments are done make each method different. CAPD is "continuous," machine-free and done while you go about your normal activities such as work or school. You do the treatment by placing about two quarts of cleansing fluid into your belly and later draining it.
This is done by hooking up a plastic bag of cleansing fluid to the tube in your belly. Raising the plastic bag to shoulder level causes gravity to pull the fluid into your belly. When empty, the plastic bag is removed and thrown away. Hemodialysis is done with the help of an apparatus called a dialyzer. On the other hand, the latter uses a combination of the lining of the peritoneal membrane abdominal cavity and a solution. Your doctor will need to create a site for the flow of blood in and out of your body before you can start treatments.
A machine, which you will be connected to by tubes attached to your blood vessels, will be used to clean your blood. Since the elimination of waste is done by machine, you will have to go to a hospital or dialysis center on a set schedule. Usually, this treatment is done three days each week and takes around three to five hours per day.
There is an option to do dialysis at home, but it will require training for you and at least one other person assigned to help you. Certain changes will also be required for your home in order for the equipment to work. Since the machine is in your home, you can set your own schedule for dialysis but it has to be more frequent, although the sessions will be shorter.
For instance, you can have a daily session lasting two to three hours.
