I am writing a one or two page informative article on sodium variation. I would appreciate any feedback I can get on the topic of using sodium variation, benefits and downsides, experience noted, etc.Thank You!

Hello, Robert:I am a strong advocate on the use of sodium variation for hemodialysis. I have found that a linear approach to sodium variation can be useful in treating muscle cramps and aiding in removal of fluid. Newer machines allow for programing of both the sodium modeling as well as ultrafiltration, an added bonus for care of the patient. Variable sodium basically allows for a rapid change of the dialysis solution sodium levels usually by changing the proportioning pump internally. Generally, the proportion of concentrate to water is altered to increase the sodium level appropriately. The variable sodium option allows for a more individualized approach to dialysis for patients. Please let me know if you have further questions. I am sure that many readers have excellent experiences with sodium variation, and we would love to hear the stories!! Best wishes, and good luck with your article,
Carol

My doctor tried me on this. He told me I might get thirsty afterwards. I seemed to have a good treatment that day, but the thrist afterwards was terrible. I could not get rid of the thirst for about two days. I asked to get off of sodium modeling.

Kendra:Depending on the machine type that you use, the option of programming the sodium variation may be one that would work for you. During the last 30 minutes of treatment, the sodium level is returned to 'normal', and that helps eliminate the thirstiness that you may feel. If the sodium variation helped with your treatments, and if the treatments have gone back to being uncomfortable, you might want to see if the machines your clinic uses has the ability to program for a return to baseline during the end of treatment. Best wishes,
Carol

Hello, All:An article was released by the American Society of Nephrology on the benefits of sodium modeling and ultrafiltration profiling. There is a link in the current news section on the renal web home page. I found this article to be very informative, and thought you may also like it. Carol

There is an excellent link to an article on prevention of hypotension and the use of sodium modeling. Go the news section on the RenalWEB home page, and link from there. The blurb is entitled 'Prevention of Hypotension During Dialysis'.This is the link: http://www.blackwell-synergy.com/Journals/content/abstracts/kid/2001/59/3/abstract_kid604.asp?journal=kid&issueid=4947&artid=95930&cid=kid.2001.1&ftype=abstracts
Enjoy!

Carol,
Can you sum the article up? Since there are so many possible settings for sodium modeling were they saying that the particular setting they chose was a possible starting point? What was their point in saying that the arterial pressures were lower with UF? The article didn't say what percentage of patients were still affected by low bp, if the setting of their dry weights had anything to do with how stable their bps were. Previously I had bp drops as my dry weight was always set too low. Simply keeping it raised high enough has helped me and I am not on sodium modeling. I went on sodium once for one tx. I don't know if they forgot to bring it back down to 140 the last half hour. The tx went well, but I had terrible thirst for two days aferwards. Does anyone know do some patients still experience thirst with it even if it is set for 140 at the end? I am thinking of trying it again.

Casey:You shouldn't be that thirsty at the end of treatment if your sodium modeling is appropriate. I would recommend trying it again to help with your blood pressure control. This article discussed a study performed on a small sample of patients on hemodialysis. Best results were seen in controlling dialysis hypotension with sodium modeling (used in a linear method of increase to 152 mEq/L, decreasing to 140 mEq/L at the end of treatment). Other studies have shown similiar results. I hope this helps.
