The new guidelines:
The active phase of labor begins when the cervix is dilated 6 cm (previously, 4 cm).
Considering a new definition for the start of
the active phase of labor: 6 cm cervical dilation, instead of 4 cm.

ACNM (2008), based on an in - depth review
of literature on oral intake during
labor, reported that American hospitals tend to limit oral intake during the latent
phase of labor to clear liquids, and during the
active phase to sips
of water or ice chips.
The researchers defined
active phase labor arrest as 1 cm or less
of labor progress over 2 hours in women who entered
labor spontaneously and were at least 4 cm dilated at the time arrest was diagnosed.
In all
phases of labor, before pushing, it's generally better to be
active and upright during contractions.
In this study, the 95th percentile rate
of active phase dilation was substantially slower than the standard rate derived from Friedman's work, varying from 0.5 cm / h to 0.7 cm / h for nulliparous women and from 0.5 cm / h to 1.3 cm / h for multiparous women (the ranges reflect that at more advanced dilation,
labor proceeded more quickly)(Table 2).
The first stage
of labor has been historically divided into the latent
phase and the
active phase based on the work by Friedman in the 1950s and beyond.
Labor may not naturally accelerate on its own (
active phase) until 5 cm
of dilation and introducing interventions like oxytocin augmentation or performing a cesarean for failure to progress when the mother's or baby's condition is stable is not recommended.
Active labor is the second
phase and part
of the first stage in the
laboring process.
