Predicting the Outcomes of Labor Induction

preinduction cervical assessment using The Burnett modification of Bishop score with

• Cervical dilatation in centimeters will be given a score of zero if dilatation less than 1cm, a score of 1 if 1-2 cm dilated, a score of 2 if more than 2 cm dilataion.
• Length of the cervix will be given a score of zero if more than 2 cm, a score of 1 if 1-2 cm, a score of 2 if less than 1 cm.
• Station of fetal head will be given a score of zero if -2 or higher , a score of 1 if -1, a score of 2 if zero or lower.
• Consistency of the cervix will be given a score of zero if firm, a score of 1 if soft and a score of 2 if soft and stretchable.
• Position of the cervix will be given a score of zero if posterior, a score of 1 if mid position and a score of 2 if anterior. So, a total score (sum of all scores) of zero at a minimum to 10 at a maximum can be estimated.

and also preinduction cervical assessment using transvaginal ultrasound and Manipal system where:

• Length of the cervix will be given a score of zero if more than 3 cm, a score of 1 if 2-3 cm, a score of 2 if less than 2 cm.
• Length of the funnel will be given a score of zero if absent, a score of 1 if ≤ 0.5 cm, a score of 2 if more than 0.5 cm.
• width of the funnel will be given a score of zero if absent, a score of 1 if ≤ 0.5 cm, a score of 2 if more than 0.5 cm.
• cervical position and shape will be given a score of zero if curved, a score of 2 if straight
• Distance of presenting part to external os will be given a score of zero if more than 3 cm, a score of 1 if 2-3 cm, a score of 2 if less than 2 cm
