What are the three phases in stage one of labor?

In stage one of labor, the correct classification divides it into three phases: latent, active, and transition.

The latent phase is the initial stage, where the cervix begins to efface and dilate. Contractions are often mild and irregular during this phase, allowing the laboring person to remain relatively comfortable and engaged in routine activities.

The active phase follows, where the contractions become more intense, closer together, and usually more regular. During this time, the cervix dilates from about 6 cm to 10 cm, marking significant progress in labor.

The transition phase is the final part of stage one, characterized by the most intense contractions and rapid dilation to full enlargement. This phase is often the shortest but can be the most challenging, as the body prepares for the pushing stage of labor.

Recognizing these three phases is crucial for healthcare professionals to provide appropriate support and manage pain effectively during labor. Understanding the distinctions between these phases allows caregivers to monitor the progress of labor and anticipate the needs of the laboring person.
