MEKANISME PERSALINAN NORMAL

Summary

The script explains the stages of labor during childbirth, starting with the engagement of the fetal head into the pelvic inlet. It details the descending process, known as descent or design, and the different head positions: synclitismus, asynclitismus, and posterior asynclitismus. The fetus then undergoes flexion, internal axis rotation, extension, and external axis rotation before final expulsion. Each step in the process is crucial for the fetus to navigate the birth canal, with explanations of the physical movements of the head and shoulders. The process concludes with the complete birth of the baby.

Takeaways

• 😀 The first stage of labor is engagement, where the baby's head enters the upper pelvic door.
• 😀 As the baby's head descends further into the birth canal, this process is called descent or design.
• 😀 When the sagittal suture is aligned with the axis of the birth canal, it’s called synclitismus.
• 😀 Asynclitismus occurs when the fetal head approaches the promontorium, deviating from the optimal alignment.
• 😀 Posterior asynclitismus occurs when the fetal head approaches the symphysis.
• 😀 Flexion (plexi) happens when the chin of the fetus moves towards its chest during descent.
• 😀 During Flexi, contractions push the head further down while it is obstructed by the coccyx.
• 😀 Internal axis rotation happens when the fetal head adjusts to the birth canal to navigate past the coccyx.
• 😀 After internal axis rotation, the fetal head extends, which is the opposite of flexion.
• 😀 Extension occurs when the fetal chin moves away from the chest, preparing for delivery.
• 😀 External axis rotation happens after extension as the shoulder adjusts to the birth canal for final delivery.
• 😀 Exposition occurs when the fetus is entirely born, with the head emerging in a parietal presentation.

Q & A

What is the first stage of the labor process in Indonesia?

The first stage of the labor process is engagement, where the fetal head enters the upper pelvic door.

What does the term 'design' refer to in the labor process?

'Design' refers to the continuous descent of the fetal head during contractions.

What is synclitismus in relation to the fetal head during labor?

Synclitismus occurs when the position of the fetal head is aligned with the birth canal, with the sagittal suture being transverse and parallel to the axis of the birth canal.

What happens during asynclitismus?

Asynclitismus occurs when the fetal head approaches the promontorium, causing the head to tilt to one side.

What is posterior asynclitismus?

Posterior asynclitismus happens when the fetal head approaches the symphysis, causing the head to tilt backward.

What is Flexi in the context of the labor process?

Flexi refers to the position when the baby's chin moves toward the chest, which helps the head navigate through the birth canal.

What role does the coccyx play during the labor process?

The coccyx obstructs the descent of the fetal head, causing an internal axis rotation to help the head adjust to the birth canal.

What happens during internal axis rotation?

Internal axis rotation occurs when the fetal head rotates within the birth canal to align with the passage, helping it move downward.

How does extension differ from Flexi?

Extension is the opposite of Flexi. While Flexi involves the chin approaching the chest, extension occurs when the chin moves away from the chest as the head is pushed out.

What is external axis rotation and why does it happen?

External axis rotation occurs when the fetal shoulders adjust to the birth canal after the head is nearly delivered, helping the body align for final birth.

What is meant by 'exposition' in the labor process?

Exposition is the final stage of labor where the fetus is born completely after completing the necessary rotations and adjustments.

Can you summarize the key steps of the labor process described in the transcript?

The labor process begins with engagement, followed by descent (design), synclitismus, asynclitismus, Flexi, internal axis rotation, extension, external axis rotation, and finally exposition, leading to the birth of the baby.
