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.
[35] [36] The second phase of labor begins when the cervix has dilated to 10 cm (4 in), which is regarded as its fullest dilation, [31] and is when active pushing and contractions push the baby along the birth canal leading to the birth of the baby. [34]
The latent phase is defined by cervical dilation of 0 to 6 cm. The active phase is defined by cervical dilation of 6 cm to 10 cm. Second stage of labor starts when the cervix is dilated to 10 cm and finishes with the birth of the baby. This stage is characterized by strong contractions and active pushing by the mother.
In the US, the definition of active labour was changed from 3 to 4 cm, to 5 cm of cervical dilation for multiparous women, mothers who had given birth previously, and at 6 cm for nulliparous women, those who had not given birth before. [45] This was done in an effort to increase the rates of vaginal delivery. [46]
The concern is that performing the dilation too soon before the surgery could increase the risk of preterm birth should the woman ever carry a subsequent pregnancy to term. [ 18 ] [ 19 ] However, for dilation and evacuation at greater than 20 weeks gestation, at least one day of cervical preparation is recommended, with the option of serial ...
Bloody show or show is the passage of a small amount of blood or blood-tinged mucus through the vagina near the end of pregnancy.It is caused by thinning and dilation of the cervix, leading to detachment of the cervical mucus plug that seals the cervix during pregnancy and tearing of small cervical blood vessels, [1] and is one of the signs that labor may be imminent.

Perineal pain after childbirth has immediate and long-term negative effects for women and their babies. These effects can interfere with breastfeeding and the care of the infant. [ 13 ] The pain from injection sites and possible episiotomy is managed by the frequent assessment of the report of pain from the mother.
The absolute risk of such birth-related perinatal loss is comparable to the risk for women having their first birth. [1] Planned VBAC carries an 8/10,000 risk of the child developing hypoxic ischaemic encephalopathy, but the long-term outcome of the infant with HIE is unknown and related to many factors. [1]
