What Are the 3 Types of Intravenous Feeding?

Intravenous feeding is used when the digestive tract cannot adequately absorb nutrients, as occurs in severe malabsorption disorders. It is also used when the digestive tract must be temporarily kept free of food, as is needed during certain stages of ulcerative colitis. It may provide all of a person's nutritional requirements.

Parenteral nutrition requires a large intravenous tube. The tube (called a central venous catheter) must be inserted into a large vein, such as the subclavian vein, which is located under the collarbone. Parenteral nutrition may be used at home or in the hospital.

A central vein administers central parenteral nutrition, most often the superior vena cava, which is positioned behind your collarbone and connects directly to your heart. Because of the bigger central vein, a larger catheter may give higher concentrations of nourishment with more calories. As a result, CPN is utilized to give whole parenteral nourishment, which is administered by the limb or neck.

Total parenteral nutrition is total nourishment for the body that is given to patients intravenously. It is administered when a person is completely unable to obtain the necessary nutrients or is unable to eat. This may be necessary if certain disorders impede your digestive tract's capacity to process food and absorb nutrients.

Peripheral parenteral nutrition is administered via a smaller peripheral vein, which may be located in your neck or one of your limbs. PPN is used to administer temporary partial parenteral feeding by utilizing faster and simpler access to the peripheral vein. For a variety of reasons, this is the most often utilized intravenous feeding treatment.
