Re: when dialysis doesn't work
Sorry, but I'm not sure what you mean. You also need to specify what type of dialysis you are on. It is possible that peritoneal dialysis will cease to work properly as the peritoneal membrane changes it's capacity. This will be determined through routine labs and then subsequent specific tests. As for hemodialysis, this is the one form of dialysis they can pretty much usually make work no matter what. Are you the one on dialysis or are you asking questions for a friend? Hope you don't mind my asking.
Every form of dialysis requires a "prescription". By that I mean that certain amounts of fluids need to be taken off, it needs to be done at certain speeds, over certain time periods, and other issues. It may take some time for the doctor to determine the specific amounts of dialysis required. In addition to that, the patient needs to properly follow nutritional guidelines and restrictions as well as fluid restrictions. All the dialysis in the world won't help if you are not eating/drinking the right amounts and eating the wrong stuff.
Hope this helps a bit.
