• kidney
  • This type of dialysis achieves the extracorporeal removal of waste products such as creatinine and urea and free water from the blood when the kidneys are in a state of kidney failure. (wikipedia.org)
  • Fat-soluble vitamins include vitamins A, D, E, and K. Excessive amounts of these vitamins can be harmful for people with kidney failure because they can build up in the body and become toxic so they are not generally supplemented in dialysis patients. (wikipedia.org)

  • Dialysis is used as a temporary measure in either acute kidney injury or in those awaiting kidney transplant and as a permanent measure in those for whom a transplant is not indicated or not possible. (wikipedia.org)
  • Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. (wikipedia.org)
  • fluid
  • These side effects can be avoided and/or their severity lessened by limiting fluid intake between treatments or increasing the dose of dialysis e.g. dialyzing more often or longer per treatment than the standard three times a week, 3-4 hours per treatment schedule. (wikipedia.org)
  • In the United States, the substitution fluid used in CHF or CHDF is commercially prepared, prepackaged, and sterile (or sometimes is prepared in the local hospital pharmacy), avoiding regulatory issues of on-line creation of replacement fluid from dialysis solution. (wikipedia.org)
  • Dialysis treatments replace some of these functions through diffusion (waste removal) and ultrafiltration (fluid removal). (wikipedia.org)
  • Dialysis works on the principles of the osmosis of solutes and ultrafiltration of fluid across a semi-permeable membrane. (wikipedia.org)
  • molecules
  • In research laboratories, dialysis technique can also be used to separate molecules based on their size. (wikipedia.org)
  • In the context of life science research, the most common application of dialysis is for the removal of unwanted small molecules such as salts, reducing agents, or dyes from larger macromolecules such as proteins, DNA, or polysaccharides. (wikipedia.org)
  • Diffusion is the random, thermal movement of molecules in solution (Brownian motion) that leads to the net movement of molecules from an area of higher concentration to a lower concentration until equilibrium is reached. (wikipedia.org)
  • Dialysis can be used to either introduce or remove small molecules from a sample, because small molecules move freely across the membrane in both directions. (wikipedia.org)
  • Summary: Dialysis is the process used to change the matrix of molecules in a sample by differentiating molecules by the classification of size. (wikipedia.org)
  • Separating molecules in a solution by dialysis is a straightforward process. (wikipedia.org)
  • Although dialyzing a sample is relatively simple, a universal dialysis procedure for all applications cannot be provided due to the following variables: The sample volume The size of the molecules being separated The membrane used The geometry of the membrane, which affects the diffusion distance Additionally, the dialysis endpoint is somewhat subjective and application specific. (wikipedia.org)
  • minerals
  • However, many patients on dialysis must follow dietary restrictions, making it difficult for them to get the necessary amounts of certain vitamins and minerals to stay healthy. (wikipedia.org)
  • In addition to this, many vitamins and minerals are lost during the process of dialysis. (wikipedia.org)
  • In general, the following vitamins and minerals are supplemented in dialysis patients: B vitamins- Water-soluble vitamins that play a role in red blood cell development to prevent anemia and contribute to metabolism to help change the foods you eat into energy. (wikipedia.org)
  • It can be very confusing trying to determine which vitamins and minerals need to be supplemented and which do not so it is important for dialysis patients to speak with a doctor before making any changes to their nutritional plan. (wikipedia.org)
  • osmotic
  • The osmotic activity of icodextrin keeps the solution inside the peritoneum for three to four days, separating tissues and thus reducing adhesion between them when fibrin is formed after a surgery. (wikipedia.org)
  • buffer
  • For another solute, bicarbonate, dialysis solution level is set at a slightly higher level than in normal blood, to encourage diffusion of bicarbonate into the blood, to act as a pH buffer to neutralize the metabolic acidosis that is often present in these patients. (wikipedia.org)
  • production
  • The MWCO of a membrane is the result of the number and average size of the pores created during production of the dialysis membrane. (wikipedia.org)
  • night
  • There is also interest in nocturnal dialysis, which involves dialyzing a patient, usually at home, for 8-10 hours per night, 3-6 nights per week. (wikipedia.org)
