This calculator determines how much sugar (in mg/kg/min) an infant is receiving.

Enter the infant’s weight, then specify the various inputs – dextrose percentage and flow rate for one or two infusions, and type of milk and hourly milk volumes, and use of polycal (a sugar) in terms of specifying how many grams are added to each 100 ml of milk.
  • Breast milk sugar content   7.1 g / 100 ml
  • Term formula sugar content   7.1 g / 100 ml
  • Pre-term formula sugar content   8.5 g / 100 ml
  • Assumption made that all enteral feeds are absorbed
  • Any infant requiring a glucose load of 10 mg/kg/minute to maintain normoglycaemia should be investigated for hyperinsulinism.
