Coupling Between Clotting Characteristics in Chronic Hemodialysis Patients and the Hemodialyzer Patency

Twenty stable chronic hemodialysis patients are included and will undergo one, two, three or four midweek test dialysis sessions, depending on a flow chart to follow. All patients are started (week 1) with an anticoagulant Clexane 50IE/kg and are dialyzed with their regular dialyzer and dialysis machine. Depending on the results of measured clotting characteristics and of the dialyzer scanning (i.e. percentage open fibers), it is decided (via the flow chart) whether the patient gets a second session (and so on) with an adapted anticoagulation therapy to ameliorate fiber patency while limiting bleedings.
