[Parenteral nutrition--peripheral venous feeding].
Generally, the terms peripheral-venous nutrition and hypocaloric parenteral nutrition are synonymous. Both supply the patients with roughly 2 g carbohydrates and 1.0 g-1.5 g amino acids/kg BW/day. In Germany there are so-called 'complete' or 'combination' solutions on the market, which contain these amounts of nutrients in 3-liter-concepts. For peripheral-venous application the osmolality of the solutions is important. Generally, only solutions with an osmolality of twice the concentrations of plasma will be tolerated by peripheral veins. Since osmolality is widely a function of electrolyte concentrations, solutions with a low mineral content are preferable for peripheral-venous use. The main advantage of hypocaloric parenteral nutrition is its easy handling in the early postoperative period. In clinical practice, due to the hazard of intolerance reactions to fructose and sorbit, the use of glucose or xylitol as carbohydrates in hypocaloric parenteral solutions is recommended.
