Requirement for oxytocin augmentation in spontaneous parturition is associated with the maternal serum steroid hormones assessed by liquid chromatography coupled to the tandem mass spectrometry.

This research provided reference ranges for the selected maternal serum steroid hormones at the beginning of parturition. Association of corticosterone, dehydroepiandrosterone, and androstenedione with the need for the oxytocin infusion usage has been established. Dehydroepiandrosterone could be potential predictor of oxytocin infusion augmentation for progression of the parturition.
