Perfil de prescripciones de nutrición parenteral y evolución ponderal en prematuros menores de 36 semanas en un hospital de los andes peruanos. Un estudio descriptivo

Introduction: The guidelines bring together the best levels of scientific evidence and through their use the quality of care is improved, therefore it is important to describe the parenteral nutrition prescription profile in premature infants in a Peruvian hospital and their weight evolution on the fourteenth day. Objective of the study: To describe medical prescriptions for neonatal parenteral nutrition and their adherence to local reference guidelines based on ESPGHAN, ESPEN, ESPR; as well as showing the weight evolution on the fourteenth day. Material and Methods: Observational, descriptive, retrospective study in the neonatal intensive care unit of the “Ramiro Prialé Prialé” National Hospital, period 2022. Parenteral nutrition prescriptions that meet inclusion and exclusion criteria were considered and compared with the recommendations of the local guide; Weight gain on the 14th day was also measured using a previously validated formula. Results: 68 patients with a minimum gestational age of 27 and maximum of 36 weeks were studied; minimum weight of 1000 gr and maximum of 3500 gr. It was found that on the first day the average energy prescription was 60.58 kcal/kg/day, protein intake 2.57 gr/kg/day and lipid intake 2.18 gr/kg/day; corresponding to 72.06%, 69.12% and 57.35% of adherence to the guidelines, on the fifth day these values increased, in turn this corresponded to an adherence of 100%, 94.12% and 97.06 % according to reference guides. The average weight gain was 12.29 gr/kg/day on the fourteenth day. Conclusions: Adherence to the ESPGHAN, ESPEN, ESPR guidelines in the prescription of parenteral nutrition is acceptable, with this being much higher on the fifth day. It is likely that this is related to the weight evolution found.
