Role of Preinduction Transvaginal Ultrasound Measurment of Cervical Length in Prediction of Labour Induction Success

Abstract Background: A common intervention in contemporary labor is induction of labor. Since its introduction in 1964, the Bishop score has been the gold standard for determining favorability for induction of labor. However, the Bishop score's assessment of the cervix's "favorability" prior to induction is very subjective, and several studies have shown that it has a poor prognostic value, particularly for women with low Bishop scores. Aim of Study: Was to assess the accuracy of transvaginal and other ultrasound parameters in predicting the outcome of labor induction. Patient and Method: Transvaginal ultrasonography was used to evaluate cervical length. In our research, 100 pregnant women between 37 and 42 weeks had labor induction. A digital cervical examination and Bishop score were recorded before to induction. Results: A statistically substantial negative link between Bishop Score and failure of induction and chance of C.S. and a statistically substantial positive connection between cervical length as evaluated by ultrasonography and those two out-comes. Conclusion: In this study we found that Bishop score and ultrasonographic cervical length both have a strong correlation with effective induction. The Bishop score does not appear to be as accurate as cervical length measured by ultrasonog-raphy in predicting successful vaginal delivery within 24 hours. The cutoff value for cervical length is 2.8cm, and cervical length has higher sensitivity, specificity, and diagnostic accuracy than bishop score.
