Given the long half-life of fondaparinux and danaparoid (more than 24 hours), monitoring of anti-Xa is mandatory. Fifty-seven out of 65 patients (88%) initiated CRRT for AKI, whereas 8/65 patients (12%) had end stage renal disease. 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]. Slow reaction to pump alarms contributes to stasis of flow and early filter clotting. 2000, 53: 55-60. 1993, 41: S237-S244. 2003, 18: 121-129. The use of r-hirudin is discouraged because of severe adverse events, extremely long half-life (170 to 360 hours), and the requirement of ecarin clotting time for monitoring [60]. The process is still incompletely understood, but interplay between the protein constitution of plasma, rheological characteristics of blood, capillary and transmembrane flow, membrane characteristics, and possibly the use of different resuscitation fluids influence this process [10, 27]. Critically ill patients may develop a procoagulant state due to early sepsis, hyperviscosity syndromes, or antiphospholipid antibodies. Semin Dial. Some of these processes may occur locally at the membrane. Introduction and Aims: CRRT (Continuous Renal Replacement Therapy) is a useful modality for acute kidney injury (AKI) with hemodynamic instability. PubMedGoogle Scholar. There are no randomized controlled trials showing which anticoagulant is best for HIT. Clinical review: Patency of the circuit in continuous renal replacement therapy, http://ccforum.com/articles/theme-series.asp?series=CC_Renal. Another option for reducing the filtration fraction is to administer (part of) the replacement fluid before the filter. 10.1378/chest.126.3_suppl.188S. Unauthorized use of these marks is strictly prohibited. CRRT. 10.1093/ndt/12.8.1689. This may or may not lead to platelet activation and consumption, thrombocytopenia, and both arterial and venous thrombosis. 2005, 68: 2331-2337. Its major advantages are the low costs, ease of administration, simple monitoring, and reversibility with protamine [9, 45]. Continuous renal replacement therapy (CRRT) delivers gradual clearance of solutes, fluid balance control, and haemodynamic stability. Low levels of AT decrease heparin activity and are associated with premature clotting of the circuit [3, 39, 40]. Furthermore, it might decrease the synthesis and expression of tissue factor and enhance fibrinolysis [43]. J Thromb Haemost. The interpretation of studies evaluating circuit life in CRRT, however, is hampered by the complexity and interplay of the factors mentioned. Oudemans-van Straaten HM, Wester JP, de Pont AC, Schetz MR: Anticoagulation strategies in continuous renal replacement therapy: can the choice be evidence based?. Their mean molecular weight is between 4.5 and 6 kDa, and their mean half-life ranges from 2.5 to 6 hours and is probably even longer in renal insufficiency. Res Pract Thromb Haemost. The PrisMax System is designed to give healthcare professionals more confidence in the delivery of continuous renal replacement therapy (CRRT) and therapeutic plasma exchange (TPE) therapies. If citrate accumulates, iCa decreases and metabolic acidosis ensues, since bicarbonate continues to be removed by filtration or dialysis, while citrate is not used as a buffer. 2006, 19: 133-138. Kidney Int Suppl. Both PGE1 and PGI2 have been investigated in CRRT, alone or in combination with heparins. 10.1097/00003246-200104000-00010.

Mechanism of contact activation by hemofilter membranes. Because the inner diameter counts, the material is crucial. Membranes with high absorptive capacity generally have a higher tendency to clot. 10.1159/000083938. QB = QF (Htfilter/(Htfilter - Htpatient). Diagnosis depends on a combination of clinical and laboratory results [57]. 2003, 18: 2097-2104. CRRT is a type of blood purification therapy used with patients who are experiencing AKI. Cointault O, Kamar N, Bories P, Lavayssiere L, Angles O, Rostaing L, Genestal M, Durand D: Regional citrate anticoagulation in continuous venovenous haemodiafiltration using commercial solutions. However, compared to the historical controls, mean daily serum creatinine changes were not significantly different [25]. Some form of anticoagulation is generally used to maintain filter patency.

Premature circuit clotting is a major problem in daily practice of continuous renal replacement therapy (CRRT), increasing blood loss, workload, and costs. 2020;18:1421. doi: 10.1111/jth.14830. Aim: We aimed to characterize the burden of CRRT filter clotting in patients with COVID-19 infection and to describe a CRRT anticoagulation protocol that used anti-factor Xa levels for systemic heparin dosing. These presumed abnormalities in hemostasis have been associated with filter clotting during continuous renal replacement therapy (CRRT). Continual rebuilding of the circuit is a drain on resources, both nursing staff and financial. Ultrasound-guided catheter placement significantly reduces complications [17]. 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. Ramesh Prasad GV, Palevsky PM, Burr R, Lesko JM, Gupta B, Greenberg A: Factors affecting system clotting in continuous renal replacement therapy: results of a randomized, controlled trial. Severe clotting was defined as >2 filter losses in 48 hours or one filter loss <8 hours into CRRT.

Biocompatibility is significantly influenced by membrane characteristics. Kidney Int. It may be questioned whether the benefits of citrate (less bleeding, possibly a longer circuit survival, and less bio-incompatibility [9698]) weigh against the greater risk of metabolic derangement and possible long-term side effects like increased bone resorption [99]. 8 0 obj Isla A, Gascn AR, Maynar J, Arzuaga A, Corral E, Martn A, Solins MA, Muoz JL: In vitro and in vivo evaluation of enoxa-parin removal by continuous renal replacement therapies with acrylonitrile and polysulfone membranes.

For optimal anticoagulation, citrate flow is adjusted to blood flow, targeting at a concentration of 3 to 5 mmol/l in the filter [71]. 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. Randomized studies in critically ill patients on CRRT which evaluate the effect of catheter site or design on circuit flow and survival are not available. Kidney Int. Differences in circuit life between studies can be explained in part by the wide variety of citrate dose (2 to 6 mmol/l blood flow), fixed citrate infusion or citrate dose titrated on postfilter iCa, the use of dialysis or filtration (predilution or postdilution), differences in CRRT dose and filtration fraction, or by a reduction in citrate flow used for control of metabolic alkalosis.

Systemic anticoagulation interferes with plasmatic coagulation, platelet activation, or both and should be kept at a low dose to mitigate bleeding complications. These presumed abnormalities in hemostasis have been associated with filter clotting during continuous renal replacement therapy (CRRT). Citrate replacement solutions for predilution CVVH contain 11 to 15 mmol citrate per liter [8388] and for predilution CVVHDF, 13 to 23 mmol/l [40, 8992]. de Pont AC, Oudemans-van Straaten HM, Roozendaal KJ, Zandstra DF: Nadroparin versus dalteparin anticoagulation in high-volume, continuous venovenous hemofiltration: a double-blind, randomized, crossover study. 10.1016/j.clinthera.2005.09.008. 1997, 12: 1689-1691. -, Zhou F, Yu T, Du R, et al. None of the proposed systems can attain perfect acid-base control using one standard citrate, replacement, or dialysis solution. Filter size may play a role and larger surfaces may be of relevance for filter survival and solute clearance when CVVHD is applied. These risks can be mitigated via administration of systemic anticoagulation [ 14 ]. 10.1038/ki.1990.300. Ward DM, Mehta RL: Extracorporeal management of acute renal failure patients at high risk of bleeding. Apart from bleeding, major side effects of UFH include development of heparin-induced thrombocytopenia (HIT), hypoaldosteronism, effects on serum lipids, and AT dependency [47]. The use of regional anticoagulation with citrate is limited by the patient's capacity to metabolize citrate, which is decreased if liver function or tissue perfusion fails [74]. Because the citrate patients often had a higher risk of bleeding, groups are generally not comparable. Up to now, large randomized controlled trials evaluating the influence of the type of membrane on circuit life during CRRT have been missing. Most information comes from observational and in vitro studies in chronic hemodialysis patients, who need their catheters intermittently and for a much longer time (reviewed in [11]).
