“…Informed consent was taken from the subjects. Prior to induction, a digital examination was performed by the first author (NM) to determine the Bishop's score (Lazanakis et al 2002). Sonographic cervical assessment was performed by one of two trained sonologists within 24 h prior to induction, using a 7.5 MHz transvaginal probe.…”

A total of 100 women with gestational ages of 34-42 weeks requiring induction of labour were consecutively recruited in a prospective study at the Medical College and Hospital, Baroda, India. The aim of this study was to determine the value of transvaginal measurement of cervical length in the prediction of successful vaginal delivery within 24 h. Induction of labour was carried out with Tab Misoprostol (25 microg). A Bishop's score and sonographic cervical assessment were performed prior to induction. Univariate and logistic regression analyses was used. A pre-induction cervical length measurement on TVS was an independent predictor of successful vaginal delivery. At < or =3 cm cervical length, the probability of a LSCS was <30%, while with 4 cm cervical length, the probability became >75%. One unit increase in cervical length increased the probability of LSCS by 45%. The cervical length measurement by TVS is therefore an independent predictor of successful labour induction and performs better than Bishop's score as a method of pre-induction cervical assessment.

“…Although TVU CL is reproducible and easy to learn, 13,14 studies demonstrate conflicting results regarding its predictive accuracy in this clinical scenario. [15][16][17][18][19] The aim of this meta-analysis is to evaluate the accuracy of TVU CL in the prediction of spontaneous onset of labour within 7 days in singleton gestations at term.…”

Background The possibility to predict the delivery date is a question frequently raised by pregnant women. However, a clinician has currently little to predict when a woman at term will deliver.Objective To evaluate the predictive accuracy of transvaginal ultrasound (TVU) cervical length (CL) for spontaneous onset of labour in singleton gestation enrolled at term by a meta-analysis.Search strategy We performed a literature search in electronic databases. Selection criteriaWe included only studies assessing the accuracy of TVU CL in prediction of spontaneous onset of labour in singleton gestations with vertex presentation who were enrolled at term.Data collection and analysis The primary outcome was the accuracy of CL for prediction of spontaneous labour within 7 days. Pooled sensitivities and specificities were calculated.Main results Five studies including 735 singleton gestations were included. For the prediction of spontaneous labour within 7 days for CL <30 mm the pooled sensitivity was 64% and pooled specificity was 60%. The higher the CL, the better the sensitivity; the lower the CL, the better the specificity. A woman with a singleton gestation at term and a TVU CL of 30 mm has a <50% chance of delivering within 7 days, while one with a TVU CL of 10 mm has an over 85% chance of delivery within 7 days.Conclusions TVU CL at term has moderate value in predicting the onset of spontaneous labour. A woman with a TVU CL of 10 mm or less has a high chance of delivering within a week.Tweetable abstract Cervical length at term has moderate value in predicting the onset of spontaneous labour.

“…11 Transvaginal ultrasonography is likely to be more objective and has been shown to have good inter-and intraobserver variability. 12 Several studies have also shown a correlation between Bishop score and transvaginal ultrasonography, [13][14][15][16] whereas others have not. [17][18][19] Overall there has been wide variation in the prediction of success of induction of labor with both the Bishop score and transvaginal ultrasonography.…”
