About

The current study aims to assess the HemoControl prescription in On-Line Hemodiafiltration treatment.

Full description

Hemodiafiltration (HDF) is a dialysis technique that allows the removal of high molecular weight toxic solutes exploiting the convective transport through the dialyzer membrane: at the same time, the HDF has a positive impact on the systemic hemodynamic, ameliorating in this way the tolerance of the treatment. Unfortunately, also the HDF therapy can be not well tolerated, introducing in the patients serious hypovolemia during the removal of the body water accumulated in the interdialytic period.

The HemoControl system, automatically controlling the relative blood volume change of the patient, avoids the onset of the hypovolemia. Today the HemoControl system can be used only during conventional hemodialysis treatments; the objective of this study is to combine the advantages of the intradialytic hemodynamic stabilization achievable by means of HemoControl with the inherent advantages, both of depurative and cardiovascular kind, typical of the Hemodiafiltration technique.

---

7 participants in 2 patient groups

HD and HDF

Experimental group

Description:

During one part of the study (study phase A) patients will undergo hemodialysis (HD) treatments with Hemoscan over 2 weeks (Run-In period), followed by 12 HD sessions with HemoControl during the following 4 to 6 weeks. Separated by a one week wash out period, the same patients will be switched to On-Line Hemodiafiltration (HDF) treatments (study phase B), for a Run-In period of 2 weeks with Hemoscan, followed by 12 On-Line HDF sessions with HemoControl over the last 4 to 6 weeks of the study period.

Treatment:

Device: ARTIS hemodialysis system

HDF and HD

Experimental group

Description:

patients will be treated vice versa, starting with On-Line Hemodiafiltration (HDF) followed by hemodialysis (HD) with the same respective Run-In periods and a washout period as patients in Arm hemodialysis (HD) and Hemodiafiltration (HDF) .

Treatment:

Device: ARTIS hemodialysis system
