Reprise - Episode 242: New Labor Guidance Part 2

ACOG Clinical Practice Guideline #8 redefines the management of the second stage of labor, shifting from rigid time-based thresholds toward an individualized clinical approach. While prolonged second stage is defined as three hours or more for nulliparous patients and two hours or more for multiparous patients, clinicians must prioritize ongoing fetal descent and specific clinical factors over strict adherence to these durations. Research indicates that extending the second stage increases risks of neonatal acidemia, NICU admission, and maternal lacerations, necessitating careful evaluation of fetal position and station. Effective management strategies include initiating pushing immediately upon full dilation, utilizing manual rotation to correct malpositions like occiput transverse or posterior, and performing a thorough assessment for operative vaginal delivery before resorting to cesarean section. This guidance emphasizes balancing the goal of vaginal delivery with the mitigation of maternal and neonatal morbidity.
