What are the mechanisms or labour for the baby coming out (active labour)?
descent, flexion internal rotation, restitution external rotation and delivery of the body
What is decention in labour?
The foetus decends into the pelvis this usually occurs after 37 weeks but cna take until labour it is encouraged by increased musclular tone
What is flexion in labour?
The fetus’s head pusehs on the pelvic floor and causes the neck to flex and cases the skull diameter to shrink.
What is internal rotation in labour?
When the baby’s head is pushed against the pelvic floor by contractions and the forward and backward motion allows it to rotate to fit through the pelvis. the ociput is anterior at this stage
What is crowning?
the head no longer retreats after contraction through the vulva
What is extension?
This is when the baby’s head extends onece tit has passed through the vagina and puts pressure on the perineum. This is after its passed through the suprapubic arch.
What is external rotation?
the baby must rotate after head has been born to fit shoulders through the widest part of the vagina
what is restituation/
when the shoulders are aliggned with the head after rotation
