disturbance that may be seen with malnutrition, starvation, or prolonged diuresis. Reintroduction of nutrition leads to a rapid shift of ions from serum to the intracellular space depleting potassium, phosphorus, magnesium, or calcium stores. Avoid refeeding syndrome by introducing food cautiously, monitoring clinical status and electrolytes closely, and supplementing the diet as needed.
4.6.1. Refeeding syndrome
Severe electrolyte and fluid shifts associated with metabolic abnormalities in malnourished patients undergoing “refeeding”, whether orally, parenterally, or enterally. Phosphorus, potassium, and magnesium shift to intracellular space leading to sudden drops in serum levels.
Clinical signs are varied, including neurologic dysfunction and cardiac arrhythmias
Do not offer emaciated animals (TS < 1.0) whole food initially
Always rehydrate animal first
Give B vitamins
Give oral electrolytes first
Tubefeed formula low in carbohydrates, high in fat with adequate protein
If the patient is digesting the formula, move gradually on to easily digestible solid food
