Type of fluid used in Home-Dialysis?

[kristina]

My question is this:

In PD-home-dialysis, the liquid that “runs through” to extract “waste products”,
is it, everywhere, a glucose-based liquid or are there other types of liquid
that perform the same task?

Why glucose-based?

Furthermore, in NX-stage, is the sterile fluid also glucose-based?

Thank you, Kristina.

There are two types of dialysate used to remove excess fluid in PD.  One is dianeal, which contains dextrose.  It is the dextrose that removes the excess fluid.  Dianeal has a 6 hour dwell, and should be replaced at least every 6 hours.  The other is extraneal, which is starch based, and has a 12-15 hour dwell, thus eliminating a midday exchange.

Thank you for the information, peleroja.

I was wondering about the dextrose/glucose-based fluid,
because I have read it is the best medium being found
to act as the agent in the process to extract “waste-products”.

As regards “starch”, my immediate thought is that pre-Dialysis patients
and patients on Dialysis usually have to reduce their intake of starch foods.
I can appreciate that the fluid used may be some modified starch but
I wonder if this starch-based-fluid is less kind to the body
than the glucose-dextrose-based fluid?

Thanks again from Kristina.

Correction Peleroja , in the UK there are 3 types, Dianeal and Extraneal as you stated there is also Physioneal which is glucose based. I myself couldnt tolerate Dianeal it gave me the most terrible stomach ache. However i managed to achieve 6 yrs + on Physioneal. It is also recommended over here that exchanges are four hourly (after that there is a strong possibility of re-absorption, depending on if you are a high or low transporter) Extraneal is usually only used over here for overnight dwells or if on APD a long daytime dwell. I was told it is more efficient at pulling fluid off but not as efficient at pulling toxins off , hence a combination of the two is usually used.

Thank you so much for going into this in greater detail.

I now appreciate the complex issue of Dialysis.
I didn’t realize how complicated the Dialysis-process was,
in particular, the fact it is a two-way-issue (yes, a double-edged sword)
and therefore a balancing-act between extracting the waste-material
and absorbtion of ingredients from the Dialyte.

This really is a complicated matter and I am so pleased you took the trouble to explain it.

I hadn’t appreciated the difference between the Urea and Creatinine in the process
of being extracted from the blood.

Thanks again from Kristina.
