An Appraisal of Labor Augmentation: An Update on Current Evidence and Practice

Augmentation of labor remains the cornerstone of intrapartum care, typically employed to expedite delivery by enhancing the frequency, strength, and duration of uterine contractions. The decision to augment depends on the stage of labor and the woman's obstetric history. While up to half of all women who enter spontaneous or induced labor may require augmentation, its use is not without risk. Although augmentation in nulliparous women during the first stage of labor is generally uncontroversial, its application in multiparous women, during the second stage of labor, in breech presentation, or in women who have had a previous cesarean section remains contentious. Emerging debate also surrounds whether oxytocin should be routinely discontinued once active labor is established. In this review, we appraise contemporary evidence on the diagnosis of labor dystocia, indications, and methods for labor augmentation, outcomes, complications, and areas of clinical uncertainty. Current international guidelines are compared, and evidence-based recommendations are provided. We conclude by highlighting unresolved areas that warrant further research to inform future policy and clinical practice.
