TOOLS / CALCULATOR 01
Glucose infusion rate
GIR calculator · mg/kg/min
Enter a patient weight, then add the glucose or carbohydrate percentage and daily volume for each fluid or feed. The calculator combines the contributions from your entries.
Patient details
Fluid details
Values are based on a small purple scoop. Please consult your neonatal dietitian.
Volume: — mL/day · — mL/hour
IV glucose GIR: — mg/kg/min
Enteral carbohydrate delivery: — mg/kg/min
Custom glucose/carbohydrate delivery: — mg/kg/min
Delivery (mg/kg/min) = concentration (% or g/100 mL) × volume (mL/kg/day) ÷ 144. IV glucose GIR uses glucose concentration; feed delivery uses total carbohydrate concentration.
Maintenance GIR: Guideline Reference
Starting doses will be lower, for illustrative use only.
| Guideline | Population | Reference values (mg/kg/min) |
|---|---|---|
| ESPGHAN 2018 | Preterm | Target 8–10; maximum 12 |
| ESPGHAN 2018 | Term | Target 5–10; maximum 12 |
| NICE NG154 | Preterm and term | 6.25–11.1 |
Feed Carbohydrate Reference
For reference only from manufacturer and ESPGHAN values. Some Maxijul concentrations are not shown as their osmolality is unlikely to be tolerated. Always confirm values with your neonatal dietitian.
| Feed | No Maxijul | 1 purple scoop per 50 mL | 1 purple scoop per 25 mL |
