The aim of the study is to evaluate the efficacy of the SOLACEA-H dialyser, particularly in patients at high risk of haemorrhage, during post-dilution haemodiafiltration sessions with complete or partial heparin sparing. It will be compared with another dialyser (HYDROLINK-NVU)

This is a randomised, crossover, open-label, prospective, multicentre post-marketing clinical follow-up study comparing two medical devices used (SOLACEA-H dialyser vs HYDROLINK-NVU dialyser) for their intended purpose.

Each patient will be followed for approximately 2 months, depending on the number of sessions in the anticoagulant reduction phase.

Patients will be offered the study by the investigator during a dialysis session as part of routine practice. If the patient accepts and signs the informed consent form, he or she will receive a succession of dialysis sessions including first the SOLACEA-H then the HYDROLINK-NVU membrane, or vice versa, depending on randomisation.
