What is defined as the first stage of dilation in labor?

The first stage of dilation in labor is commonly segmented into the latent and active phases. Latent labor is specifically characterized by the initial stage of cervical dilation, where contractions begin and the cervix starts to efface and open, typically achieving dilation of 0 to around 6 centimeters. This phase can be prolonged and may not be concurrent with frequent contractions, allowing for variability in the duration of this stage.

In contrast, active labor follows the latent phase and is defined by more intense and frequent contractions leading to more rapid changes in cervical dilation. Recognizing latent labor is important for healthcare providers to appropriately manage expectations and maintain comfort for the laboring individual during this sometimes lengthy initial phase. This distinction helps in understanding the progress of labor and making informed decisions regarding care and interventions, thereby ensuring both maternal and fetal well-being.
