Transvaginal Ultrasound for Predicting Labor Induction Success

The aim of this chapter is to compare the assessment of the cervix through transvaginal sonography and digital examination in predicting the outcome of labor induction. Digital assessment is limited to measuring the length from the external cervical os to the cervical-vaginal junction, and discomfort associated with this assessment can further affect its accuracy. This prospective observational study was conducted in the Department of Obstetrics and Gynecology at tertiary care centre in New Delhi over a span of 17 months, from November 2009 to March 2011. Regarding the relationship between cervical length and the outcome of labor, women with longer sonographically measured cervical lengths had a decreased chance of vaginal delivery and an increased likelihood of caesarean section. Sonographic cervical length was significantly related to the mode of delivery. The approach, especially in high-risk pregnancies, enhances the prediction of successful labor induction, providing valuable insights for obstetricians and improving the ability to assess outcomes in high-risk cases.
