Parenteral nutrition calories, GIR and macronutrient check
From a PN order (dextrose g, amino acids g, lipid emulsion mL): total and per-kg calories, glucose infusion rate, lipid g/kg and the calorie distribution.
Inputs
3 of 6Dosing weight per your protocol.
g/day
g/day
Lipid emulsion
mL/day
h
Optional.
mL/h
Patient values are shared with every calculator.
When to use
- Checking a PN order's calories and dextrose delivery.
Pearls and pitfalls
- Adults: dextrose generally at or below 4 to 5 mg/kg/min.
- Lipid emulsion kcal/mL includes glycerol and phospholipid calories (about 1.1, 2.0 and 3.0 kcal/mL for 10%, 20% and 30%).
- Count propofol (1.1 kcal/mL) as lipid calories.
Why use
Shows every calorie source so the order can be checked line by line.
Dextrose kcal = g × 3.4; amino acid kcal = g × 4; lipid kcal = mL × emulsion kcal/mL; propofol kcal = mL × 1.1. GIR (mg/kg/min) = dextrose g × 1,000 ÷ (weight × infusion hours × 60)
