Clogging enhances the blockage of hollow fibers as well. Some form of anticoagulation is generally used to maintain filter patency.

This may be explained by the higher ultrafiltration rate, opening more channels and thus increasing the actual surface and the amount of protein adsorbed. Pharmacotherapy. Its mild impact on hemodynamics and solute clearance rate is preferred for critically ill patients. There was no difference between groups in percentage who lost their first filter (88% vs. 81%), or second filter (73% vs. 72%).

After the first report of Mehta and colleagues [76], a wide variety of homemade citrate systems for CRRT have been described. According to Poisseuille's law, flow through a catheter is related to the fourth power of radius and inversely related to length, indicating that a thick (13 to 14 French) and short catheter is preferable. endobj endobj Because anticoagulatory strength of the solution depends on the citrate concentration, it is best expressed as molar strength of citrate. 2001, 29: 748-752. Critically ill patients may develop a procoagulant state due to early sepsis, hyperviscosity syndromes, or antiphospholipid antibodies. Biocompatibility is significantly influenced by membrane characteristics. Flow through end holes is laminar, which is optimal, whereas flow through side holes is turbulent and even locally stagnant, contributing to early clotting.

Furthermore, high abdominal pressures or high or very negative thoracic pressures, occupancy by other catheters, patency or accessibility of veins, anatomy, posture, and mobility of the patient determine choice of the site.

These presumed abnormalities in hemostasis have been associated with filter clotting during continuous renal replacement therapy (CRRT). endobj Unfractioned heparin (UFH) is the predominant anticoagulant. 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. Due to the unreliability of PTT levels in patients with COVID-19, a COVID-specific CRRT anticoagulation protocol (referred to as protocol henceforth) which dosed systemic unfractionated heparin (UFH) by anti-factor Xa levels was piloted at one center starting April 13, 2020.

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 .
