Management of Term Newborns at 39 Weeks Gestation without Group B Streptococcus Screening

Evaluation of Intrapartum Risk Factors

The American Academy of Pediatrics recommends administering intrapartum antibiotic prophylaxis (PAI) if any of the following risk factors are present: rupture of membranes ≥18 hours, maternal temperature ≥38.0°C (100.4°F) during labor, preterm birth <37 weeks, or bacteriuria due to Group B Streptococcus (GBS) during the current pregnancy 1, 2, 3
The Centers for Disease Control and Prevention (CDC) also recommends considering PAI for women with a history of a previous infant with GBS disease 4

The American Academy of Pediatrics recommends immediate evaluation, including blood culture, complete blood count with differential and platelets, chest radiograph if respiratory signs are present, and lumbar puncture if the newborn is stable and sepsis is suspected 1, 2, 3
The American Academy of Pediatrics also recommends starting empirical antibiotics immediately after obtaining cultures, with ampicillin IV and gentamicin IV as the recommended regimen 1, 2, 6

The American Academy of Pediatrics recommends limited evaluation, including blood culture and complete blood count with differential and platelets, and starting empirical antibiotics pending culture results 1, 2, 7
The CDC recommends a minimum hospital observation period of 48 hours for newborns with chorioamnionitis 2

The American Academy of Pediatrics recommends observation for 48 hours if rupture of membranes is <18 hours, with no laboratory evaluation required and close monitoring for signs of sepsis 1, 2
If rupture of membranes is ≥18 hours, the American Academy of Pediatrics recommends limited evaluation, including blood culture and complete blood count with differential and platelets, and observation for 48 hours 1, 2

The American Academy of Pediatrics recommends routine care and observation for 48 hours, with the possibility of early discharge at 24 hours if the newborn is term, has adequate PAI, and has access to medical care, with follow-up in 48-72 hours 1, 2

The American Academy of Pediatrics recommends monitoring for hypoglycemia, polycythemia, and birth trauma in LGA newborns, in addition to the standard management algorithm for GBS prevention 1, 4

The CDC recommends not delaying necessary obstetric procedures to complete 4 hours of PAI, and not using erythromycin as an alternative for PAI in penicillin-allergic women with high-risk anaphylaxis 2
The American Academy of Pediatrics recommends not administering oral antibiotics to colonized mothers during prenatal screening, and not performing routine lumbar punctures in well-appearing newborns with chorioamnionitis 1, 2, 3
