Glucose infusion rate (GIR)
Dextrose delivery in mg/kg/min from concentration, rate, and weight.

Patient values are shared with every calculator.
When to use
- Neonatal and pediatric dextrose infusions; adult parenteral nutrition.
Pearls and pitfalls
- Neonates usually start at 4 to 6 mg/kg/min.
- Adults: keep below about 4 to 5 mg/kg/min to avoid hyperglycemia and fatty liver.
- Peripheral lines generally limited to 12.5% dextrose in neonates (10% in many adult protocols).
Why use
The standard way to compare dextrose delivery across concentrations.
GIR (mg/kg/min) = dextrose % × rate (mL/h) × 10 ÷ (weight × 60)
