Osmosis Vs. Dialysis
Different filters!: Both hemodialysis and peritoneal dialysis remove toxins and excess fluid in kidney failure. In hemodialysis, blood runs out of the body through IV tubing, and into a machine - where it's filtered before returning to the body. In peritoneal dialysis, dialysis fluid is introduced into the abdomen, where it interfaces with blood by way of the peritoneal membrane. Read 'help! i need dialysis' by agar. ...Read more
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
Not the same: Dialysis removes about 80% of the impurities that build up, but not all of them as would a normal kidney. The kidney is more of a selective filter. The normal kidney also produces hormones--small molecules, that aid in things such red blood cell formation, and calcium metabolism. ...Read more
Both means to an end: Hemodialysis and peritoneal dialysis both accomplish filtering the blood of impurities. Hemodialysis is done by rapidly filtering the blood through a machine using a catheter or a surgically created access. Sessions usually last four hours and are done three times a week. Peritoneal dialysis is done by instilling special fluid into the abdomen and overnight the impurities are removed. ...Read more
Less cardiac risk: The most important advantage of kidney transplant over dialysis is that it reduces the excess risk of cardiac mortality from kidney failure. However it is an invasive procedure with its own risks from the surgical procedure and the side effects of the drugs needed to prevent rejection. This is the reason for extensive testing and counseling before transplantation. ...Read more
Big difference: Both are ways to treat kidney failure. Dialysis is the cleansing of the blood of most impurities that build up without a functioning kidney. It can be done through a machine with filters or through a tube in the peritoneum (abdomen) to exchange fluids. A transplant means surgically implanting a new kidney to due to job of the old ones. ...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.
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 moreSee 1 more doctor answer
Possibly: If you are on hemodialysis, then you will have to be at an in center facility three times a week for 3 to 4 hours per session. This form of dilaysis makes it very difficult to maintain a full time job however if you choose to perform peritoneal or home hemodialysis, they you have a better shot of maintaining a full time position. ...Read moreSee 1 more doctor answer
