These risks can be mitigated via administration of systemic anticoagulation [ 14 ]. Intensive Care Med. Primary outcome was time to CRRT filter loss. During this therapy, a patient's blood passes through a special filter that removes fluid and uremic toxins, returning clean blood to the body. Citrate is partially removed by convection or diffusion and partially enters the systemic circulation, where iCa rises again due to the dilution of extracorporeal blood, the liberation of chelated calcium when citrate is metabolized, and the replacement of calcium. For optimal anticoagulation, citrate flow is adjusted to blood flow, targeting at a concentration of 3 to 5 mmol/l in the filter [71]. During continuous renal replacement therapy (CRRT), blood is conducted through an extracorporeal circuit, activating coagulation by a complex interplay of patient and circuit. 10.1016/j.jcrc.2006.02.002.

The most common anticoagulant options for continuous renal replacement therapy (CRRT) include unfractionated heparin (UFH), regional citrate anticoagulation (RCA), and no anticoagulation. Given these limitations, a possible scheme for UFH consists of a bolus of 30 IU/kg followed by an initial rate of 5 to 10 IU/kg per hour in patients with normal coagulation.

Results: Sixty-five patients were analyzed, with 17 using the anti-factor Xa protocol to guide systemic heparin dosing whereas 48 were treated with standard of care anticoagulation dosed by PTT . Slow reaction to pump alarms contributes to stasis of flow and early filter clotting. These measures include optimization of the catheter (inner diameter, pattern of flow, and position), the settings of CRRT (partial predilution and individualized control of filtration fraction), and the training of nurses. Its main disadvantage is clotting of the extracorporeal circuit, leading to decreased solute clearance and inadequate metabolic . Clogging is due to the deposition of proteins and red cells on the membrane and leads to decreased membrane permeability.

However, accumulation of citrate due to decreased metabolism can be detected accurately by the symptoms of metabolic acidosis, increasing anion gap, ionized hypocalcemia, and most specifically by an increased total/iCa concentration. Inhibition of platelet activation can be obtained by the use of prostaglandins (PGs) (summarized in [9, 59]). In a recent retrospective case control study in patients with septic shock undergoing CRRT with heparin, supplementation of AT to keep plasma concentration above 70% increased circuit survival time [42]. The half-life is approximately 35 minutes in chronic dialysis, but longer in the critically ill.
