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.
