The American Academy of Pediatrics (AAP) issues guidance for managing an asymptomatic infant < 37 weeks of gestation born to a mother with risk factors for neonatal sepsis. The goal is to provide or discontinue antibiotic therapy based on need.
Parameters: asymptomatic neonate < 37 weeks of gestation AND risk factors for neonatal sepsis (maternal chorioamnionitis, rupture of membranes >= 18 hours, inadequate intrapartum antibiotic prophylaxis)
Initial management:
(1) Blood cultures are collected from the neonate at birth.
(2) Broad spectrum antibiotics (ampicillin and aminoglycoside, or altnerative) are started after blood cultures are collected.
(2) A WBC with differential and CRP are collected 6-12 hours after birth.

Discontinue antibiotics, discharge when infant meets discharge criteria. |
where:
• If antibiotics are given because of abnormal laboratory tests and maternal intrapartum antibiotics, then discontinue at 48 hours if probablility of sepsis is low.
• If laboratory tests are abnormal but the mother did not get intrapartum antibiotics then management depends on monitoring the infant.
• The diagnosis of chorioamnionitis can be subjective and may require discussion with the obstetrician.
