  Dialysis - Wikipedia, the free encyclopedia
Dialysis may be used for very sick patients who have suddenly lost their kidney function (acute renal failure) or for quite stable patients who have permanently lost their kidney function (end stage renal failure).
By altering the composition of the dialysis fluid, the concentrations of undesired solutes (chiefly potassium and urea) in the fluid are low, but the desired solutes (for example sodium) are at their natural concentration found in healthy blood, or in the case of bicarbonate, greater, to neutralise the acidosis that is often present.
In peritoneal dialysis, a special solution is run through a tube into the peritoneal cavity, the abdominal body cavity around the intestine, where the peritoneal membrane acts as a semipermeable membrane.

 Global Dialysis: What is Dialysis
In acute renal failure, (renal) dialysis is generally initiated when the renal function has deteriorated to an extent that it is threatening the body's physiology.
The bag of dialysis fluid is removed from the protective packaging, and is hung from an IV stand or other elevated location, such as a coat hook.
Intermittent dialysis is associated with a steep drop in blood pressure, and dialysis patients are warned not to travel without assistance.

 Dialysis
Dialysis is a method of removing toxic substances (impurities or wastes) from the blood when the kidneys are unable to do so.

Dialysis is one way of replacing the critical function of the kidneys, or renal replacement therapy, thereby sustaining life.
Peritoneal dialysis utilizes the peritoneal membrane, which is the lining of the abdominal cavity.
This is how peritoneal dialysis is performed: a solution, called the dialysate, is fed into the peritoneal cavity (the spaces around the intestines and other organs) via a small tube (catheter) that has been placed there in a minor surgical procedure.

 Peritoneal dialysis - Wikipedia, the free encyclopedia
Peritoneal dialysis works on the principle that the peritoneal membrane that surrounds the intestine, can act as a natural semipermeable membrane (see dialysis), and that if a specially formulated dialysis fluid is instilled around the membrane then dialysis can occur, by diffusion.
Dialysis fluid is instilled via a peritoneal dialysis catheter, (the most common type is called a Tenckhoff Catheter) which is placed in the patient's abdomen, running from the peritoneum out to the surface, near the navel.
Peritoneal dialysis is typically done in the patient's home and workplace, but can be done almost anywhere; a clean area to work, a way to elevate the bag of dialysis fluid and a method of warming the fluid are all that is needed.

Background: Dialysis encephalopathy is a progressive and frequently fatal neurologic disease observed almost exclusively in patients who are being treated with long-term hemodialysis.

 Kidney Dialysis
In the kidney, the blood undergoes filtration and dialysis to separate the particles that will be removed from the body (through the ureter to the bladder) from those that will be returned to the circulating blood (through the renal vein).
The tubule functions as a dialysis unit, in which the fluid inside the tubule is the internal solution and the blood (in capillaries surrounding the tubule) acts as the external solution.
Thus, artificial kidney dialysis uses the same chemical principles that are used naturally in the kidneys to maintain the chemical composition of the blood.

 USATODAY.com - Science waking up to while-you-sleep dialysis   (Site not responding. Last check: 2007-11-07)
His team of researchers followed 14 patients with end-stage kidney disease for a year and found "encouraging" results from their use of nighttime home dialysis, with improvements in cardiovascular markers not achieved by standard, three-times-a-week clinic-based dialysis.
That's why the U.S. National Institutes of Health is helping sponsor the first major randomized, controlled study of both nocturnal dialysis and a second alternative protocol, "short daily dialysis," where patients visit the dialysis clinic six times per week, but for an average of just 2 hours a session.
Chan's research also found that, unlike standard dialysis, sleep-time dialysis prevented the buildup of calcium phosphate within arteries — a major risk factor for cardiovascular disease in these patients.
