Despite the frequency with which obstetrics providers manage labor, evidence has emerged in the past few years challenging our historical understanding of normal labor progress over time. We are also confronted with the dearth of evidence to guide the optimal management of labor. With these data, we are presented with both the challenge of changing practice at the bedside and the opportunity for new discovery to optimize labor and delivery outcomes. Given the sheer frequency of labor and delivery, changes that improve outcomes even by a small magnitude have the potential to dramatically impact labor-associated morbidity at the population level.
尽管产科医生经常管理分娩，但过去几年出现的证据挑战了我们对正常分娩过程随时间推移的历史理解。我们还面临着缺乏证据来指导最佳分娩管理的问题。有了这些数据，我们不仅面临着改变床边实践的挑战，还有机会进行新的发现，以优化分娩结果。鉴于分娩的频率如此之高，即使是微小的改善也有可能在人群水平上显著降低与分娩相关的发病率。
