Non- Clinical Coagulation Activation During Hemodialysis

Non- Clinical Coagulation Activation During Hemodialysis: a Cross-sectional Study Evaluating Agreement and Correlation Between Hemodialysis Session Parameters, Biological Markers and Objective Measurements of Hemodialyzers: "NC-coact"

Every patient included in the study will undergo 1 conventional hemodialysis treatment, ie 1 study visit. During the conventional hemodialysis treatment lasting 4 hours, 2 blood samples will be taken at different time points (5 minutes after dialysis start and 240 minutes after dialysis = at the end of the dialysis session) to evaluate coagulation activation (TAT, PF1+2). Hemodialysis session parameters (arterial and venous pressure, TMP, OCM, BVM and prefilter pressure) will be noted at different time points (T5, T30, T60, T120, T180, T240). After discontinuation of the dialysis session, total cell volume will be measured using the Renatron II system® and the number of open fibers will be determined using micro-CT scanning.

Inclusion Criteria:

• ≥ 18 years of age.
• Patients able and agree to provide signed informed consent.

Exclusion Criteria:

• Known allergy for polysulphone dialysis membrane.
• Use of vitamin K antagonists or novel oral anticoagulant therapy.
• Use of chronic heparin treatment, UFH or LMWH.
