Minimum UF rate

  1. 0
    Hello all!

    When I worked for DCI, they told me that patients' goals had to be set to a minimum UF rate of 300ml/hr. They said if it wasn't the minimum, the patient would not get any clearance. This was on a reuse dialyzer. So if patient came in under dry weight, we still set the goal to 1000ml and just replaced with saline.

    When I moved to the hospital, they would set the goal to a total of only 100ml all the time if the Patient was dry. It was their policy so I went with it an couldn't find any info out there about proof one way or the other. I checked the ANNA website and couldn't find specifics.

    To me it makes sense that if you're not removing any fluid, then how does the excess potassium, calcium, and other particles leave the blood system. The particles have to be taken out along with fluid. So if you're not removing any fluid and goal is set to basically nothing, how can they be getting good dialysis?

    What does your job say?

    Docs in the hospitals are always ordering 0UF, but can't I just do fluid replacement to ensure best treatment?

    Thanks!

    If the UF is turned off, the blood continues to run countercurrently against the dialysate so there is the same clearance. The clearance, of course, is determined by the BFR and the DFR. When you are doing pure ultrafiltration, the dialysate flow is turned off and there is no clearance. In that case if you turn the UF off the blood is just spinning with nothing happening. Obviously if the UF is turned off for the whole treatment you will net an intake of whatever volume the rinseback is.
