What is the maximum tolerance volume for continuous feeds in infants under 12 months?

The maximum tolerance volume for continuous feeds in infants under 12 months is based on their immature digestive systems and the need for gradual adaptation to enteral nutrition. A tolerance volume of 6 mL/kg/hour is established as a safe and effective amount for continuous enteral feeding. This guideline allows for adequate nutrient absorption while minimizing the risk of gastrointestinal complications such as diarrhea, discomfort, or feeding intolerance.

In this age group, infant physiology must be considered; they have higher metabolic rates and smaller stomach capacities than older children or adults. Thus, feeding regimens are designed to accommodate these characteristics while providing necessary nutrition. The choice of 6 mL/kg/hour reflects a balance between ensuring sufficient caloric intake and avoiding overloading their still-developing gastrointestinal tract.

The other options provide lower infusions that may not meet the nutritional needs effectively or are inadequate volumes for continuous feedings based on the energy demands of infants. Thus, selecting 6 mL/kg/hour as the maximum tolerance volume aligns with pediatric feeding guidelines for optimal growth and tolerance.
