Abstract
Introduction. Nowadays, nutritional support is an integral part of the management of patients in hospitals of any profile. Parenteral nutrition (PN) is a vital therapy and is indicated in those situations when enteral or oral nutrition is impossible or insufficient, for example, in such clinical conditions as advanced variants of Crohn's disease and ulcerative colitis, stenotic deformities of the esophagus, comatose change of consciousness, cancer cachexia, neuropathies of various etiologies, and others. The aim of the present study was to investigate preparations for parenteral nutrition as part of an integrated approach to the treatment of various pathologic conditions. Parenteral nutrition is in modern clinical medicine an integral part of adequate treatment in the presence of protein-energy deficiency in patients. Currently, there are many nutrient mixtures that can compensate for nutrient losses in various pathologies. There are standard systems that can compensate for substrate deficiencies individually, but the most effective are considered to be 3-in-1 systems, which are more harmonious and balanced in their composition, which, in turn, leads to the fullest satisfaction of the nutrient needs of patients. Conclusion. At the same time, it is necessary to take into account that in case of irrational use, the risks for the patient increase, therefore, in order to mitigate them, it is necessary to implement programs to control the production of mixtures and assess their qualitative and quantitative composition.
