Abstract

Background: The postdate pregnancy is an obstetric problem . we need to enhance cervical preparation prior to induced labour which is needed to decrease maternal and fetal morbidities .this can be achieved by many ways. The determination of this research stayed to examine the efficiency and protection of using vaginal primrose oil capsules versus intravenous dexamethasone for cervix preparation and induced labor duration in full-term pregnancies.

Materials & Methods: It was a randomized case control study started from November 2023 to June 2024, 84 primiparous females with a gestational age of 40-42 weeks and a Bishop Score of 4 or fewer stood confessed to the obstetrics and Gynecology Department at Al Diwanyiah maternity and children teaching hospital to terminate their pregnancies. The study sample 84 calculated with convidence level 80% and margin of error 5%. Simple random method used to select and divided the sample into three groups, 30 people were given 8 milligrams of intravenous dexamethasone, 29 people were given one evening primrose oil capsule vaginally, and 25 people as a control. All of them were given 6 hours before induction. Then we induce labor with oxytocin and then compare the three groups regarding labour progress and the neonatal outcome.

Results: Results show that after 6 hours of injecting dexamethasone, there is a statistical alteration in the Bishop scoring system among the two groups (5.88±1.18, vs. 5.19±0.85 correspondingly). In the dexamethasone grouping, the time it took to go as of the start of initiation to the start of the vigorous labor stage stayed 90±26.3 minutes, which is shorter than in the controlling group’s 112.88±48.87 minutes. The initial and second stages of labor are completed more quickly in the group of dexamethasone paralleled to the controlling grouping.

Conclusions: Dexamethasone’s administration may contribute more significantly to the process of cervical ripening and labor advancement compared to primrose oil.
