Enteral feeding.

Area of Science:

• Clinical Nutrition
• Gastroenterology
• Critical Care Medicine

Background:

• Enteral nutrition is widely adopted for nutritional support in malnourished and ICU patients.
• Numerous studies on its efficacy, administration, and outcomes are published annually.
• A critical review of recent evidence is needed to navigate the extensive literature.

Purpose of the Study:

• To review evidence-based studies on enteral nutrition from December 2002 to the present.
• To critically evaluate studies on the efficacy, administration techniques, and patient outcomes of enteral nutrition.
• To provide readers with rapid access to important publications in the field.

Main Methods:

• Comprehensive literature search of evidenced-based studies on enteral nutrition.
• Critical review and synthesis of selected articles published from December 2002 onwards.
• Categorization of studies based on specific topics such as nutritional status, combined nutrition, pancreatitis, infant rehydration, feeding routes, and specialized conditions.

Main Results:

• The review covers diverse topics including nutritional status impact on outcomes, combined enteral and parenteral nutrition, enteral nutrition in pancreatitis, infant rehydration, gastric vs. intestinal feeding, nutrition for hip fractures and pressure ulcers, immunonutrition, and infant enterocolitis.
• Systematic reviews and clinical guidelines related to enteral nutrition are also discussed.

Conclusions:

• Enteral nutrition is an established and accepted method of nutritional support.
• The specific conditions for which enteral nutrition improves patient outcomes and optimal delivery methods require further clarification.
• Many existing studies suffer from small sample sizes, lack of placebo arms, or insufficient attention to baseline nutritional status.
