A blood replacement base fluid and its preparation method

Abstract

A blood displacement foundation liquid comprises calcium ions and citron acid radicals. The content of each component in each liter of injection water is as follows: citron acid radicals are 5 to 15 mmol and calcium ions are 1.2 to 1.8 mmol. The blood displacement foundation liquid has good anticoagulation effects and effectively prevents the hypocalcemia effect.

Description

technical field

[0001] The invention relates to a blood replacement base fluid and a preparation method thereof. Background technique

[0002] Blood purification therapy, especially continuous blood purification therapy, is one of the main treatment measures for critically ill patients today, and is as important as mechanical ventilation and total parenteral nutrition therapy. This technology can enable patients with multiple organ failure to undergo replacement therapy for renal or non-renal diseases smoothly. Acute respiratory distress syndrome (ARDS) and acute necrotizing pancreatitis play an increasingly important role. The technology mainly includes continuous venous-venous hemofiltration (CVVH); continuous arterial-venous hemodialysis (CAVHD) and continuous venous-venous hemodialysis (CVVHD); continuous arterial-venous hemodiafiltration (CAVHDF) And continuous veno-venous hemodiafiltration (CVVHDF); slow continuous ultrafiltration (SCUF); continuous high-flow dialysi...

Embodiment 1

[0035] Embodiment 1 Preparation of blood replacement base fluid of the present invention

[0036] Take 10 moles of anhydrous glucose, 100.7 moles of sodium chloride, 0.75 moles of magnesium chloride hexahydrate, 1.4 moles of calcium chloride dihydrate, and 9 moles of sodium citrate dihydrate, dissolve them in 400 liters of water for injection, and then add activated carbon for adsorption. Filter with a 0.45 μm titanium rod, add water for injection to 1000 liters, filter through a 0.22 μm terminal filter, fill it into a PVC infusion bag with a capacity of 4000 ml, seal it, and sterilize at 115 degrees Celsius for 30 minutes to obtain the product.

[0037] In the prepared replacement base solution, the concentration of each component is shown in Table 1:

Embodiment 2

[0042] Embodiment 2 The screening of the concentration of each component in the blood replacement base fluid of the present invention

[0043] The principle of citrate anticoagulation is that citrate complexes free calcium ions in the blood at 1:1 to block the blood coagulation chain. Or the content of sodium citrate should be at least greater than the sum of the calcium content in the replacement base fluid and the amount of free calcium ions in the mixed blood during use. Application in replacement therapy, China Blood Purification, 2005, 4(1): 42], the amount of replacement base fluid is mostly 2000-4000 ml / hour, and the blood flow is mostly 120-160 ml / min. Based on this calculation, the replacement base The citrate contained in the solution should at least be able to complex and replace the calcium content in the base solution (0.225 mmol / L), and the amount of free calcium ions in the corresponding blood (the highest is: the upper limit of the concentration of free calcium...
