Dilation is a measure of how open the cervical os is. It is usually the most important indicator of progression through the first stage of labour. Dilation is measured by way of a digital cervical exam with the care providers fingers. Dilation is described using centimetres; closed, 1cm, 2cm, 3cm, etc until fully dilated at 10 cm.

Partograph. A partogram or partograph is a composite graphical record of key data (maternal and fetal) during labour entered against time on a single sheet of paper. Relevant measurements might include statistics such as cervical dilation, fetal heart rate, duration of labour and vital signs.
Cervical dilation may be induced mechanically by placing devices inside the cervix that will expand while in place. A balloon catheter may be used. Other products include osmotic dilators , such as laminaria stick (made of dried seaweed) or synthetic hygroscopic materials, which expand when placed in a moist environment.
Hegar dilators are used to induce cervical dilation in order to gain entry to the interior of the uterus. During the process of dilation, the cervix may have to be stabilized with a tenaculum , and then the dilators are slowly entered into the cervical canal with a lubricant, starting with a thin, low Hegar number rod and progressing gradually ...
Along with other factors, midwives and doctors use the extent of cervical dilation to assist decision making during childbirth. [34] [35] Generally, the active first stage of labour, when the uterine contractions become strong and regular, [34] begins when the cervical dilation is more than 3–5 cm (1.2–2.0 in).
Dilation and evacuation can be offered for the management of second trimester miscarriage if skilled providers are available. [6] Some women choose D&E over labor induction for a second trimester loss because it can be a scheduled surgical procedure, offering predictability over labor induction, or because they find it emotionally easier than undergoing labor and delivery.
These sounds are intended for probing a woman's uterus through the cervix, to measure the length and direction of the cervical canal and uterus. Dilators are primarily used to open and dilate the cervix to gain access to the uterine cavity, but can also be used as sounds.
Osmotic dilators are most commonly used to slowly dilate and soften the cervix prior to surgical abortion, a process referred to as cervical preparation. Adequate cervical preparation is important prior to surgical abortions because it helps to prevent complications of dilation and evacuation (D&E), such as laceration of the cervix. [ 5 ]
