What is Peripheral Vein Feeding

Intravenous feeding is a method of  providing parenteral nutrition when a  patient cannot take in food or formula through the gastrointestinal  tract. Various solutions of  dextrose, aminoacids, vitamins, minerals and lipids can be  fed through peripheral veins. But in this method the nutrient and kilocalorie intake is  limited. It is used only when the nutritional need is not extensive or long term, where it is  provided peripherally as a mixture of 5-10%  glucose, a 3.5-5%  amino acid solution and 10-20%  lipid emulsion. The total fat intake  should not exceed 2.5 g ,kg/day. Vitamins, minerals and electrolytes are added  as necessary, based  on  requirements  and intake. The osmolarity  of  the solution should not be greater than 600 mOsin/L, What do you understand  by  this? Well, it simply means that large amounts of solution are needed  to meet nutritional requirements. It is also used as a supplement to oral feeding in patients who cannot meet nutritional requirements completely by the oral or enteral route.
