Replenishment of the need for protein with parenteral nutrition. Method for calculating the volume of solutions of crystalline amino acids and protein hydrolysates

One of the most important tasks of parenteral nutrition (PN) is the replenishment of the body's protein requirements. Currently, there is no doubt that this problem can be solved by intravenous administration of crystalline amino acids (PKA) and protein hydrolysates (GB). This means that coarsely dispersed proteins (plasma, albumin, protein) are not suitable for PP, since after administration for a long time (2-4 weeks and more) circulate in the blood without significant changes and only then undergo hydrolysis with subsequent assimilation in the form of amino acids (A K) and the simplest peptides. Thus, the use of coarse protein preparations in PN pursues specific goals within the framework of general infusion therapy, and the protein contained in them does not count towards plastic needs.
