Study summary

The study hypothesis is that with Evodial in patients requiring heparin free dialysis, the heparin free treatment can be performed easily (without saline flushes or blood predilution) and is at least not inferior and maybe superior to the standard care heparin free treatment in terms of clotting.

What researchers measure

Primary outcomes

  1. Clotting of the dialysis session

    To evaluate the rate of successful treatments, clotting in the air traps will be evaluated using a scale grading from 1 to 4 and previously described in the literature. The first heparin free dialysis treatment will be considered successful when there is: * No complete occlusion of air traps or dialyzer rendering dialysis impossible (grade 4 of the scale), * No additional saline flushes to prevent clotting, * No change of dialyzer or blood lines because of clotting * No premature stop (early rinse-back) because of clotting

    Time frame: During first dialysis session_Dialysis duration: 4 hours

Secondary outcomes

  1. Clotting during consecutive dialysis session

    As for the first heparin free dialysis treatment, treatments will be considered successful when there is : * No complete occlusion of air traps or dialyzer rendering dialysis impossible (grade 4 of the scale), * No additional saline flushes to prevent clotting, * No change of dialyzer or blood lines because of clotting * No premature stop (early rinse-back) because of clotting.

    Time frame: 2nd and 3rd consecutive dialysis sessions

  2. Follow up of clotting during the dialysis sessions

    * Grade 1: No detectable clotting * Grade 2: Minimal clot formation (Presence of fibrinous ring) * Grade 3: Clot formation (up to 5 cm) but dialysis still possible * Grade 4: complete occlusion of air traps or dialyzer rendering dialysis impossible

    Time frame: During all dialysis sessions

  3. Efficacy: Ultrafiltration

    Measurement of urea, creatinine and ionogramm, UF achieved

    Time frame: During all dialysis sessions

  4. Ease of use

    Collection of saline flushes performed (volume and time)

    Time frame: During all dialysis sessions

  5. Incidence of AEs/SAEs

    Follow-up of AEs/SAEs

    Time frame: During all dialysis sessions
