So what can be done to speed up the process? Is it possible to somehow dilate faster during labor, so that you can hold your new baby sooner? Dilation is a term used for the opening of the cervix. Both dilation and effacement, which refers to the thinning of the cervix, take place to provide an opening from your uterus to the birth canal so that your baby can be delivered. For a vaginal delivery, the cervix needs to be 10 centimeters cm dilated and percent effaced.

- Labor induction — also known as inducing labor — is the stimulation of uterine contractions during pregnancy before labor begins on its own to achieve a vaginal birth.
- The cervix, which is the bottom portion of the uterus, opens when a woman has a baby, through a process called cervical dilation.
NCBI Bookshelf. Kelly C. Wormer ; Ann E. Authors Kelly C. Wormer 1 ; Ann E. Williford 2. In , Edward Bishop set forth criteria for elective induction of labor which included parity, gestational age, fetal presentation, obstetric history, and patient consent as well as a scoring system for the cervix to help predict successful induction of labor.
This pelvic scoring system, widely known as the Bishop score, is still an important determination in the prediction of successful induction of labor. The pelvic score can be ascertained in a patient at the time of induction by a digital cervical exam to determine if cervical ripening is necessary before induction. The Bishop score reflects the normal changes the cervix undergoes in parturition the process of childbirth. Extensive cervical remodeling is needed for the cervix to dilate and pass a fetus fully.
While human parturition is not completely understood, it is a complex system that involves interactions between placental, fetal, and maternal mechanisms.
The nonpregnant cervix extracellular matrix is primarily made up of tightly packed collagen bundles. Gradually throughout the pregnancy the composition of the cervix changes with decreased collagen density and an increase in hyaluronic acid and water content.
The Bishop scoring system is based on a digital cervical exam of a patient with a zero point minimum and 13 point maximum. The scoring system utilizes cervical dilation, position, effacement, consistency of the cervix, and fetal station. Cervical dilation, effacement, and station are scored 0 to 3 points, while cervical position and consistency are scored 0 to 2 points see chart below.
A Bishop score of 8 or greater is considered to be favorable for induction, or the chance of a vaginal delivery with induction is similar to spontaneous labor.
A score of 6 or less is considered to be unfavorable if an induction is indicated cervical ripening agents may be utilized. Avoid digital cervical exams in a patient with placenta previa or before establishing a diagnosis of preterm rupture of membranes. Induction of labor is a commonplace obstetric practice. Predictors for success in induction include many of the similar criteria Bishop set forth in the s. Increasing maternal parity is a strong indicator of the likelihood of successful vaginal delivery and a predictor of shorter length of labor.
Fetal size, gestational age, maternal age, provider patience, and decision to induce versus expectantly manage can be correlated to differing success rates. If a cervix is favorable, induction of labor is likely to result in vaginal delivery, and any method of induction tends to work well.
If a cervix is considered to be unfavorable, no method is highly effective for induction so that patient is a candidate for cervical ripening. Mechanical methods such as a balloon catheter and hygroscopic dilators can be used as well. The score is often performed by a labor and delivery nurse or an obstetrician.

Introduction In , Edward Bishop set forth criteria for elective induction of labor which included parity, gestational age, fetal presentation, obstetric history, and patient consent as well as a scoring system for the cervix to help predict successful induction of labor.
Anatomy The Bishop score reflects the normal changes the cervix undergoes in parturition the process of childbirth. Indications The Bishop scoring system is based on a digital cervical exam of a patient with a zero point minimum and 13 point maximum. Zero percent effacement means the cervix is a normal, pre-labor length.
Fifty percent effaced means the cervix is at half of the expected length. The station is the position of the fetal head relative to the ischial spines of the maternal pelvis.
The ischial spines are halfway between the pelvic inlet and outlet. At zero station, the fetal head is at the level of the ischial spines. Above and below this level are divided into thirds, by which station is denoted with negative numbers above and positive numbers below the zero station. The consistency of the cervix refers to the feel of the cervix on the exam.
A firm cervix has a consistency similar to the tip of the nose, while a soft cervix has a consistency similar to the lips of the oral cavity. Contraindications Avoid digital cervical exams in a patient with placenta previa or before establishing a diagnosis of preterm rupture of membranes.

Dilation of cervix for induction. Nonpharmacologic Cervical Ripening
While your cervix thins and softens, it may also begin to dilate. Your cervix will continue to open throughout labor due to contractions. This is when regular labor contractions will begin to help push your baby out. With regard to your cervix, you may feel a twinge from time to time, but it is entirely possible that you may not feel anything at all.
The only way to know if your cervix is relaxed and dilated is for your doctor or midwife to check. Your cervix is on its own schedule when it comes to relaxation and dilation. All women are different, and it can be difficult to predict when cervical relaxation begins. It can begin at any time—a few weeks before your due date, the night before, or not at all.
Why does that matter? Because your cervix needs to open in order for you to have a vaginal delivery. For the first two 2 hours following insertion, you should remain lying down. If you sit up or walk after the first two hours, you should be careful to ensure the insert remains in place.
The risk is higher in women over age 30, those with complications during pregnancy, and those whose pregnancy has lasted longer than 40 weeks. As you would throughout your pregnancy, be sure to tell your doctor about all prescription or over-the-counter medications you are taking.

New Patient Appointment. Call Us: New Patient Appointment or Your Pregnancy Matters. There are many reasons moms-to-be might be interested in or need induction of labor. Patients might have decided that they:. If your pregnancy is uncomplicated, it is best to wait to go into natural or spontaneous labor. In some situations, induction will be necessary because a complication has arisen that warrants delivery, such as preeclampsia or going significantly past your due date.
Your cervix plays a big role in determining the success of induction of labor. During pregnancy, the cervix usually is firm and stiff enough to help hold the baby in the uterus.
But in the final days or weeks before delivery, the cervix starts to soften and open up. If your cervix is has already started the process of softening and dilating, any method for induction has about an equal chance of success. If your cervix is still closed and firm, it might need some help before induction of labor is started.
During cervical ripening, we can use various methods to start preparing the cervix for contractions. To say that we are mechanically ripening the cervix means that we are forcibly dilating it.
A Foley catheter is typically used to drain urine from the bladder. The tip of the catheter has a balloon, which holds about 2 TBSP of water. If we place the tip of the Foley into the cervix and inflate the balloon, the balloon will push the cervix open over time. Protocols vary, and the bulb will either be left inside the cervix for at least 12 hours or until it falls out.
The cervix can also be dilated just by an examination by your provider. The finger can gently dilate the cervix and separate the membranes from the uterine wall. Medications also can be given to help induce softening and dilatation of the cervix. These medications come in different formulations, and the type you receive typically depends on what your doctor is familiar with and what is available at your delivery hospital.
Misoprostol comes in tablets that can be given by mouth or placed directly against the cervix. The medicine will be absorbed and will start softening your cervix over time. Other common formulations of medical induction agents include endocervical gels and vaginal inserts. However, all of these medications can sometimes trigger too much uterine activity. If your doctor is worried about this, she may choose a mechanical form of cervical ripening. In some protocols for cervical ripening, the mechanical and the medical agents are used simultaneously.
Some studies have shown that using both methods at the same time is safe and can achieve the same result in less time. These patients face an increased risk for uterine rupture. If you do require cervical ripening before your induction of labor, we want you to understand that it is just the first step to having your baby.
During the process, you may sleep some of the time and feel frustrated that not a whole lot is happening. It can be slow-going and pretty boring. If you are a low-risk patient, you might be allowed to have a light meal through the process. We understand that patients and families are in a hurry to get the new baby here! But be patient.
