Systemic anticoagulation inhibits plasmatic coagulation, platelet function, or both. Non-anticoagulation measures include optimization of vascular access (inner diameter, pattern of flow, and position), CRRT settings (partial predilution and individualized control of filtration fraction), and the training of nurses. The PrisMax system is designed to provide individualized therapies for critically ill patients in the intensive care unit (ICU). Kidney Int.

In predilution CRRT, substitution fluids are administered before the filter, thus diluting the blood in the filter, decreasing hemoconcentration, and improving rheological conditions. 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].

There was no difference in first or second filter loss between the anti-Xa protocol and standard of care anticoagulation groups, however fewer patients lost their third filter in the protocolized group (55% vs. 93%) resulting in a longer median third filter survival time (24 [15.1, 54.2] vs. 17.3 [9.5, 35.1] h, p = 0.04). endstream The strength of citrate solutions is generally expressed as a percentage (grams of trisodium citrate per 100 ml).

Crit Care Med. 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. Increased clotting of CRRT hemofilter leads to reduced time on CRRT and blood loss, worsening the anemia of critical illness and increasing need for blood transfusion.7,8 However, it is unknown if COVID-19 patients with AKI requiring CRRT have increased clotting of CRRT hemofilter compared to patients with septic shock with AKI requiring . 2007, 57: 189-197.

Although these processes are to some degree inevitable, they are facilitated by poor therapy management. 10.1007/s001340100907. Citrate removal by CRRT mainly depends on CRRT dose and not on modality. 1 ). Low molecular weight heparins (LMWHs) exhibit several advantages, including lower incidence of HIT [48], lower AT affinity, less platelet and polymorphonuclear cell activation, less inactivation by platelet factor-4 (PF-4), higher and more constant bioavailability, and lack of metabolic side effects [47, 49, 50].

It has been suggested that with predilution, membrane performance is better maintained by reducing protein adsorption. It is intended to be applied for 24 hours or longer through continuous, slower dialysis. During this therapy, a patient's blood passes through a special filter that removes fluid and uremic toxins, returning clean blood to the body. Its mild impact on hemodynamics and solute clearance rate is preferred for critically ill patients.

Other reasons for premature clotting related to the CRRT technique are repeated stasis of blood flow [5], hemoconcentration, turbulent blood flow, and blood-air contact in air-detection chambers [6]. In addition, anticoagulation is generally required. Htfilter and the minimal QB required for the prescribed QF can be calculated at bedside. For a constant buffer delivery, these flows are to be kept constant, while they can be adjusted to correct metabolic acidosis or alkalosis. <> Medical Intensive Care Unit, Division of General Internal Medicine, Department of Internal Medicine, Medical University Innsbruck, Anichstr. 2023 Jan;19(1):38-52. doi: 10.1038/s41581-022-00642-4.
