About

Feed volumes are advanced by the specified amount at each interval until the goal volume is reached.

Current TFI (mL/kg/day) = (Volume per feed × feeds per day) ÷ weight (kg)

Advancement rate (mL/kg/day) = (mL advanced per feed × advances per day × feeds per day) ÷ weight (kg)

Time to goal = number of advances × advance interval (hours)

For continuous feeds, volume is expressed as mL/hr and daily intake = mL/hr × 24.

The IV wean suggestion assumes total fluid intake remains constant: for each mL increase in enteral feeds, IV rate decreases by the equivalent amount.

Goal feed volume rounded to the nearest 0.5 mL (bolus) or 0.1 mL/hr (cont). Feed volumes in schedule rounded to the nearest mL (bolus) or 0.1 mL/hr (cont.) Time to goal is rounded to the nearest 0.25 days. IV wean rate it rounded to 2 decimal places.

Feeding Guidelines

Trophic feeds, also known as non-nutritive feeds, minimal enteral nutrition, or gut priming feeds, are small volume feeds, approximately 10-20 mL/kg/day. Trophic feeds may be maintained for several days for the smallest babies. Typically, advancing feeds by 10-30 mL/kg/day is well-tolerated, up to a goal TFI of 150-160 mL/kg/day.
