Cutts MW, Thomas AN, Kishen R: Transfusion requirements during continuous veno-venous haemofiltration: the importance of filter life. Membranes with high absorptive capacity generally have a higher tendency to clot. 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 ]. CRRT provides a slow, continuous removal of fluid and metabolic wastes over a 24 hour period that mimics the physiological process of the kidneys.

Nevertheless, bleeding complications were generally reduced in the citrate groups.

The half-life is approximately 35 minutes in chronic dialysis, but longer in the critically ill. Up to now, clinical data in CRRT and availability of the drug have been limited. Among total patients at risk, the percent displayed under Filter Loss 1, 2, and 3 represents the number who lost a filter divided by the total number who entered that period at risk.

3, 4 Unfortunately, CRRT is often not "continuous," and circuit downtimes have Crit Care. Main determinants are electronegativity of membrane surface and its ability to bind plasma proteins, as well as complement activation, adhesion of platelets, and sludging of erythrocytes [30] (Figure 1). Fifty-four out of 65 patients (83%) lost at least one filter. Clogging is detected by declining sieving coefficients of larger molecules and increasing transmembrane pressures. For several reasons, continuous venovenous hemofiltration (CVVH) appears to be associated with shorter circuit life than continuous venovenous hemodialysis (CVVHD) [23]. The generation of buffer is related to the conversion of sodium citrate to citric acid: Na3 citrate + 3H2CO3 citric acid (C6H8O7) + 3NaHCO3. Predilution particularly reduces middle molecular clearance [27], the clinical consequences of which are still unclear.

Training includes the recognition and early correction of a kinked catheter and the adequate rinsing of the filter before use since blood-air contact activates coagulation [20, 21].
