What is the recommended rate to start Kate Farms (peptide-based nutrition) peg (percutaneous endoscopic gastrostomy) feeding to prevent refeeding syndrome?

Starting Kate Farms PEG Feeding to Prevent Refeeding Syndrome

For patients at risk of refeeding syndrome, Kate Farms peptide-based nutrition should be started at 5-15 kcal/kg body weight per day via PEG tube, with careful monitoring of electrolytes and gradual advancement of rate by 20 mL/h every 24 hours until nutritional targets are reached. 1

Risk Assessment for Refeeding Syndrome

Before initiating Kate Farms feeding, assess for refeeding risk factors:

• Weight loss >15% in past 3-6 months
• Little or no nutritional intake for >10 days
• Low baseline electrolytes (potassium, phosphate, magnesium)
• History of chronic malnutrition, alcoholism, cancer, or prolonged fasting
• BMI <16 kg/m²

Initial Feeding Protocol Based on Risk

High Risk Patients:

• Start at 5-10 kcal/kg/day (approximately 10 mL/h of standard Kate Farms formula)
• Monitor electrolytes (phosphate, potassium, magnesium) every 12 hours for first 48 hours
• Provide prophylactic electrolyte replacement and thiamine supplementation before feeding
• Maintain 40-60% carbohydrate, 30-40% fat, and 15-20% protein composition 1

Moderate Risk Patients:

• Start at 10-15 kcal/kg/day (approximately 15-20 mL/h)
• Monitor electrolytes daily for first 3 days

Advancement Protocol

1. Begin with initial rate as determined by risk assessment
2. After 24 hours of stable electrolytes, increase rate by 20 mL/h 1
3. Continue daily increases of 20 mL/h until nutritional target is reached (usually by day 5-6)
4. Full nutritional targets should be achieved within 5-10 days depending on risk level

Monitoring Requirements

• Serum electrolytes (phosphate, potassium, magnesium, calcium)
• Blood glucose levels (every 6 hours initially)
• Fluid balance and signs of edema
• Cardiac monitoring if severe malnutrition present

Special Considerations

• For gastrostomy tubes, feeding can technically begin within 2-4 hours after uncomplicated placement 1, but in patients at risk for refeeding syndrome, the cautious approach with lower initial rates should still be followed
• Continuous pump feeding is preferred over bolus feeding for patients at risk of refeeding syndrome
• Avoid water trials prior to commencing EN via gastrostomy tube 1

Common Pitfalls to Avoid

1. Starting too fast: The traditional "start low, go slow" approach is critical for preventing refeeding syndrome, despite some newer research suggesting higher calorie protocols may be safe in certain populations 2

2. Inadequate monitoring: Failure to check electrolytes frequently in the first 48-72 hours can miss early signs of refeeding syndrome

3. Forgetting thiamine supplementation: Thiamine should be given before starting feeding to prevent Wernicke's encephalopathy

4. Excessive fluid administration: Can worsen edema and cardiac complications in refeeding syndrome

5. Ignoring clinical signs: Weakness, confusion, respiratory distress, or edema may indicate developing refeeding syndrome even before laboratory abnormalities appear

By following this protocol, the risk of refeeding syndrome can be minimized while still providing essential nutrition through the Kate Farms peptide-based formula via PEG tube.
