dialysis

[di-al´ĭ-sis] (Gr.)

1. the diffusion of solute molecules through a semipermeable membrane, normally passing from the side of higher concentration to that of lower. A semipermeable membrane is one that allows the passage of certain smaller molecules of such crystalloids as glucose and urea, but prevents passage of larger molecules such as the colloidal plasma proteins and protoplasm. adj., adj dialyt´ic.

2. hemodialysis.

continuous ambulatory peritoneal dialysis (CAPD) peritoneal dialysis involving the continuous presence of dialysis solution in the peritoneal cavity; see discussion at peritoneal dialysis.

continuous cycling peritoneal dialysis (CCPD) a procedure similar to continuous ambulatory peritoneal dialysis but taking place at night, using a machine to make several fluid exchanges automatically. See discussion at peritoneal dialysis.

dialysis dysequilibrium syndrome a condition occasionally seen following overly rapid hemodialysis, characterized by increased intracranial pressure that causes nausea, headache, vomiting, restlessness, and a decreased level of consciousness. The neurological complications may lead to coma and death if not treated. The cause of this syndrome is thought to be the rapid decrease in the blood urea nitrogen that accompanies dialysis. Called also dialysis dysequilibrium.

extracorporeal dialysis dialysis by a hemodialyzer; see also hemodialysis.

intermittent peritoneal dialysis (IPD) an older form of peritoneal dialysis in which dialysis solution is infused into the peritoneal cavity, allowed to equilibrate for 10 to 20 minutes, and then drained out. See discussion at peritoneal dialysis.

kidney dialysis hemodialysis.
