Refeeding syndrome--awareness, prevention and management

Area of Science:

• Oncology
• Nutritional Science
• Critical Care Medicine

Background:

• Refeeding syndrome is a critical, often overlooked complication.
• Head and neck cancer patients are at high risk due to malnutrition and dysphagia.
• Early recognition of at-risk patients is vital for prevention.

Purpose of the Study:

• To emphasize the importance of refeeding syndrome in head and neck cancer patients.
• To elucidate the pathophysiology of refeeding syndrome.
• To review current evidence, guidelines, and identify research gaps.

Main Methods:

• Literature review of existing evidence and guidelines.
• Analysis of pathophysiology and risk factors for refeeding syndrome.
• Synthesis of information for clinical recommendations.

Main Results:

• Refeeding syndrome involves hypophosphatemia and electrolyte shifts post-starvation.
• Chronically undernourished patients and those with dysphagia are at highest risk.
• Gradual refeeding (starting at 10 kcal/kg/day) with supplements is recommended.

Conclusions:

• Refeeding syndrome is preventable and potentially fatal.
• Proactive identification and management are key.
• Further high-quality research is needed due to limited evidence.
