Abstract
Background: Neonatal sepsis remains a major cause of morbidity and mortality, particularly during the first weeks of life. Early-onset sepsis (EOS), occurring within the first 72 hours after birth, is mainly associated with maternal and perinatal risk factors, whereas late-onset sepsis (LOS) is linked to healthcare exposure and neonatal vulnerability. Early recognition remains difficult because clinical manifestations are often nonspecific.
Aim: This review summarizes current evidence on the epidemiology, aetiology, risk factors, clinical presentation, diagnosis, prevention, treatment, and multidisciplinary management of neonatal sepsis, with emphasis on EOS and LOS.
Methods: A narrative literature review was conducted using PubMed/MEDLINE, EMBASE, and ClinicalKey. Evidence addressing neonatal sepsis definitions, risk factors, diagnostic approaches, biomarkers, antimicrobial therapy, prevention, complications, and antimicrobial stewardship was reviewed and synthesized.
Results: EOS is commonly associated with maternal Group B Streptococcus colonization, intra-amniotic infection, prolonged rupture of membranes, and prematurity. LOS is associated with prematurity, prolonged hospitalization, invasive procedures, and healthcare exposure. Clinical signs include respiratory, cardiovascular, neurological, and gastrointestinal abnormalities, but none reliably excludes infection. Blood culture remains central to diagnosis, while inflammatory biomarkers can support clinical assessment. Risk-based assessment and serial clinical observation can reduce unnecessary antibiotic exposure in well-appearing neonates. Suspected sepsis requires prompt cultures and empiric antimicrobial therapy, commonly involving ampicillin or benzylpenicillin with an aminoglycoside, followed by modification according to microbiological results and local resistance patterns. Supportive respiratory, circulatory, and metabolic management remains essential.
Conclusion: Effective neonatal sepsis care requires early recognition, risk-based assessment, timely antimicrobial treatment, infection prevention, and antimicrobial stewardship within a coordinated multidisciplinary pathway.
