Clogging is detected by declining sieving coefficients of larger molecules and increasing transmembrane pressures. 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.

CRRT is a much slower type of dialysis than regular HD, as it pulls fluid or cleans the blood continuously, 24 hours a day, rather than over a 2-4 hr treatment.

Significant improvement of circuit survival, however, could be achieved only when PGs were combined with low-dose UFH or LMWH [6870]. Given the long half-life of fondaparinux and danaparoid (more than 24 hours), monitoring of anti-Xa is mandatory.

Background: Coronavirus disease 2019 (COVID-19) appears to be associated with increased arterial and venous thromboembolic disease. To minimize the procoagulant effects of hemoconcentration, it is recommended to keep the filtration fraction (the ratio of ultrafiltrate flow [QF] to blood flow [QB]) as low as possible; a value below 25% is generally recommended in postdilution mode.

This may be explained by the higher ultrafiltration rate, opening more channels and thus increasing the actual surface and the amount of protein adsorbed. Clogging, Clotting & Circuit Changes Most circuit changes are related to membrane clogging and clotting. Systemic anticoagulation interferes with plasmatic coagulation, platelet activation, or both and should be kept at a low dose to mitigate bleeding complications. 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 ]. In a non-randomized controlled study, polyamide exhibited later clotting than acrylonitrile (AN69) [31]. ASAIO J. Another important determinant of catheter flow is the patient's circulation.
