Background and Aims Preterm infants (PI) are often discharged from the NICU with suboptimal growth. It seems obvious that a commercial nutrition calculating program (NCP) could help to compute macro- and micro nutrients more easily. The aim of this intervention study was to determine whether a NCP could optimise the growth of PI.
Methods In 78 PI (GA≤32+0) cases grouped in 35 PI before (CG) and 43 after (IG) the implementation of the NCP Nutrium weight, length and head circumference at birth, day 28, GA 36 and discharge were compared.
Additionally daily intake of total fluid, energy, carbohydrate (CH), aminoacids (AA), fatty acides (FA), Na, K, Ca, Mg, P, Fe, Zn and vitamine A, E and D in postnatal weeks 1–7 were recorded and compared.
AA, CH, Ca, P, Zn intake was significantly increased. FA and total energy was marginally increased in week 1. Vitamin A, E and D intake was optimised in IG and tended to be overdosed in CG (Recommendations based on Tsang/ESPGHAN).
Conclusion By using the NCP growth overall and especially length-growth was significantly optimised in PI (GA ≤32+0) trough optimising intake of CH, AA, Ca, P, Zn. In the IG it was more likely that Vitamins were dosed correctly.
