MODEL-med Obstetric Examination Cervix Types

Three Different Cervix Types


Accurately assessing cervical dilatation and fetal presentation is crucial in obstetrics and childbirth for several reasons:

Monitoring Progress of Labor:
Cervical dilatation is a key indicator of the progress of labour. It helps medical practitioners determine how far a woman has progressed through the different stages of labour and if it is proceeding normally. This information allows them to make informed decisions about the timing of interventions or the need for medical assistance.

Predicting the Timing of Birth:
Knowing the cervical dilatation and fetal presentation helps in predicting the timing of birth. It allows healthcare providers to anticipate when the baby is likely to be born, which is essential for proper management of the labour process.

Patient Satisfaction:
For the expectant mother, knowing the progress of labor and the baby’s presentation can provide reassurance and help manage expectations. This can contribute to a more positive birth experience and higher patient satisfaction.

The MODEL-med® Charlie and Charlie’s Mum Obstetric Examination Simulator is designed specifically for medical practitioners to assess cervical dilatation and fetal presentation. The user simply places the cervix over Charlie’s head and then stretches it until the desired dilation is achieved.

In order for our simulator to be true to life, Charlie’s Mum has ischial spines so that the practitioner can assess station, she also comes with three types of cervix.

Primipara Cervix

During childbirth, the term “primipara cervix” refers to the cervix of a woman who is experiencing her first pregnancy and giving birth for the first time.

For first-time mothers (primiparas), cervical dilation can typically take longer compared to subsequent pregnancies (multiparas) since the cervix has not gone through the birthing process before.

Multipara Cervix

The term “multipara cervix” refers to the cervix of a woman who has had multiple previous pregnancies and childbirths.

In women who are multiparas, the cervix may have undergone cervical ripening (the process of softening and thinning) and dilation during previous childbirths. This can lead to some differences in the behaviour of the cervix during subsequent labours compared to first-time mothers (primiparas). For example, the cervix may dilate more efficiently or quickly in some multiparas due to its previous exposure to the birthing process.


Oedematous cervix

During childbirth, an “oedematous cervix” refers to a condition in which the cervix becomes swollen and engorged with excess fluid as a normal part of the physiological changes that occur during labor.

This process is facilitated by hormonal changes and uterine contractions. As the cervix dilates and the baby descends through the birth canal, increased blood flow and changes in cervical tissue can lead to temporary swelling or edema of the cervix.

An oedematous cervix during childbirth is considered a normal response to the labor process. The swelling helps the cervix to soften and dilate, allowing the baby’s head to pass through the birth canal safely.

While edema may be observed in some women, it may not be as pronounced or evident in others.

The progression of labor and the timing of birth depend on multiple factors, including the strength and frequency of contractions, the position of the baby, the mother’s individual anatomy, and previous childbirth experiences.

In summary, accurate assessment of cervical dilatation and fetal presentation is essential for safe and effective management of labour and delivery. It allows healthcare providers to monitor progress, detect complications, and make informed decisions that promote the well-being of both the mother and the baby.
