AbstractObjectivesThe aim of this study was to introduce cervical strain elastography to objectively assess the cervical tissue transformation process during induction of labour (IOL) and to evaluate the potential of cervical elastography as a predictor of successful IOL.MethodsA total of 41 patients with full-term pregnancies elected for an IOL were included. Vaginal ultrasound with measurement of cervical length and elastography and assessment of the Bishop Score were performed before and 3 h after IOL. The measured parameters were correlated to the outcome of IOL and the time until delivery.ResultsWe observed an association between the strain pattern and the value of the strain ratio 3 h after IOL and a successful IOL (p=0.0343 and p=0.0342, respectively) which can be well demonstrated by the results after 48 h. In our study population the cervical length and the Bishop Score did not prove to be relevant parameters for the prediction of a successful IOL.ConclusionsWe demonstrated for the first time that the cervical elastography pattern after the first prostaglandine application can help predict the outcome of IOL.

Background: The aim of the study was to find out pre-induction cervical length by TV Sonography, determine Bishops score and to co-relate the obstetric outcome with these two variables.Methods: A study was done on 100 women with singleton pregnancies at 37-42 weeks of gestation, admitted for induction of labour in the Department of Obstetrics and Gynaecology at SGRDIMSR, Vallah, Amritsar, Punjab, India. All women underwent cervical assessment by both transvaginal ultrasound and Bishop Score and the outcome of labour induction was determined.Results: Of the 100 women, 53 women had vaginal delivery and 47 landed into LSCS. Bishop score < 6 and cervical length > 3 cm are cut off values of cervical unfavourablity. Successful induction was achieved among 87.5% and 78% women with favorable cervix according to Bishop Score and Cervical length respectively .Among the 92 and 50 women with unfavourable cervix according to Bishop score and cervical length, 48 (52.17%) and 14 (28%) had vaginal delivery respectively.Conclusions: Hence, cervical length by transvaginal ultrasound is a better predictor for the success of induction of labour as compared with assessment by Bishop Score alone.

A Prospective Study

Background: Induction of labour is one of the common interventions in obstetric practice. Cervical assessment has been used as a prediction of the successful vaginal delivery. This study is designed to investigate transvaginal ultrasonographic cervical measurement as a predictor of duration of labour and successful induction resulting in vaginal delivery and compare the performance of ultrasonographic cervical measurement with that of the Bishop score in predicting the outcome of labour induction.Methods: It is a prospective observational study. In this study, for the 100 primigravida women with gestational age of 37-42 weeks of gestation admitted for induction of labour, the cervical length was measured by transvaginal ultrasound and then Bishop Score was assessed by digital examination. Predictive values for successful labour induction were detected and compared.Results: Using Spearman’s rho correlation both TVS cervical length and Bishop score have significant correlation in predicting the success of induction of labour. Cervical length is the better predictor of the likelihood of delivering vaginally within 24hrs.  In the receiver operating characteristic curves, the best cut-off points for the prediction of successful induction was 26mm for cervical length and 4 for the Bishop Score. However, TVS cervical length appears to be a better predictor than the Bishop Score, with a sensitivity of 58.1% and a specificity of 100% compared to 70.3% and 45.5% respectively.Conclusions: Transvaginal sonographic measurement of cervical length is a better predictor of the likelihood of successful induction of labour within 24hrs of induction and increased vaginal deliveries within 48 hours of induction when compared to Bishop Score.

Background. Induction of labour is not without risk, and it calls for a method that will be sensitive enough to predict successful labour induction. Aim. This study aims to evaluate the role of transvaginal ultrasonographic cervical length measurement at term in the prediction of successful induction of labour (IOL). Materials and Methods. This prospective study was carried out in the Department of Obstetrics and Gynaecology of Federal Teaching Hospital Abakaliki between 1st of July and 30th of November 2015. Preinduction Bishop score and cervical length were assessed before induction of labour. Intracervical, cervical, extraamniotic Foley catheter was used to improve the Bishop score. The data were analyzed using the IBM SPSS Statistics 20. Results. The mean maternal age of the study group was 30.68 ± 6.38 years with a range of 19–43 years. The mean gestational age and parity were 39.57 ± 1.49 and 1.85 ± 0.63, respectively. All the women studied had successful induction of labour with mean induction delivery time of 8.1 ± 3.0 hours and mean duration of labour of 7.4 ± 2.9 hours. Preinduction cervical length is a good predictor of a short duration of labour (P=0.001). Parturient with a preinduction cervical length of less than 3 cm was likely to have labour lasting less than 6 hours (RR = 4.20 (95% CI 1.85–9.529). Conclusion. Transvaginal sonographic measurement of cervical length provides a useful prediction of the likelihood of duration of labour following the induction of labour. It is recommended that IOL should be considered and success anticipated in a parturient with a cervical length less than 3 cm.

Background: Induction of labour implies stimulation of uterine contraction before spontaneous onset of labour with or without ruptured membranes. Aim of this study was to compare the efficacy and safety of intracervical Foley’s catheter with oxytocin and vaginal misoprostol for labour induction at term.Methods: A total 100 term pregnant women were chosen with bishop score <6 and divided into two groups: Foley’s catheter with oxytocin (Group A) and vaginal misoprostol (Group B). In Group A, a 16 F Foley’s catheter introduced beyond internal os and traction applied every 4 hourly to check for expulsion with simultaneous oxytocin infusion (2 mU/min up to 32 mU/min). In Group B, 25 mcg misoprostol administered every 4 hourly (maximum 6 doses or 150 mcg). Data analysed using SPSS software 20.0. A p value <0.05 was considered statistically significant.Results: No statistical difference found between demographic variables between two groups. Both primigravida and multigravida had poor pre-induction bishop score in both groups. Foley’s catheter (80%) and misoprostol group (96%) had successful induction and was statistically significant (p<0.05). Foley’s catheter took more time from induction-delivery both in primigravida and post-dated pregnant women. The rate of cesarean in Foley’s catheter group was high (62.5%) including 33% cases with failed induction. Foley’s catheter had less maternal and neonatal complications, less NICU admission as compared to misoprostol (p>0.05).Conclusions: Misoprostol was found better for successful induction, decreases induction-to-delivery interval and increases vaginal delivery as compared to Foley’s catheter but it needs constant supervision in view of hyperstimulation and tachysystole.

Background: The current study aims to compare the efficacy of Bishop score assessment and transvaginal ultrasonographic measurement of the cervical length in prediction of the outcome of labor induction in post-term pregnancy.Methods: A comparative Prospective observational study conducted in Department of Obstetrics and Gynecology, Kom Ombo central hospital from January 2017 to October 2017. Pregnant women were classified into two groups of Bishop Score Group (1): ladies with (Bishop Score <5) = unfavorable cervix and Group (2): those with (Bishop Score >5) = favorable cervix. Also, they were classified into two groups of cervical lengths: Group (1): women with (cervical length <25mm, shorter cervix) and Group (2): those with (cervical length ≥25 mm, longer cervix). The Primary outcome was Bishop score by digital examination and Cervical length by TVS.Results: The study group was 100 women. Regarding sonographic assessment, 44 patients had cervical length <25 mm and the mean cervical length for the whole study group was 25.19±8.16 mm. Successful induction was achieved in 78 patients (78%), while CS was done in 22 patients due to failed induction.  No difference between both groups regarding the parity (p=0.063). When comparing women with successful VD versus those delivered by CS, we found significantly higher Bishop score in the first group 5.12 ± 1.93  vs 3.89 ± 1.71 in the second group (p=0.002). Additionally, VD group had significantly shorter cervix than CS group (22.31 ±7.14 vs. 35.37± 5.80 mm, p=0.007). The Bishop score showed significant moderate negative correlation with the cervical length (r=-0.589, p=0.001).Conclusions: Success of labor induction in women undergoing induction due to prolonged pregnancy can be highly predicted by cervical length as it is more objective and accurate than Bishop Score. The 25 mm cut-off point for cervical length was the best predictor of vaginal delivery.

Background: PGE2 gel (cerviprime) not only helps in cervical ripening but also sensitizes the uterine musculature to physiological PGE2 for generation and maintenance of uterine contractions. In the present study the efficacy of PGE2 intracerival gel for ripening and induction of labour has been reported.Methods: This is a randomized prospective study of 80 cases admitted to the labour room during period of 2 years i.e. March 2017 to March 2019 in Department of Obstetrics and Gynecology, KBNIMS, Gulbarga, Karnataka. All patients had clear indications for termination of pregnancy. The initial bishop score determined prior to induction by pelvic examination. Under aseptic precautions PGE2 endocervical gel was instilled. The results analyzed for successful ripening, induction delivery interval, results in primigravida and multigravida with single instillation or reinstallation if required, mode of delivery and maternal and perinatal complications.Results: The present study of 80 cases showed that a single application of intracervical PGE2 gel caused favorable changes in cervix by increasing Bishop score and shortened induction delivery interval with minimal side effects. Successful ripening with single application was achieved in 92.5% of cases (primi 42.5% and multi 50%). Only 6.25% of primi's and 1.25% of multi’s required reinstallation of PGE2 gel. Successful induction was achieved in 47.5% primi's and 50% multi’s i.e. 97.5% cases.Conclusions: The study concludes that single low dose intracervical PGE2 (cerviprime) gel proved to a safe, reliable and effective method for cervical ripening and induction of labour.
