Enteral hyperalimentation: an alternative to central venous hyperalimentation

Area of Science:

• Clinical Nutrition
• Gastroenterology
• Internal Medicine

Background:

• Severe protein-energy undernutrition is common in chronically ill patients.
• Causes include anorexia, hypermetabolism, and malabsorption.
• Consequences involve impaired immunity, infection risk, poor healing, and mortality.

Purpose of the Study:

• To highlight the need for therapeutic alimentation in patients with severe protein-energy undernutrition.
• To advocate for enteral hyperalimentation as the preferred method of nutritional support.
• To compare enteral hyperalimentation with central venous hyperalimentation.

Main Methods:

• Utilizing small-bore, flexible nasoenteral tubes for nutrient delivery.
• Employing appropriate feeding solutions and constant flow delivery.
• Supplementing with peripheral intravenous nutrient solutions when enteral intake is partial.

Main Results:

• Enteral hyperalimentation is generally well-tolerated and effective.
• It offers a more physiologic, safer, easier, and economical alternative to central venous hyperalimentation.
• Partial enteral tolerance can be managed with combined enteral and peripheral intravenous nutrition.

Conclusions:

• Enteral hyperalimentation is the method of choice for nutritional repletion in chronically ill patients when tolerated.
• This approach can benefit many patients currently receiving less optimal nutritional support.
• Optimizing enteral feeding strategies improves patient outcomes and reduces healthcare costs.
