GIR Calculator (Glucose Infusion Rate)

Your details

Body weight of the neonate or infant. Most neonatal GIR targets are based on weight in kg.
kg
Switch to reverse-solve to find the infusion rate needed for a specific GIR target.
Percentage concentration of the dextrose solution (e.g. 10 for D10W, 12.5 for D12.5W). This equals g/dL numerically.

Total GIR is 3.89 mg/kg/min.

  • GIR below 4 mg/kg/min is insufficient to maintain euglycemia in most neonates and may cause hypoglycemia or catabolism.
  • This GIR delivers approximately 5.6 g of glucose per kg per day.
  • GIR is a guide, not a substitute for frequent blood glucose monitoring and clinical judgment.

Next stepVerify the result against current blood glucose, clinical status, and institutional neonatal fluid protocols before any IV rate change.
