Gastrointestinal Dysfunction and Feeding Intolerance in Critical Illness: Do We Need an Objective Scoring System?

Area of Science:

• Critical care medicine
• Clinical nutrition
• Gastroenterology

Background:

• Enteral nutrition is crucial for critically ill patients.
• Gastrointestinal dysfunction and feeding intolerance complicate early enteral nutrition delivery.
• Symptoms like gastroparesis, dysmotility, diarrhea, bleeding, and intra-abdominal hypertension are associated with feeding intolerance.

Purpose of the Study:

• To discuss the importance of monitoring nutritional therapy tolerance in critical care.
• To review clinical trials establishing objective measures for feeding intolerance.
• To present a tool for guiding enteral nutrition regimen delivery.

Main Methods:

• Review of clinical trials on enteral nutrition in critical illness.
• Analysis of objective measures for gastrointestinal dysfunction and feeding intolerance.
• Evaluation of strategies for managing feeding intolerance and optimizing enteral feeding.

Main Results:

• Feeding intolerance correlates with adverse outcomes: prolonged mechanical ventilation, longer ICU stays, and increased mortality.
• While scoring systems have prognostic value, their role in directing therapy requires further clarification.
• Protocols for monitoring tolerance and providing individualized care optimize early enteral feeding.

Conclusions:

• Careful selection of monitors and prompt management of intolerance are essential for safe and effective enteral feeding.
• Protocols that balance monitoring with individualized care enhance early enteral nutrition in critical illness.
• Objective measures and defined intolerance criteria aid in optimizing nutritional therapy for critically ill patients.
