In 2014, the ACOG released a consensus statement, “Safe Prevention of the Primary Cesarean”. This extended the 2nd stage of labor by 1 hour. Was this evidence-based? New data suggest it was not, and may be harmful. In 2016, Leveno et al (Parkland Hospital) issued the first clinical commentary as a rebuttal to these changes citing lack of evidence to support the prolongation. In this session, we will review the upcoming publication (ahead of print) from Nelson, McIntire, and Leveno (Parkland Hospital) again calling these 2014 labor time-limits into question, presenting new data.
