Background:

Preterm newborns require the use of the best and most current strategies to treat and prevent both acute pathology and associated sequelae. This study aimed to compare the differences in the management of preterm newborns over 10 years in a tertiary hospital in Spain and its impact on height, weight, and neurological development in the medium term.

Methods:

We conducted a retrospective, observational, and analytical study examining the management and clinical variables in preterm newborns under 32 weeks of gestational age who were born in our hospital in 2011 and 2021.

Results:

Twenty-six newborns were included in the study. Significant differences in magnesium sulfate use, continuous positive airway pressure immediately after birth, and non-invasive mechanical ventilation during hospitalization were observed. Differences were found in the use of parenteral nutrition and the timing of initiation of enteral feeding. We did not observe differences in the neurological or weight evolution in the medium term.

Conclusions:

Significant differences in managing preterm newborns in these 10 years were observed. Lower mortality and alterations in central nervous system ultrasound and, significantly, less growth retardation during admission in 2021 have been observed; however, it does not manifest with improvement in long-term somatometrics or neurological prognosis.
