Comparison of transvaginal cervical length and modified Bishop’s score as predictors for labor induction in nulliparous women
Journal Title: Asian Pacific Journal of Reproduction - Year 2019, Vol 8, Issue 1
Abstract
Objective: To compare the transvaginal cervical length (TVCL) to the modified Bishop’s score for prediction of successful labor induction in nulliparous women. Methods: A total of 210 nulliparous women who were diagnosed as premature rupture of membranes were recruited in this comparative prospective study, which was carried out in the Obstetrics and Gynecology Department of Ain Shams University, Egypt over two years for labor induction. The studied women were examined by trans-vaginal ultrasound for measurement of the cervical length (CL) and vaginally to calculate the modified Bishop’s score, followed by induction of labor. Collected data were analyzed to compare the TVCL to the modified Bishop’s score for prediction of successful labor induction in nulliparous women. The success of induction process was defined as vaginal birth after the induction of labor. Results: One hundred and forty-three women of studied women had CL <28 mm; 122 of them delivered vaginally (P=0.030). One hundred and forty-six women of studied women had modified Bishop’s score >4; 128 of them delivered vaginally (P=0.006). The CL <28 mm was significantly more specific with more positive predictive value as predictor of successful labor induction compared to modified Bishop’s score. Induction to delivery time was significantly shorter in women with CL <28 mm than women with CL ≥28 mm (P=0.02; 95% confidence interval: 4.9-8.4). In addition, induction to delivery time was significantly shorter in women with Bishop’s score >4 than women with Bishop’s score of ≤4 (P=0.01; 95% confidence interval: 1.6-4.5). Conclusions: Both TVCL and the modified Bishop’s score are complementary tools in pre-induction cervical assessment before induction of labor, while the TVCL at <28 mm is significantly more specific with more positive predictive value as predictor of successful induction than the modified Bishop’s score.
