The patient is classified as well-nourished, somewhat malnourished or seriously malnourished on the basis of information about weight development, food intake, symptoms and physical functioning. This classification has been shown to correlate well with more objective measurements of nutritional status and morbidity, mortality and quality of life.
Actions include individual adjustment of diet according to symptoms and nutritional status.
The end of the tube is often inserted into the stomach. In the event of poor gastric function, total gastrectomy or pancreatic resection, the feeding tube should be inserted in the duodenum or jejunum. The position of the feeding tube is vital for the choice of feeding-tube solution and mode of administration.
The most common solution is to insert the tube nasogastrically, but it can also be done through the abdominal wall (PEG).
It is preferable to use intravenous or parenteral nutrition as a supplement to oral/tube feeding instead of only TPN (total parenteral nutrition).
Central veins must be used for TPN with high osmolality.
Peripheral veins can be used for short-term parenteral nutrition. In this case, a large vein on the forearm is used and a small needle. Nutrition is then given as more diluted solutions.
