[0002] Continuous renal replacement therapy (CRRT) is a general term for all continuous and slow treatment methods for removing water and solutes, and plays an important role in the treatment of critically ill patients. In recent years, its application value in multiple injuries, severe burns and other diseases has also received widespread attention. In CRRT treatment, replacement fluid is needed, which completes the treatment purpose with blood in the filter through diffusion and convection.
[0003] The replacement fluid currently used includes finished replacement fluid, online replacement fluid produced by hemodialysis filtration machine, and manually prepared replacement fluid. Among them, the commercial finished replacement fluid is widely used because of its stable and accurate composition, reduced contamination risk, improved treatment efficiency, and convenient storage and transportation.
[0004] During the CRRT treatment process, all patients need to choose appropriate replacement fluid K + concentration according to the disease condition. The preferred CRRT anticoagulation method recommended by the guidelines is citrate anticoagulation. Citrate is a highly efficient calcium ion chelator that binds with calcium ions in extracorporeal blood circulation to reduce the concentration of calcium ions in the blood to achieve the anticoagulation effect. The recommended replacement fluid Ca 2+ concentration has no uniform standard, but when the citrate anticoagulation effect is unstable, there is no Ca 2+ replacement fluid. The use of replacement fluid can make the CRRT treatment more stable.
[0005] The existing CRRT finished replacement fluid has a single formula, and the added Ca 2+ cannot be removed, which cannot meet the specific needs of all patients, and most CRRT finished replacement fluids still need to manually configure the liquid to adjust the formula, which is inconvenient to use.
