Intrapartum Atosiban Treatment During Tachysystole and Non-reassuring Fetal Monitoring: A Retrospective Cohort Study.

Background: Uterine tachysystole during labor can lead to a decrease in fetal oxygen saturation and intracerebral oxygen saturation. Acute tocolysis using atosiban can inhibit uterine smooth muscle activity, potentially improving fetal status and facilitating vaginal delivery or allowing time to prepare for operative delivery.

Objectives: To compare maternal and neonatal outcomes in cesarean and vaginal deliveries following atosiban administration during fetal prolonged deceleration and tachysystole at gestational age 37 0/7 to 43 0/7 weeks.
