A recent study conducted by the Brazilian Network of Neonatal Research (RBPN) has demonstrated that changes in neonatal care practices, specifically reducing unnecessary antibiotic use and enhancing early breast milk feeding, have led to an 18.5% decrease in the incidence of late-onset sepsis. This infection is a significant cause of mortality among very low birth weight premature infants. The study was carried out across 12 neonatal centers from 2021 to 2023, highlighting sustainable practices in neonatal care that could potentially save lives.

Sepsis, a severe infection often affecting babies born weighing less than 1.5 kg, can manifest in two forms: early-onset sepsis, which occurs within the first three days of life and is typically linked to maternal factors, and late-onset sepsis, which is associated with environmental factors and appears after the initial days. As many premature infants are born with immature immune systems and rely on life-supporting devices such as mechanical ventilation, they are especially vulnerable to infections, which underscores the importance of these new care strategies.

The findings from this study advocate for a reevaluation of current neonatal practices, encouraging healthcare providers to prioritize breast milk as a crucial nutritional source while minimizing antibiotic exposure. Such changes not only address immediate health concerns but may also contribute to improving long-term health outcomes for premature infants, paving the way for enhanced neonatal care in Brazil and possibly influencing practices worldwide.
