Induction
The success of labor induction is dependent on the characteristics
of the cervix, commonly referred to as cervical ripeness.
The most commonly used method for assessing the
cervix is the Bishop’s score, where a score F4 is considered
to be unfavorable for labor induction. More recently the
transvaginal US assessment of the cervix has been proposed
as a method for more accurately predicting the success of
induction measured by the risk of cesarean for failed induction
w92, 100x or spontaneous onset of labor w62, 77, 92, 100,
103x.
