[Problems with hyperalimentation in intensive care units (author's transl)].

The application of parenteral nutrition in patients in intensive care units can be limited by shock, septicemia and metabolic disorders. Stress- or trauma-induced glucose intolerance sometimes makes it difficult to maintain the caloric requirements with glucose. Sugar substitutes seem to be of advantage in these cases. Meticulous care is essential to avoid severe complications arising from the use of the central venous feeding catheters.
