Comparison of Bishop score and cervical length measurement through transvaginal ultrasound as prediction against labor induction
Journal Title: Asian Pacific Journal of Reproduction - Year 2018, Vol 7, Issue 6
Abstract
Objective: To compare the Bishop score and cervical length measured by transvaginal ultrasound concerned with prediction over the success of labor induction. Methods: This cross-sectional observational analytical study was conducted from May 2017 to October 2017 at several teaching hospitals of Obstetrics and Gynecology Department, Faculty of Medicine Hasanuddin University of Makassar, India. There were 110 samples of pregnant women undergoing labor induction process including 79 samples of successful induction and 31 samples of induction failure. The data analysis used Pearson Chi-square test and multivariate logistic regression to see the effect of Bishop score and measurement of cervical length with successful induction of labor. Results: Number of samples with successful labor induction with Bishop score <3 was 25 (31.6%) and Bishop score ≥ 3 was 54 (68.4%), with rate ratio=3.714 and P=0.000. With measurement of cervical length (cut-off point 2.98 cm), number of samples with successful labor induction with cervical length≤ 2.98 cm was 12 (15.2%) and cervical length >2.98 cm was 67 (84.8%), with rate ratio=3.124 and P=0.000. Multivahate analysis of logistic regression was found to be more influential in the predicted success of labor induction (P=0.014 with Bishop score <3, odds ratio=1.000 and Bishop score ≥ 3, odds ratio=3.779. Conclusions: Bishop score is better in predicting the success of labor induction compared to the measurement of cervical length through transvaginal ultrasound.
