How TPN and Tube Feeding are Different There are two primary methods that caregivers use to deliver nutrients to patients who are partially or totally unable to digest food. The first is enteral feeding which involves delivering food directly through a catheter or tube directly into the gastrointestinal (GI) system.
What is TPN and how is it administered?
Total parenteral nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract. Fluids are given into a vein to provide most of the nutrients the body needs. The method is used when a person cannot or should not receive feedings or fluids by mouth.

Why is TPN better than enteral feeding?
In general, enteral nutrition is preferred to parenteral nutrition as it is more physiological, simpler, cheaper and less complicated. However even nasogastric feeding needs care and the more complex types of enteral nutrition such as gastrostomy and jejunostomy need significant interventions.

Enteral tube nutrition is indicated for patients who have a functioning gastrointestinal (GI) tract but cannot ingest enough nutrients orally because they are unable or unwilling to take oral feedings. (See also Overview of Nutritional Support.
Is a PEG tube enteral or parenteral?
Percutaneous endoscopic gastrostomy (PEG) tubes serve as the favorable route of feeding and nutritional support in patients with a functional gastrointestinal (GI) system who require long-term enteral nutrition, usually beyond 4 weeks.
What is meant by enteral?
Enteral is a medical term that means within, by way of, or related to the intestines. A much more common word for this is intestinal. A close synonym is enteric. In medicine, enteral nutrition involves introducing nutrients through a tube into the stomach or small intestine.

What is the difference between enteral and parenteral routes?
Enteral nutrition is administered through a feeding tube placed into the stomach or intestines. Parenteral nutrition is administered through a traditional intravenous (IV) line or via a central IV surgically placed during an outpatient procedure.
Is TPN given through a PICC line?
TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve.
What is an enteral formula?
Enteral formulas are liquid food products that are specially formulated and designed to increase the amount of various food elements and nutrients that will maintain proper physiological function of the body process. They may also be used to correct an existing deficiency.
How TPN and Tube Feeding are Different
There are two primary methods that caregivers use to deliver nutrients to patients who are partially or totally unable to digest food. The first is enteral feeding which involves delivering food directly through a catheter or tube directly into the gastrointestinal (GI) system.
What is Tube Feeding?
Enteral feeding is also called tube feeding. The food is delivered in a liquid form through the tube, which can be inserted through the mouth, nose, or directly into the small intestine.
Types of Parenteral Nutrition
Parenteral nutrition is divided into two main types: total parenteral nutrition (TPN) and peripheral parenteral nutrition (PPN).
Meeting the Nutritional Care Needs of Children through TPN or Tube Feeding
Newborns and young children dealing with a wide range of conditions, illnesses, and congenital birth defects may require either tube feeding or TPN to meet nutritional requirements. As with all patients, tube feeding is usually the preferred method if possible due to the lower risks and ease of delivery.

What is the Difference Between TPN and Tube Feeding?
TPN is the supply of all nutrients intravenously, while tube feeding is the supply of nutrients into the stomach via a tube. So, this is the key difference between TPN and tube feeding. Moreover, TPN does not rely on the GI tract functioning, while tube feeding depends on the functioning of the GI tract. Furthermore, TPN is more expensive and shows more complications, while tube feeding is cheaper and shows fewer complications. Thus, this is another major difference between TPN and tube feeding.
What is TPN feeding?
Total parenteral feeding (TPN) is one of the two types of parenteral feeding in which all daily nutrients are supplied through a large vein. Enteral feeding or tube feeding is done when a person is not in a condition to eat a regular diet through his mouth, but his GI tract functions normally. In this method, the supply ...
What is TPN?
Total parenteral nutrition is one of the two types of parenteral nutrition which is done intravenously. In TPN, complete nutrition is given to your body through a vein. Thus, the nutrients are directly pumped into the bloodstream. In TPN, the health care provider places a catheter in a larger vein. After checking the nutrient bag (TPN solution), it should be connected to the intravenous catheter. The process takes 10 to 12 hours to complete. TPN becomes a good option when a person does not have a functional GI tract or when he suffers from disorders requiring complete bowel rest. Therefore, TPN does not rely on gastrointestinal function.
How do you feed a person?
When a person is at risk of malnutrition, or has trouble in getting daily nutritional requirements, there are two methods of supplying nutrients: enteral feeding and parenteral feeding. Parenteral feeding is a way of supplying nutrients directly into the bloodstream through a vein. Total parenteral feeding (TPN) is one of the two types of parenteral feeding in which all daily nutrients are supplied through a large vein. Enteral feeding or tube feeding is done when a person is not in a condition to eat a regular diet through his mouth, but his GI tract functions normally. In this method, the supply of nutrients takes place directly into the stomach or small intestine via a tube.

Is TPN more expensive than catheter?
However, it shows a greater risk of catheter infections . TPN is also associated with blood clot developments, liver diseases and bone diseases. Moreover, TPN is more expensive and causes more complications.
Is tube feeding cheaper than TPN?
It is a simpler and cheaper method than TPN. Moreover, it shows fewer complications and infections than TPN. The nutrients go through the GI tract in the same way when we ingest foods. In order to carry out tube feeding, the person must possess a functional GI tract.
Why do we need enteral feeding?
Enteral and parenteral feeding methods are used mainly to deliver nutrients to patients who cannot digest food normally or who have non-functioning gastrointestinal tracts (GI Tracts). The nutrients are supplied in the form of liquid and can insert drugs as well as food. In some chronic cases, the patients need to be fed at night, in order to have a normal life during day time. However, these feeding operations are widely varied depending on the patient’s situation and needs.
What are the advantages of parenteral feeding?
Providing of nutrients when less than two or three small intestine present, allowing nutrition support when GI intolerance prevents oral or enteral support are the two main advantages of parenteral feeding.
Where is parenteral feeding inserted?
Normally the catheters are inserted either into patient’s jugular vein, the subclavian vein, below the clavicle, or one of the arm’s large blood vessel.
