Effacement
Effacement
Effacement (/ɪˈfeɪsmənt/) is a term used in obstetrics to describe the process by which the cervix prepares for childbirth.
Etymology
The term "effacement" is derived from the French word "effacer", which means to erase or wipe out. In the context of childbirth, it refers to the thinning and shortening of the cervix.
Definition
Effacement is the process by which the cervix thins, shortens and becomes more pliable in preparation for childbirth. It is measured in percentages, from 0% (no effacement) to 100% (fully effaced). Effacement is one of the physical changes that occur in the cervix along with dilation during the first stage of labor.
