title: [Protein-sparing mechanisms of parenteral feeding. I. Principles and methods].
abstract: The first part of this review deals with the response of organism to protein losses in relation to basic conditions of healthy subjects. Then it is differentiated between the consequences of substrate shortage observed in fasting metabolism and the impact of increase losses of substance occurring after trauma or operation. This distinction seems to be important not only because of the different metabolic responses of organism but also with respect to the different quantitative aspects underlying rational assessment and use of clinical treatment. In the second part an overview is given concerning the possibilities of the measurements of protein losses as well as the methodical assumptions of their valuation. At this, such methods which can be used and performed in clinical conditions are placed into the foreground. It is pronounced, that protein losses measured can only be interpreted correctly, if the clinical situation of the day as well as the time course of disease are carefully taken into consideration.
