In medical field, Dialysis is referred to a procedure to provide an artificial replacement for the kidney that has stopped functioning in those who have got a renal failure. A brief description of the types of dialysis is given here. There are five types, three primary and two secondary.
Hemodialysis
In hemodialysis, the blood of the patient is pumped into blood compartment of a dialyzer while it is exposed to a partially permeable membrane. Blood flows into the thousands of fibers a dialyzer is composed of and dialysis solution flows around the fibers. Water and waste matters circulated between these two solutions. After cleansing blood it is pumped back to the body via the circuit. Hydrostatic pressure across the dialyzer membrane is increased for the purpose of ultra filtration.
Peritoneal dialysis
In this type, the abdominal cavity around the intestines called peritoneal cavity is supplied with a sterile solution that has glucose in it. Peritoneal membrane also known as peritoneum composed of a layer of tissue having blood vessels is semi-permeable membrane. These blood vessels also surround other abdominal organs such as liver, spleen, stomach and the intestines. Through this dialysis, wastes are absorbed into the dialyzer then drained outside the body, through the tube. This cycle is repeated four to five times in every session.
Intestinal dialysis
In this type, the patient is given soluble fibers, like acacia fiber through diet that is easily digested by the bacteria in the colon. This in turn increases nitrogen content which is excreted out from the body in feces. Alternatively, 1 to 1.5 liters of non absorbable solutions are taken throughout the day after four hours of interval. The solutions comprise of mannitol or polyethylene glycol.
Hemofiltration
This is similar to hemodialysis but works on different principles. It includes the use of a pressure gradient instead of dialysate when blood is pumped into a hemofilter.
Hemodialfiltration
This is a combination of hemofiltration and hemodialysis and the level of effectiveness is double.
