Relationship of bishop score and cervical length by trans-vaginal ultrasound with induction of labor in pregnant lady

This was a prospective study done at Babylon Teaching Hospital, during the period from May to October 2016. To evaluate the role of Bishop score and cervical length in predicting the success of induction of labor, 120 patients who met the inclusion criteria were enrolled in this study. Bishop score and cervical length in millimeters were measured by trans-vaginal ultrasound prior to induction, patients with conditions that contraindicated induction, prostaglandins or vaginal delivery were excluded. Successful induction i.e. delivery within 72 hours after induction was taken as primary outcome in the study. According to the Bishop score and cervical length combination, patients were categorized into 4 subgroups. When Both factors are favorable 90.9% of patients had successful induction, Bishop score was significant predictor of vaginal delivery within 72 hours in nulliparous women only, while cervical length was insignificant predictor. In conclusion, Bishop score when complimented with cervical length by trans-vaginal ultrasound could predict the success of induction of labor
