oxytocin infusion and terbutaline are both used to stimulate or inhibit uterine contractions, respectively. Neither of them are indicated for chorioamnionitis, which requires delivery rather than prolonging the pregnancy.

antibiotics and corticosteroids are both used to prevent or treat infection and promote fetal lung maturity, respectively. However, they are not sufficient to treat chorioamnionitis, which requires delivery as the definitive therapy. Antibiotics may be given before or during delivery to reduce the risk of neonatal sepsis, but they do not eliminate the need for delivery.

chorioamnionitis is a serious infection of the placental tissues that can cause fetal and maternal morbidity and mortality. The best management is to deliver the baby as soon as possible to prevent further complications.

corticosteroids and magnesium sulfate are both used to prevent or treat preterm labor and fetal neuroprotection, respectively. However, they are not indicated for chorioamnionitis, which requires delivery as the definitive therapy. Magnesium sulfate may also increase the risk of maternal hypotension and respiratory depression, which can worsen the condition.
