Determination of Citrate Clearance Used in Regional Anticoagulation of Continuous Venous Hemofiltration Circuits

Determination of Citrate Clearance Used in Regional Anticoagulation of Continuous Venous Hemofiltration Circuits

Citrate anticoagulation is becoming the gold standard in dialysis in intensive care units. It is now accepted that citrate prolongs the life of filters with a lower risk of bleeding.

However, the management of citrate is complex. Optimization is based on citrate flow, blood flow and the amount of calcium reinjected. Frequently the citrate level is sub-dosed.Currently, the fraction of excretion of citrate by the hemodialysis machine is unknown. Knowing this information would allow, if it is important enough, to add an additional parameter of citrate management by adapting the level of dialysis.

The determination of citrate in an extracorporeal circulation circuit has already been performed and has been validated in the literature. We propose to perform the assay on subjects with the same starting parameters, in order to deduce the clearance of citrate.
