Grundlagen der klinischen Ernährungstherapie und die Anwendung von Aminosäurenlösungen

Abstract

The high value of clinical nutrition as an important component in polypragmatic therapy of severely ill patients with increasing age and restricted compensatory capacity is today unquestioned. The areas of interest and applications have reached a high degree of complexity by many differentiations. The metabolic interrelations under pathological conditions influence especially the application of amino acids. By the enormously increased standards of analytical procedures and instruments huge amounts of data have been gathered but methods and tools for interpreting the complex analytical results have not been developed to the same degree. Considering physiological, pathological biochemical, and biophysical alterations, this review discusses application of amino acids, evaluation and interpretation procedures, as well as indications, contraindications, and effective monitoring. The important regulatory function of the liver in connection with the urea production rate, and the physiological pattern and concentrations of amino acids in plasma are both discussed in detail. Also discussed is the therapeutic advantage of determining total concentration and relative composition of the amino acid pool in plasma, especially in severely ill patients.
