Abstract:   (1663 Views)
Background and Aim: Prolonged pregnancy is associated with many complications for both mother and fetus. The onset and progression of labor require cervical ripening. This study was performed to evaluate the effect of oral evening primrose capsules on the ripening of the cervix in primiparous women referring to selected centers in Sanandaj, 2020.
Materials and Methods: This study was a single-blind randomized clinical trial That was performed on 80 primiparous women referring to selected centers in Sanandaj in 2020 with a gestational age of 39 weeks to 39 weeks and 6 days. Subjects were randomly assigned to intervention (evening primrose) and control (placebo) groups. The outcome of the study was the ripening of the Cervix which was evaluated for both groups during the period before the intervention, one week after the intervention, and the time of hospitalization. A Bishop scoring table was used to evaluate was ripening of the Cervix. Data analysis was performed using STATA software version 14 and independent t-tests, Fisher's exact test, and Repeated measure ANOA.
Results: Bishop score one week after taking the capsules in the intervention group (3.73±0.90) was not significantly different from the control group (2.88±1.35) (P>0.05), But the bishop score at the time of admission of the intervention group was higher than the control group; The bishop score in the intervention group was 4.56±1.29 and in the control group was 3.13±1.22 and there was a statistically significant difference between the two groups (P=0.005).
Conclusion: the use of oral capsules of evening primrose is effective on bishop score and cervical ripening And it can be used for cervical ripening.
