In early sepsis, activation of the coagulation system is triggered by proinflammatory cytokines that enhance the expression of tissue factor on activated mononuclear and endothelial cells and simultaneously downregulate natural anticoagulants, thus initiating thrombin generation, subsequent activation of platelets, and inhibition of fibrinolysis [1]. In chronic dialysis patients, best flows are obtained with the tip in the right atrium [12, 13].

Continuous renal replacement therapy (CRRT) is the favoured modality of renal replacement therapy for haemodynamically unstable patients with acute kidney injury (AKI) in the intensive care unit (ICU). Its mild impact on hemodynamics and solute clearance rate is preferred for critically ill patients. 2004, 97: c131-c136. Circuit patency can be increased. 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.

Filter size may play a role and larger surfaces may be of relevance for filter survival and solute clearance when CVVHD is applied. Nevertheless, bleeding complications were generally reduced in the citrate groups. Introduction and Aims: CRRT (Continuous Renal Replacement Therapy) is a useful modality for acute kidney injury (AKI) with hemodynamic instability. Traditionally, this is prevented by using regional citrate anticoagulation (RCA) or prefilter unfractionated heparin.

Up to now, clinical data in CRRT and availability of the drug have been limited. Given a recent review on anticoagulation strategies in CRRT [9], this overview also incorporates the role of non-anticoagulant measures for circuit survival.

Its major advantages are the low costs, ease of administration, simple monitoring, and reversibility with protamine [9, 45]. However, thrombin activation has been observed even without detectable systemic activation of these systems [3, 4]. 10.1093/ndt/gfg272. Continuous venovenous hemodiafiltration (CVVHDF) combines the possible advantages of hemofiltration (higher middle molecular clearance) with less hemo-concentration. Another option for reducing the filtration fraction is to administer (part of) the replacement fluid before the filter. However, the level of anticoagulation should be individualized.

CRRT does not appear to increase survival compared to intermittent renal replacement therapy (IRRT), but may affect renal recovery [ 1, 2 ]. Spronk PE, Steenbergen H, ten Kleij M, Rommes JH: Re: Regional citrate anticoagulation does not prolong filter survival during CVVH. The most common anticoagulant options for continuous renal replacement therapy (CRRT) include unfractionated heparin (UFH), regional citrate anticoagulation (RCA), and no anticoagulation. If citrate is used for anticoagulation of the circuit, separate thromboprophylaxis must be applied. In daily clinical practice, citrate measurement is hampered by the limited stability of the reagents. 1990, 38: 976-981.

Clogging during CRRT worsens resistance toblood flow through filter and thus leads toincrease infilter pressure drop.

Given the long half-life of fondaparinux and danaparoid (more than 24 hours), monitoring of anti-Xa is mandatory.
