Measure
Routine Oxytocin
Lactated Ringers bolus of 1000 mL will be initiated when the patient is positioned for epidural placement. Oxytocin management will continue as per the routine oxytocin protocol Routine oxytocin: per regular oxytocin protocols
Half- Dose Oxytocin
Lactated Ringers bolus of 1000 mL will be initiated when the patient is positioned for epidural placement. A half-dose oxytocin will be initiated and not increased until 60 minutes after. Half-dose oxytocin: The dose of oxytocin currently being administered will be halved and not increased until after 60 minutes initiation of labor analgesia

PRIMARY outcome

Timeframe: Request for labor analgesia up to the first 60 minutes after the epidural placement

Population: Data was not collected as the OB/MD who was a certified fetal heart rate evaluator on the team (OB/MD) left Northwestern University. The fetal heart rate data can only be collected, scored and analyzed by a certified fetal heart rate evaluator and there are none available for this project.
