| dialysance | The number of milliliters of blood completely cleared of any substance by an artificial kidney or by peritoneal dialysis in a unit of time; conventional clearance formulas are expressed as mm/min. Origin: fr. Dialysis (05 Mar 2000) |
| dialysate | That part of a mixture that passes through a dialyzing membrane. Synonym: diffusate. (05 Mar 2000) |
| dialysis | <technique> The process of separating crystalloids and colloids in solution by the difference in their rates of diffusion through a semipermeable membrane, crystalloids pass through readily, colloids very slowly or not at all. <technique> A medical procedure that uses a machine to filter waste products from the bloodstream and restore the bloods normal constituents. A necessary form of treatment in the patient with end-stage renal disease. In most circumstances, kidney dialysis is administered in a fixed schedule of three times per week. See: haemodialysis. Origin: Gr. Lysis = dissolution (26 Nov 1998) |
| dialysis dementia | A progressive (often fatal) diffuse encephalopathy which occurs in a few patients who undergo chronic haemodialysis, dementia is a key feature (27 Sep 1997) |
| dialysis disequilibrium syndrome | <syndrome> Nausea, vomiting, and hypertension, occasionally with convulsions, developing within several hours after starting haemodialysis for renal failure; apparently caused by too rapid removal of urea from the extracellular fluid compartment, with movement of water into cells, and cerebral oedema.

| dialysis encephalopathy syndrome | <syndrome> A progressive (often fatal) diffuse encephalopathy which occurs in a few patients who undergo chronic haemodialysis, dementia is a key feature (27 Sep 1997) |
| dialysis retinae | Congenital or traumatic separation of the peripheral sensory retina from the retinal pigment epithelium at the ora serrata, often causing a retinal detachment. Synonym: retinodialysis. (05 Mar 2000) |
| dialysis shunt | Arteriovenous shunt connecting the arterial and venous cannulas in arm or leg. (05 Mar 2000) |
| dialysis solutions | Solutions prepared for exchange across a semipermeable membrane of solutes below a molecular size determined by the cutoff threshold of the membrane material. (12 Dec 1998) |
| dialysis, peritoneal | Technique that uses the patient's own body tissues inside of the belly (abdominal cavity) to act as a filter. The intestines lie in the abdominal cavity, the space between the abdominal wall and the spine. A plastic tube called a dialysis catheter is placed through the abdominal wall into the abdominal cavity. A special fluid is then flushed into the abdominal cavity and washes around the intestines. The intestinal walls act as a filter between this fluid and the blood stream. By using different types of solutions, waste products and excess water can be removed from the body through this process.

| dialytic | Having the quality of unloosing or separating. Dialytic telescope, an achromatic telescope in which the coloured dispersion produced by a single object lens of crown glass is corrected by a smaller concave lens, or combination of lenses, of high dispersive power, placed at a distance in the narrower part of the converging cone of rays, usually near the middle of the tube. Origin: Gr, fr. See Dialysis. Source: Websters Dictionary (01 Mar 1998) |
