Study Notes

Stage 2 of Labor

Stage 2 begins at full dilatation of the cervix and ends with the expulsion of the baby.

Descent of the Head

The head descends throughout labor.
Flexion of the head produces a smaller diameter of the presenting part, changing the occipito-frontal diameter to suboccipito-pregmatic diameter.

Internal Rotation of the Head

The head rotates as it strikes the pelvic floor.
The occiput moves from its original lateral position towards the pubic symphysis.
Occasionally, the occiput moves posteriorly towards the hollow of the sacrum.

Extension of the Head

The head in flexion descends to the vulva.
The base of the occiput comes into contact with the inferior rami of the pubis.
The head extends until it delivers.

Restitution of the Head

Following delivery, the head rotates back to its original position in relation to the shoulders.

External Rotation of the Shoulders

When the shoulders reach the pelvic floor, they rotate into the antero-posterior position.
