Prerequisites for Induction

As labour approaches, the cervix
normally shows changes known as
‘ripening’ so that it becomes ‘inducible’
and is then called a ‘favourable’ cervix.
The condition of the cervix is the most
important factor in successful induction
and, where ripening has not occurred,
there is a greater chance of a long
labour, fetal hypoxia and operative
delivery.


The Bishop score
This is an accepted method of recording the degree of ripeness before labour (cf. the Apgar Score applied to the newborn baby). It takes account of the length, dilatation and consistency of the cervix and the level of the fetal head. A score of 9 or higher is favourable.
