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.
