Another important determinant of catheter flow is the patient's circulation. Anticoagulation with citrate has complex metabolic consequences, which are related to the dual effects of citrate as an anticoagulant and a buffer. Both derangements are preventable by adherence to the protocol or are detectable early by strict monitoring.

The commonest form of Clotting of the CRRT filter is a major limitation to care, as it leads to inefficient dialysis, causes blood loss, and depletes limited resources (CRRT filters) [ 12, 13 ]. One small randomized cross-over study (n = 15) and one study comparing 33 patients on predilution CVVH to 15 historical postdilution controls found longer circuit survival with predilution [25, 26] at the cost of a diminished clearance [26].

In a non-randomized controlled study, polyamide exhibited later clotting than acrylonitrile (AN69) [31]. During continuous renal replacement therapy (CRRT), blood is conducted through an extracorporeal circuit, activating coagulation by a complex interplay of patient and circuit. With the evolution of standardized replacement fluids, newer machines, and high flux membranes, continuous renal replacement therapy (CRRT) has made remarkable progress in the field of extracorporeal therapies. 1 ). 2020 doi: 10.1016/S0140-6736(20)30566-3.

Kidney Int Suppl. 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. 10.1007/s001340050288.

Time from first to second filter loss (where protocol patients were exposed to low systemic UFH dosing) and time from second to third filter loss (where protocol patients were exposed to high systemic UFH dosing) were analyzed with a log-rank test. Low levels of AT decrease heparin activity and are associated with premature clotting of the circuit [3, 39, 40]. Chest. 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.

In predilution CRRT, substitution fluids are administered before the filter, thus diluting the blood in the filter, decreasing hemoconcentration, and improving rheological conditions. The generation of buffer is related to the conversion of sodium citrate to citric acid: Na3 citrate + 3H2CO3 citric acid (C6H8O7) + 3NaHCO3.
