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.
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.

renal dialysis hemodialysis.

dialysis

(di-al'i-sis) ('i-sez?) plural.dialyses [ dia- + -lysis]
1. The passage of a solute through a membrane.
2. The diffusion of blood across a semipermeable membrane to remove toxic materials and to maintain fluid, electrolyte, and acid-base balance in cases of impaired kidney function or absence of the kidneys. hemodialysis;

chronic ambulatory peritoneal dialysis

Continuous ambulatory peritoneal dialysis.

continuous ambulatory peritoneal dialysis

Abbreviation: CAPD
Dialysis in which fluid is infused into the peritoneum through an implanted catheter and then drained from the body after absorbing metabolic toxins. The peritoneal lining serves as the dialytic membrane. CAPD is an alternative to hemodialysis for patients with end-stage renal disease. It removes fluids, electrolytes, and nitrogen-containing wastes by osmosis but is less efficient than hemodialysis. Scrupulous antiseptic technique is needed to avoid introducing infectious microorganisms into the dialysate and peritoneum. The technique has several benefits: it can be performed at home by patients (increasing their autonomy); it avoids the hypotension sometimes associated with hemodialysis; and it is better tolerated than hemodialysis because it is less likely to produce rapid shifts in the concentration of urea, electrolytes, and other solutes in the bloodstream. Synonym: chronic ambulatory peritoneal dialysis See: peritoneal dialysis

continuous cyclic peritoneal dialysis

Abbreviation: CCPD
Dialysis performed every night with fluid remaining in the peritoneal cavity until the next night.

intermittent peritoneal dialysis

Abbreviation: IPD
Dialysis using automated equipment, often performed overnight. The fluid is drained from the peritoneal cavity at the end of the treatment.

peritoneal dialysis

Dialysis in which the lining of the peritoneal cavity is used as the dialyzing membrane, requiring less complex equipment and less specialized personnel than hemodialysis, little or no heparin, no blood loss, and minimal cardiovascular stress. Dialyzing fluid introduced into the peritoneal cavity is left to dwell there for a specified time and then passively drained.

Peritoneal dialysis is used to treat renal failure and, less commonly, certain types of poisoning, hypothermia, or heatstroke.

CAUTION!

Although peritoneal dialysis may be performed anywhere by the patient, allowing him or her to be independent, regular follow-up with health care professionals is needed to optimize its safety and effectiveness.

Patient care

Strict aseptic technique is maintained throughout the procedure. The patient is observed for signs of peritonitis, pain, respiratory difficulty, and low blood pressure. Peritoneal dialysis requires a semipermanent implantation of a catheter through the abdominal wall into the peritoneum, just below the umbilicus. Patients with a history of abdominal surgeries may have scarring; they are not candidates for peritoneal dialysis and should use hemodialysis, instead. The patient's understanding of the procedure and the reason for it, care of the peritoneal catheter, and symptoms of infection are verified. Medication schedule can be changed before and after dialysis. Urea clearance is less than with hemodialysis (60%), and excessive protein loss may necessitate a high protein diet. The patient's ability to adjust lifestyle to provide a balance of adequate rest and activity is evaluated.

renal dialysis

Hemodialysis.

Patient discussion about renal dialysis

Q. why the renal doctor told my husband that he needs to eat a dozen of egg a week for protein,how it will help? it won`t afect his cholesterol,also i would like to know what role the protein plays on his treatment and what other foot its rich in protein that he can can take,without causing problems to his health.

A. if i understand correctly, your husband is diabetic. like my grandfather he probably developed a "Diabetic nephropathy" which is a long name to: kidney being destroyed because of blood vessels clotted by diabetes. because of that destruction the kidneys allow protein to go out in the urine. this is a dangerous situation,a protein in the name of "albomin" helps our blood to hold fluids in blood vessels. without it fluid will leave the blood and go to our organs. not a good situation. so he needs a lot of proteins.
here is a list of a 100 protein rich foods:
