What is a potential risk associated with abrupt discontinuation of parenteral nutrition in patients?

• A. Hypernatremia
• B. Refeeding syndrome
• C. Dehydration
• D. Hypotension

Answer: (B)

Refeeding syndrome is a significant risk associated with the abrupt discontinuation of parenteral nutrition, particularly in patients who are malnourished or have experienced prolonged periods of fasting. When parenteral nutrition is stopped suddenly, the body may not be able to adjust to the changes in nutrient supply, specifically the sudden influx of carbohydrates when normal feeding resumes. This can lead to severe electrolyte imbalances, especially involving phosphorous, potassium, and magnesium, which are critical for cellular function and metabolism. The process of reintroducing nutrition after a period of malnourishment can trigger a state of metabolic instability, as the body shifts from a catabolic to an anabolic state. This transition requires careful monitoring and should be done gradually to prevent the serious complications associated with refeeding syndrome, which can include cardiac issues, respiratory failure, and neurological complications. Monitoring and managing the transition between nutritional states is crucial in preventing these risks, making awareness of refeeding syndrome essential for healthcare providers managing parenteral nutrition in patients.
