WHAT IS ARTIFICIAL NUTRITION?

When the digestive system is unable to absorb essential nutrients, customized nutrition is an option.
There are three types of nutrition:

  • oral supplementation
  • enteral nutrition
  • parenteral nutrition

Oral supplementation is administered by mouth, unlike enteral and parenteral nutrition, which have different routes of administration.

ORAL SUPPLEMENTATION

When is oral supplementation prescribed?

Oral supplementation is prescribed when a person can no longer eat properly, or when their normal diet is insufficient to cover their energy needs. This is the first step in renutrition.

The treatment

Oral supplementation refers to food products that are taken as a complement to the diet, not as a replacement, and whose composition is adapted to meet the patient’s specific needs.
Complements therefore have different characteristics:

  • Enriched with calories, proteins, vitamins and/or minerals;
  • Different textures ;
  • Varied tastes.

The prescription

Oral supplements are prescribed by a doctor when the digestive tract is functional and the patient has sufficient swallowing capacity.

ENTERAL NUTRITION

When is enteral nutrition prescribed?

When oral feeding is difficult or impossible, or when nutritional intake is inadequate, enteral feeding is recommended. It will help preserve digestive activity and combat malnutrition and dehydration. This artificial nutrition technique uses a tube connected to the stomach or intestine. It helps preserve digestive activity.

The treatment

Depending on the pathology and the estimated duration of treatment, enteral nutrition can be provided by :

  • Nasogastric tube: the tube passes through the nose into the stomach
  • Naso-jejunal probe: the probe passes through the nose into the intestine, at the level of the jejunum.
  • Gastrostomy: the tube is inserted through the abdominal wall, directly into the stomach
  • Jejunostomy: the probe is inserted through the abdominal wall, directly into the intestine.

PARENTERAL NUTRITION

When is parenteral nutrition prescribed?

When neither oral supplementation nor enteral nutrition is possible, parenteral nutrition may be considered.
This type of nutrition involves the central intravenous administration of a complete nutrient mixture to combat undernutrition and dehydration.
To benefit from home parenteral nutrition, it must last a minimum of 14 days.

This type of nutrition is generally indicated :

  • In case of intestinal insufficiency
  • When oral or enteral feeding becomes complicated
  • When the digestive tract becomes less efficient or non-functional
  • In case of food intolerance

The treatment

Depending on the patient’s profile, the prescribing physician chooses the most appropriate mode of administration for receiving drug treatments.

There are different modes of administration:

  • Implantable chamber: a device placed under the skin and connected to a central venous line
  • Central catheter: external device connected to a large vein
  • Picc-Line: external device inserted into a peripheral vein, usually in the arm

Parenteral nutrition can be :

  • Exclusive, covering all your needs
  • Complementary to oral and/or enteral nutrition
  • Temporary
  • Final
