The cervix consists of two parts; the upper part lies in the pelvic/abdominal cavity and the lower part is intravaginal. [1] Cervical effacement or cervical ripening refers to the thinning and shortening of the cervix. This process occurs during labor to prepare the cervix for dilation to allow the fetus to pass through the vagina. While this ...
It is a significant softening of the vaginal portion of the cervix from increased vascularization. This vascularization is a result of hypertrophy and engorgement of the vessels below the growing uterus. This sign occurs at approximately six weeks' gestation. The sign is named after William Goodell (1829–1874).
Prostaglandin E 2 (PGE 2) achieves cervical ripening and softening by stimulating uterine contractions as well as directly acting on the collagenase present in the cervix to soften it. [7] There are currently two formulations of PGE 2 analog available for use in cervical ripening: Prepidil, a vaginal gel, and Cervidil, a vaginal insert. [24]
It pertains to the features of the cervix and the uterine isthmus. It is demonstrated as a softening in the consistency of the uterus, and the uterus and cervix seem to be two separate regions. [1] The sign is usually present from 4–6 weeks [2] until the 12th week of pregnancy. Hegar's sign is more difficult to recognize in multiparous women.
Ladin's sign is a clinical sign of pregnancy in which there is softening in the midline of the uterus anteriorly at the junction of the uterus and cervix. It occurs and is detectable with a manual examination at about 6 weeks' gestation. [1] Ladin's sign is often present during the woman's first pelvic exam when pregnancy is suspected. [2]
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. [2]
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]
This special time period is called "full term". [62] Whenever possible, waiting for labor to begin on its own in this time period is best for the health of the mother and baby. [17] The decision to perform an induction must be made after weighing the risks and benefits, but is safer after 39 weeks. [17] Events after 42 weeks are considered ...
