    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.
