Univariate analysis showed that the following factors influenced the outcome of vaginal delivery achieved within 24 hours, namely parity, hypertension, rupture of membranes, oligohydramnios with intact membranes, suspicious CTG and Bishop score
The early and late epidural groups did not differ significantly by age, BMI, gestational age, birth weight, reason for induction of labor, or the proportions of women who were nulliparous or who had a Bishop score
greater than 5 at admission.
Among women in the study group, those with a Bishop score
greater than 6--considered a favorable cervix--had a 4% cesarean rate, compared with 19% for women who had a Bishop score
of 6 or less, which was a significant difference.
An improved Bishop score
before induction increases the rate of vaginal birth.
An audit form was attached to the front of the chart of every patient who presented to the labor and delivery unit for induction, and information such as gestational age, stated reasons for induction, attending physician, parity, Bishop score
, and delivery outcomes was tracked.
In both groups, the median age was 25 years, the initial Bishop score
was 2, and the Bishop score
at induction was 8.
A Bishop score
was determined at baseline, at the time of each subsequent gel treatment, and at the time when the Foley catheter was expelled.
Then their cervix is checked and their Bishop score
is recorded before they receive a single oral 50-[micro]g tablet of misoprostol.
