What changes in Cervix During Birth Or Labor And Complications?
Cervix Changes During Birth Or Labor And Complications
Cervix Dilation Chart: Stages of Labor
Here are eight cervix changes that occur during birth or labor:
1. Effacement
Effacement refers to the thinning of the cervix as it prepares for delivery. Before labor, the cervix is typically thick and long, measuring around 2-3 cm in length. During the birthing process, hormones signal the cervix to thin out, eventually measuring 100% effaced or paper-thin. Effacement is typically measured in percentages, with 0% indicating a thick cervix and 100% indicating a fully thinned cervix.
2. Dilation
Dilation refers to the opening of the cervix. Before labor, the cervix is typically closed, measuring around 1-2 cm in diameter. As the cervix prepares for delivery, it dilates or opens up. During the active phase of labor, the cervix should dilate around 1 cm per hour until it reaches 10 cm, at which point the baby can pass through the birth canal.
3. Mucus plug release
The cervix is sealed with a mucus plug during pregnancy, which prevents bacteria from entering the uterus. As the cervix begins to efface and dilate, the mucus plug is released. This can happen gradually or all at once, and the plug may be pink, brown, or clear in color.
4. Bloody show
As the cervix begins to efface and dilate, blood vessels can break, causing a small amount of blood to mix with the vaginal discharge. This is known as the bloody show and is an early sign that labor is imminent. It may be accompanied by mild cramping or contractions.
5. Softening
The cervix is typically firm before labor, like the tip of a nose. As the cervix prepares for delivery, it softens, much like the consistency of your earlobe. This allows the cervix to open more easily during labor.
6. Anterior position during pregnancy
The cervix is typically positioned towards the back of the vagina. As the baby moves down towards the pelvis, the cervix rotates towards the front or anterior position. This position makes it easier for the baby to pass through the birth canal during delivery.
7. Rupture of membranes
The amniotic sac holds the baby and the amniotic fluid. During labor, the sac can rupture, which is commonly known as "breaking your water." This can happen naturally or may need to be done by a healthcare provider to help move labor along. Once the sac has ruptured, labor typically progresses more quickly.
8. Cervical lip
The cervical lip refers to the small portion of the cervix that remains undilated during the later stages of labor. It is typically located on one side of the cervix and can prevent the baby's head from descending into the pelvis. In some cases, a healthcare provider may need to gently manipulate the cervix or ask the mother to push in a certain way to help the baby pass through the cervical lip.
It is important to remember that each woman's birthing experience is unique and may not follow a strict timeline.
What are the complications of cervix changes during birth or labor?
Cervical Incompetence
Cervical incompetence is a condition that occurs when the cervix begins to open too early during pregnancy, leading to premature delivery. This condition is often due to a structural weakness in the cervix, which makes it unable to stay closed as the baby grows.
Cervical Tears
During labor, the cervix can become stretched and sometimes tear. This can lead to bleeding and discomfort, and in some cases, the tear may be severe enough to require sutures.
Cervical Stenosis
Cervical stenosis is a condition that occurs when the cervical opening becomes narrow or blocked. This can lead to difficulties in labor and delivery, as the baby may have trouble passing through the cervix. It may require interventions such as cervical dilation or even a c-section.
Cervical Dystocia
Cervical dystocia is a condition that occurs when the cervix does not dilate or open as it should during labor. This can cause prolonged labor and delivery and may require interventions such as medication to stimulate contractions or surgical delivery.
Cervical Cancer
Cervical cancer is a type of cancer that affects the cervix. It is often caused by the human papillomavirus (HPV), a sexually transmitted infection. Women with cervical cancer may experience symptoms such as abnormal vaginal bleeding and pain during sex.
Infection
During labor, the cervix can become infected, leading to a condition known as cervicitis. This can cause discomfort and pain, and may also lead to other complications such as preterm labor and infection in the baby.
Cervical Polyps
Cervical polyps are growths that occur on the cervix. While they are usually benign, they can sometimes cause discomfort and bleeding, especially during labor and delivery. In some cases, they may need to be removed surgically.
Cervical Effacement and Dilation
Effacement and dilation are the two primary cervical changes that occur during labor. Effacement is the thinning of the cervix, while dilation is the opening of the cervix. Complications can arise if these changes occur too quickly or too slowly, leading to difficulties in labor and delivery.
Cervical changes during birth or labor are a natural part of the birthing process, they can sometimes lead to complications that may affect the mother and baby. It is important to work closely with your healthcare provider to monitor any changes and address any complications that may arise to ensure safe and healthy delivery.
