Intravenous nutrition (IVN) and fluids calculator: preterm infants
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.
