Transvaginal Sonographic Cervical Measurements and Digital Clinical Examination in Predicting Successful Labour Induction
Abstract
ABSTRACTBackground: Induction of labor is safe and effective method of vaginal delivery, however, it carries the risk of cesarean delivery compared with spontaneous labor. Therefore, it is fundamental to assess the cervix condition to predict induction success.
Objective: To assess the value of transvaginal sonograghical cervical measurements in predicting the outcome of labor induction and compare its performance against digital assessment (Bishop score).
Methods: A prospective study in Al-Kadhymia Teaching Hospital, where a group of 90 women with singleton gestation scheduled for induction of labor at more than 37 weeks were studied 48 nullipara and 42 multipara included in the study. Transvaginal sonography measurements of the cervix were performed and Bishop score was determined. All labors were induced by oxytocin infusion and amniotomy.
Results: Successful labor induction occurred in 67(75.5 %) of women, both transvaginal cervical length and Bishop score were independent predictor of successful labor induction.
Conclusion: Transvaginal cervical length can be considered as a diagnostic tool of successful labor induction and it is less subjective than Bishop Score.
Keywords: Induction of labour, Cesarean section, Bishop score, Cervical length.
