Peritoneal Dialysis<\/h1>\n\n\n\n

Peritoneal dialysis (per-ih-tuh-NEE-ul di-AL-uh-sis) is a way to remove waste products from the blood when the kidneys can no longer do their job adequately. During peritoneal dialysis, blood vessels in the stomach\u2019s abdominal lining, the peritoneum, filter much like the kidneys with the help of a dialysate fluid that goes in and out in cycles through a catheter in the abdomen.<\/p>\n\n\n\n

How Does Peritoneal Dialysis Work?<\/strong><\/h4>\n\n\n\n
<\/div>\n\n\n\n

PD uses the thin lining of the abdomen called the peritoneum as a filter. During treatments, a cleansing fluid called dialysate is cycled into the patient\u2019s abdomen through a small, flexible tube called a PD catheter.  <\/p>\n\n\n\n

The dialyzate absorbs or pulls extra waste and fluids from blood vessels in the abdominal lining into the peritoneal cavity where it stays in the abdomen for a specified amount of time (dwell time).  <\/p>\n\n\n\n

The PD machine then drains the fluid out of the abdomen and into a drain or waste bag and the excess wastes and fluids are removed from the body.  <\/p>\n\n\n\n

Then, fresh dialysate is sent back into the to peritoneum to clean the blood once more. This filling and draining process is called an exchange or cycle.<\/p>\n\n<\/div><\/div>\n\n

Is There More Than One Form of PD?<\/strong><\/h4>\n\n\n\n

There are two forms of peritoneal dialysis:<\/p>\n\n\n\n

<\/div>\n\n\n\n

Continuous Ambulatory Peritoneal Dialysis (CAPD)<\/strong><\/h4>\n\n\n\n

CAPD is peritoneal dialysis that can be done manually, without a machine, throughout the day. The patient fills his or her abdomen with dialysis solution and later drains the fluid. Gravity moves the fluid through the tube and into and out of the belly.<\/p>\n\n\n\n

Each exchange includes filling the abdomen with dialysate fluid, letting the fluid dwell in the abdomen, and then draining the fluid. Patients may need three to four exchanges during the day and one with a longer dwell time while sleeping. Exchanges can be done at home, work or any clean place. During CAPD, patients are free to go about their normal activities while the dialysis solution dwells in their abdomen between exchanges.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Continuous Cycling Peritoneal Dialysis (CCPD)<\/strong><\/h4>\n\n\n\n

With CCPD, which may also be called automated peritoneal dialysis (APD), a machine called an automated cycler performs three to five exchanges at night while the patient sleeps. The cycler automatically fills the abdomen with dialysis solution, allows it to dwell there and then drains it to a sterile drainage bag that is then discarded in the morning. This gives patients more flexibility during the day, but they must remain attached to the machine for 10 to 12 hours at night. In the morning, they begin one exchange with a dwell time that lasts the entire day.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The form of peritoneal dialysis that is best for each patient depends on their lifestyle, personal preferences and medical condition. Some patients may use a customized  program that combines the two forms.<\/p>\n\n\n\n
