All patients in preterm labor should be considered at high risk for neonatal GBS sepsis. Patients in preterm labor with the potential to deliver should receive prophylactic antibiotics against GBS, unless GBS culture is negative. Prophylactic antibiotics should be administered when the diagnosis of preterm labor is made and should be continued until delivery or for a minimum of 72 hours. Patients should be re-treated if preterm labor recurs or when the patient enters labor at term depending upon culture results.
