Within clinical nutrition practice, a distinction is made between two primary categories of therapeutic preparations: those administered enterally—directly into the gastrointestinal tract—and those delivered parenterally, bypassing the digestive system entirely. The available range of these products is highly diversified, tailored to address the specific demands arising from various pathological conditions as well as the functional capacity of the patient’s alimentary tract. Their composition and formulation are meticulously designed to provide optimal metabolic and nutritional support, contingent upon the clinical status and therapeutic requirements of the individual.
Nutritional treatment preparations
Food preparations are produced in liquid form or in powder form. All industrial diets contained in the relevant products are balanced and the ingredients selected to make them as bioavailable as possible, from which the body can easily derive the necessary energy and nutrients. These products have a low osmolarity (about 400 mOsmol/L).
It's an intravenous nutritional treatment
If this is possible and if the functioning of the digestive tract allows it, it is advisable that the intravenous diets contain protein which does not require digestion, as they should be the most similar form of natural food. In this way treatment can be distinguished by the content of nutrients. These are polymers and monomers. Monomers are elementary diets. They are characterized by protein content that does not need digestion because they are in the form of amino acids, dupepids or tripepods.
External nutritional treatment
All-in-one food preparations are prepared in special blenders. There is also a nutrient mixture that includes amino acid solutions, carbohydrate solutions, fat emulsions, vitamins, electrolytes, and trace elements. These are the so-called All In One mixing bags (i.e. all the nutrients are in one bag). There are also preparations that have separate two- or three-chambers of protein, single-channel or single-checkered protein.
