Cervical Effacement is the thinning of the Cervical Tissue as the body prepares for delivery.
In addition, the thinning causes a shortening of the tissue and the infant drops closer to the cervix.
This is often seen in the early portion of labor or Childbirth
Prior to this transition, the cervix has a bottleneck appearance and is quite elongated.
The length is 4 cm
Following Effacement is cervical dilation
Allows for progression of a vaginal birth
As Pregnancy continues or progresses, the cervix becomes tighter and a mucus plug is in place.
The mucus plug protects the environment of the uterus
During effacement – the cervical tissue becomes thinner and the mucus plug is loosened
It often continues until the mucus plug is passed out of the Vaginal Passage.
When this occurs it is called “bloody show”
When effacement occurs – classification is done in percentage
Occurs for 0 – 100% effacement
When at 100% – the cervix is paper thin
