Enteral Feeding

The goal of this feasibility study is to assess the feasibility to implement a feeding strategy for preterm infants. The main questions it aims to answer are: * Is it feasible to implement the PoP-intervention in a level 3a category Neonatal intensive care unit? * Is the PoP-intervention acceptable for parents of preterm infants and health care personnel working in Neonatal intensive care unit? Parents of preterm infants and health care personnel will be asked to follow a protocol of a feeding strategy based on the preterm infants development and cues throughout the NICU-stay.

The study will be carried out as a prospective randomized controlled clinical study to determine the effect of tactile/kinesthetic stimulus program on preterm infants on transition time to full sucking, sucking success and hospital stay.

It is a two-arm prospective interventional study. 40 babies in both groups will be enrolment in the study. In the intervention group, babies will take 1 ml/kg/day of the study product (ULTRA PREMIUM) after full enteral feeding. Supplementation will continue until discharge or the 36th week. Blood samples will be taken for serum Total antioxidant capacity and Malondialdehyde levels before the intervention and on the 14th day of the control group. At the end of the study, serum will be taken again for control values. Daily lipid intake amounts will be recorded through breast milk analysis. Lipid profile will be monitored weekly The growth parameters of babies will be monitored daily It will be evaluated at the end of the study in terms of ROP, BPD, and NEC. At the end of the study, the data of babies in both groups will be compared.

Determine the effect of high-dose pancreatic enzyme supplementation on nutritional indicators and clinical course in critically ill patients undergoing enteral nutrition.
