Conditions

Induction of Labor Affected Fetus / Newborn

Brief summary

Pregnant women at term will be divided randomly into 3 groups: 1. Gynecological evaluation based on classic BISHOP score. 2. Gynecological evaluation based on a modified BISHOP score. 3. Gynecological evaluation based on cervical length as measured by transvaginal sonography. After gynecological evaluation, women will undergo induction of labor based on obstetric evaluation according to the group they were part of.

Detailed description

Women presenting to the obstetric emergency room for follow-up for various obstetric/other medical conditions over 37 weeks' gestation that are candidates for labor induction will receive an explanation regarding the study and sign informed consent. The women will be divided randomly into 3 groups: 1. Gynecological evaluation based on classic BISHOP score. 2. Gynecological evaluation based on a modified BISHOP score. 3. Gynecological evaluation based on cervical length as measured by transvaginal sonography. After gynecological evaluation, women will undergo induction of labor based on obstetric evaluation according to the group they were part of.

Primary

Measure	Time frame	Description
Time to delivery	Up to 72 hours.	The time from induction commencement to delivery of the newborn.

Secondary

Measure	Time frame	Description
BISHOP score after primary induction.	Up to 24 hours.	BISHOP score after primary induction. BISHOP is not an abbreviation and is just the name of the score.
