Intravenous nutrition (IVN) and fluids calculator: preterm 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 for the majority of infants who require IVN using Starship Child Health NICU standard IVN solutions.

  • Our standard solutions are designed to meet the infant's usual nutritional requirements in a relatively small volume of fluid.

  • P100 is the standard (amino acid and glucose) solution we use and can be administered via a central or peripheral line.

  • P100 is given at a maximum volume of 96 ml/kg/day for infants ≤ 1000 g, which will provide 4.0 g/Kg/day of protein.

  • For Infants >1000 g, the usual maximum is 90 ml/Kg/day providing 3.8 g/Kg/day of protein.

  • We also use a standard lipid solution with vitamins added called PremSMOF.

  • The remainder of the fluid requirement is made up with 10% glucose.

  • Occasional infants will require an individualised IVN solution.

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

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.

  • Please cons ider whether the infusions should be made up in 5% glucose, 10% glucose, 0.45% NaCl, or 0.9% NaCl.

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 4g/kg/day from the IVN amino acid solution, and a total of 4.5g/kg/day of combined IVN and oral protein.

Additional glucose

 Glucose. Heparin (250U/500ml) is not necessary unless running through a separate lumen.
