How to reduce the risk of GBS EOD?
Intrapartum antibiotic prophylaxis to reduce the risk of GBS EOD is based on a two-pronged approach: 1) decreasing the incidence of neonatal GBS colonization, which requires adequate maternal drug levels, and 2) reducing the risk of neonatal sepsis, which requires adequate antibiotic levels in the fetus and newborn. These therapeutic goals are considered when developing recommendations regarding drug choice and dosage for intrapartum GBS prophylaxis. Intrapartum antibiotic prophylaxis regimens for women colonized with GBS are presented in Figure 3.
