Abstract

Objective

To determine the effects of empiric antibiotic therapy within the first 72 hours after birth, in cases of suspected early-onset sepsis without positive blood cultures, on the neurodevelopment of VLBW infants.

Methods

Cohort study conducted from January 2014 to December 2021, included neonates from 24 to 32 weeks' gestation. They were categorized based on receiving early antibiotics. Outcomes measured included neonatal morbidities and scores on the Bayley Scales of Infant Development, Third Edition (BSID-III), at 12 to 36 months corrected age.

Results

Of 261 VLBW infants 52.9% (n = 138) received empiric antibiotics within the first 72 hours, while 47.1% (n = 123) did not. Multivariate analysis revealed no association between early antibiotics and neurodevelopmental delay. Severe intraventricular hemorrhage independently correlated with delays, while late-onset sepsis and bronchopulmonary dysplasia contributed to specific motor and cognitive delays. Propensity score matching (PSM) was conducted using various models that included gestational age, late-onset sepsis, severe intraventricular hemorrhage, bronchopulmonary dysplasia, and clinical chorioamnionitis. However, antibiotic use was not independently associated with an increased risk of developmental delay in the applied models.

Conclusion

Although the use of antibiotics did not emerge as an independent factor contributing to developmental delay, VLBW infants who received antibiotics had more morbidities during their NICU stay.
