Abstract

Objective: Antibiotics are one of the most widely used medications in today's neonatal intensive care units. Indiscriminate antibiotic usage persists in preterm newborns who are symptomatic due to factors linked to prematurity rather than being septic. Previous studies in older infants suggest that prior antibiotic administration is associated with possible dysmotility and microbial dysbiosis in the intestinal tract. We hypothesize that early antibiotic administration impacts high-risk preterm infants' tolerance to enteral feeding advancement.

Study design: As part of the Routine Early Antibiotic Use in SymptOmatic Preterm Neonates study, symptomatic preterm newborns without maternal infection risk factors were randomized to receive or not receive antibiotics, with C1 receiving antibiotics and C2 not. Of the 55 newborns that underwent pragmatic randomization, 28 preterm neonates in group C1 received antibiotics.

Results: The premature neonates in the randomized groups who received antibiotics and those who did not showed no differences in sustained feeding tolerance.

Conclusion: Our investigation of the risk of feeding issues in babies who get antibiotics early in life revealed no differences between neonates who received antibiotics and those who did not when the randomized controlled trial data alone was reviewed. Given the sample sizes, it is uncertain if the preceding analysis is powerful enough to detect differences (a significant percentage of neonates who were randomly assigned to NOT get antibiotics subsequently received early treatment due to changing clinical conditions). This affirms the requirement for a meticulously designed prospective randomized study.

Key points: · Defining feeding tolerance for the first time in neonates.. · Patients from the REASON trial were evaluated.. · Preterm neonates were the focus of this study..
