How does dialysis work? What is it needed for?

Removes waste, fluid: Dialysis takes over two important functions of the kidney: removing waste products & removing excess fluid. There are two basic techniques: hemodialysis and peritoneal dialysis. In hemodialysis, blood is removed from the body, circulated through a filter much like an oil filter, and returned to the blood stream. Peritoneal dialysis uses the peritoneal membrane in the abdomen. ...Read more

Dialysis (Definition)

Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more

Once I start dialysis will I have to quit work?

Once I start dialysis will I have to quit work?

Work on dialysis: Many patients on dialysis continue to work full time. The biggest obstacle tends to be the time spent doing dialysis, with schedules that can be fairly rigid. However now hemodialysis treatments can be done at home, or overnight in some centers, and cycled peritoneal dialysis can be done overnight at home. You're underlying medical condition is also a big factor in determining your ability to work. ...Read more

I would like help -- how dialysis work and why do we need it?

Dialysis machine: The purpose of a dialysis machine (D) and the artificial kidney (A) used on it is to replace the function of the kidneys of an end stage renal disease kidney patient which do not work. The A filter the blood of the patient removing waste products and water the diseased kidneys of the patient cannot do. This prevents the patient dying of kidney failure. The D does not affect the patient's kidneys. ...Read more

How can a dialysis machine work?

Filter, toxins: Dialysis does the work of kidney- removing fluids andtoxins. Blood from the patient flows on one side of the chamber and the dialysate solution which contains the optimal concentration of electrolytes on other side of the chamber. Electrolytes move along the concentration gradient, so toxins which are high in the blood, goes to the dialysate solution. ...Read more

How can a dialysis machine work and why is it used?

Artificial kidney: The principle of dialysis machine is hard to explain in 400 characters. Like a human kidney, it filters impure blood under pressure; excess water is removed; blood toxins (prea, phosphorus, and many others) diffuse out in to the dialysate (the clean artificial fluid put in to the machine); some electrolytes might diffuse back in to blood. The relatively clean blood diffuses is returnd to the patnt. ...Read more

How does a dialysis machine work and what is it used for?

Blood cleaning: Blood is pumped into a filter that allows toxins to pass into a salt solution that carries them away while delivering bicarbonate (sodium bicarbonate) and other needed minerals. Excess fluid can be removed with the filter also, the blood then returns to the patient without the toxins, with less water and with corrected acid base status. ...Read more

How does kidney dialysis work?

Filters blood.: It's a complicated process, but basically dialysis involves a filter called a dialyzer that the patient's blood passes through. Potentially harmful molecules in the blood are diffused across the filter membrane and eliminated as waste. Dialysis replaces some function of normal kidneys, but not all. It is better to stay healthy and prevent the need for dialysis if possible. ...Read more

How does peritoneal dialysis work?

How does peritoneal dialysis work?

Cleans blood: Fluid is infused into the abdomen. The fluid is separated from the abdominal organs by the peritoneal membrane. Toxins that build up in the blood will diffuse through the membrane into the fluid. This fluid is then drained from belly and that is how toxins are removed from your body. ...Read more

Why does kidney dialysis only work for a certain time?

Why does kidney dialysis only work for a certain time?

Duration of dialysis: The limits of kidney dialysis are due to dialysis access issues, inflammation from artificial membrane exposure, exposure to toxic medications to control the metabolic effects of kidney disease, and the complications of kidney failure that dialysis cannot totallyprevent, like cardiovascular disease, calcium, phosphorus vitamin d and PTH abnormalities, and peripheral or autonomic nerve damage. ...Read more

How does a fistula work to dialysis patient?

How does a fistula work to dialysis patient?

Arterial Diversion: When an artery is connected to a vein, the vein walls thicken and become muscular (due to the new high arterial pressure).
This makes finding the vein easier. More importantly, the large bore needles can be removed and pressure held, with clot forming in the muscular walls, to stop the bleeding. If the veins weren't muscular, putting the needle in and taking it out safely, aren't possible. ...Read more

How can the urinary system work in a patient going through dialysis?

How can the urinary system work in a patient going through dialysis?

Urinary tract and HD: The kidney structures that produce urine are still in place when a patient starts dialysis (d). Patients on dialysis can make urine from the kidney, however as times goes on the urine output decreases and after several years may stop all together. Although the kidney makes urine when patients on d, it's not a high quality urine, as the waste products that need to be eliminated are not, water is. ...Read more

How does a renal dialysis machine work?

Good question: Dialyzers are made of a polyurethane capsule within which hollow fibers or parallel membrane plates are suspended in dialysate (dialysis solution). The fibers or plates act as a semipermeable membrane across which blood and dialysate flow. By crossing this membrane, solutes and water move between a patient's intravascular compartment and the dialysis fluid contained within the dialyzer. ...Read more

How does automated peritoneal dialysis really work?

Automated by 2 ways: Some machines put liquid in the abdomen and pull it out by gravity i.e. The machine is located below the level of the bed on which the patient lies. The other does not use gravity but creates gentle negative pressure to suck the fluid back. You know the rest, the liquid that remained sometime inside the belly comes out with waste removed from the capillary circulation of the peritoneum by osmosis. ...Read more

What occurs if someone who doesn't need dialysis goes through the procedure?

Filter: Dialysis does the work of kidneys, acts like kidney filter. Removes the extra fluid and wastes, toxins that accumulate in the body. If one goes through the procedure when the kidney function is normal, it will cause electrolyte derangements, which may be life threatening. ...Read more

What would happen to someone who doesn't need dialysis but goes through it anyways?

Dialysis risks: Dialysis is a high risk procedure that should not be done unless necessary. The risks do not increase of its not needed, but if there is no benefit they are senseless. Complications include blood loss, both rapid and slow, dangerous blood pressure drops, reactions to the fluid or membranes used, and increased risks of infection. While dialysis is generally safe, why risk it if no need? ...Read more

Is there anything I should be doing right now to assist me in preparation for dialysis when the time comes? (the do's and don't s). Thank you.

Is there anything I should be doing right now to assist me in preparation for dialysis when the time comes? (the do's and don't s). Thank you.

Yes: If you have renal insufficiency ("pre-dialysis" kidney disease) you should consider getting a fistula placed. Since you have some klidney function you are a better surgical candidate, will heal better, and can get a native vein fistula (the best kind). Don't wait until you start dialysis because you may need a catheter (which is not good). ...Read more

What if a dialysis patient takes a medication or something that isn't dialyzable and can't be removed by dialysis?

See below : Prescribing for pts on dialysis can be challenging. Many drugs are not cleared by the kidneys. The drug’s clearance and therapeutic index determine if a dose adjustment is needed. When prescribing for pts on dialysis, it is essential to consult a reference guide to determine if the drug is subject to renal clearance and requires a dose adjustment. Best to discuss with a nephrologist. ...Read more

What is dialysis?

Kidney failure treat: Kidneys are vital to keep the body in a stable condition, removing waste products, keeping water and electrolytes within very narrow range required for normal function of all the organs. With kidney failure this can be done by dialysis either hemodialysis where blood is filtered through an external machine or using the lining od the abdomen (peritoneal membrane) as a filtering mechanism. ...Read more

How is dialysis performed?

Dialysis: Dialysis can be done through the blood (hemodialysis) or through the abdomen (peritoneal dialysis). Hemodialysis involves passing the blood across and filter to purify it / remove toxins and remove water. Peritoneal dialysis takes advantage of the membrane within the abdomen to act as a filter. In either case toxins are removed from the blood stream. ...Read more

What exactly will dialysis do?

Clean blood: Dialysis removes waste products from the blood and extra fluids to replace the function of the kidneys and prolong life. Without it death is usually eminent in a few months more or less. The quality of life on dialysis is less than that with functioning kidneys due to substantial fatigue and other medical problems and medications. ...Read more
