Intravenous nutrition (IVN) and fluids calculator: term infants

This document is only valid for the day on which it is accessed. Please read our .

This calculator is designed to provide maximal nutritional intakes in the majority of infants who require IVN that can be provided by the Starship NICU standard IVN solutions.

  • Term infants should receive only P100.  This is usually given at a maximum volume of 71ml/kg/day in term infants, which will provide 2.9g/kg/day of protein.  Some infants may require 90ml/kg/day (3.5g/kg/day).

  • Occasional infants will require an individualised IVN solution - contact dietitian if this is required.

Please consider carefully whether the infant requires IVN or whether 10% glucose (with or without additives) can be used.  In general, larger infants (>1500g) who are expected to feed quickly should not be prescribed IVN.

Age of baby
Working weight
Planned daily fluid intake
to be given over
IVN and lipid may be given over a period <24 hours if the baby is receiving intermittent infusions that interrupt fluid administration.
Arterial line fluids
Other infusions
(excluding insulin)
  • Consider whether the infusions should be made up in 5% glucose, 10% glucose, 0.45% NaCl, or 0.9% NaCl.
Oral feeds
ml every hours
IVN amino acid solution
Solution P100  (You cannot use Starter solution)
Maximal desired intake: ml/kg/day.
This is the most that you want the baby to receive, even if the baby can tolerate a greater intake.
Maximum possible intake:
Based on current oral feeds and the maximum you have set above.
Actual intake:
  • Protein intakes will be limited to 3.5g/kg/day from the IVN amino acid solution, and a total of 4.0g/kg/day of combined IVN and oral protein.
Additional glucosee
Glucose. Heparin (250U/500ml) is not necessary unless running through a separate lumen.
