So it’s no marvel that many individuals affiliate labor progress with one figuring out factor- cervical dilation. Nevertheless, there’s one other key factor to assist resolve when to start out the precise birthing of the baby- station!

What Is Station and Why Does It Matter?

Station refers back to the child’s place in relation to the ischial spines of the birthing individual’s pelvis. The ischial spines are small bony protrusions that may be felt throughout a vaginal exam to evaluate the infant’s descent. (Please resist the urge to examine this your self!)

If the infant’s head has not but descended into the pelvis, it’s measured in destructive numbers from -4 to -1.
As soon as the top is aligned with the ischial spines, it’s at 0 station.
Because the child strikes additional down, it’s measured in constructive numbers from +1 to +4, with +4 indicating crowning.

Understanding the infant’s station will help decide the most effective time to start out pushing, somewhat than relying solely on dilation.

The Fetal Ejection Reflex, Ferguson Reflex and Medicated Births

Some folks expertise an uncontrollable urge to push—one buddy described it as “vomiting out of her vagina”. This highly effective, involuntary physiological response is called fetal ejection reflex coined by French obstetrician Michel Odent.

The Ferguson reflex and the fetal ejection reflex are associated however distinct physiological responses throughout labor:

Ferguson reflex: This can be a neuroendocrine reflex triggered when the infant’s head presses on the cervix and vaginal partitions, stimulating stretch receptors. This strain indicators the discharge of oxytocin, which will increase the power and frequency of contractions. It’s a part of the suggestions loop that helps labor progress.

To assist keep away from pointless interventions, laboring down might be useful. This implies permitting the uterus to proceed contracting and transferring the infant down passively earlier than actively pushing. Because the mom isn’t feeling the complete sensation of contractions in a medicated start, ready till the infant has reached a decrease station earlier than pushing can:

Preserve vitality—no pointless early pushing.
Scale back closing dates imposed by hospital insurance policies.
Enhance the possibilities of a vaginal start by permitting the physique to do the work naturally earlier than participating in energetic pushing.

Key Takeaways

Dilation is simply a part of the labor progress equation—station is equally necessary.
