Cervix assessment for the management of labor induction: Reliability of cervical length and Bishop score determined by residents

Abstract

Bishop score and ultrasound cervical length examination for the management of labor induction are accurate and easy to learn by inexperienced first-year residents. However, cervical length showed higher reliability than the Bishop score.

Cervical condition and fetal cerebral Doppler as determinants of adverse perinatal outcome after labor induction for late‐onset small‐for‐gestational‐age fetuses

“…The rationale for inducing labor at term in late‐onset IUGR neonates is to avoid the infrequent but devastating occurrence of stillbirth, most of which occur with severe growth restriction. However, it could be argued that this policy may increase maternal and fetal morbidity, especially when the cervix is unfavorable.…”

“…The cervical condition was assessed at time of admission using the Bishop score. The Bishop score has been shown to have high reproducibility in our clinical practice. A Bishop score < 2 was defined as a very unfavorable cervix.…”

Design and characterization of a cervical phantom model for birth simulation training

“…A prolonged latent phase of labour may indicate the need for medical intervention, such as administration of oxytocin or performance of a Caesarean section [2], [3]. Similarly, recognition of normal latent labour progression is important for the prevention of unwarranted medical interventions that may increase risk for both the mother and fetus [3], [4]. For example, proper selection of women for the labour induction is important, because induction increases the risk of postpartum and neonatal complications [19].…”

“…For example, a prolonged latent phase of labour may require administration of oxytocin or performance of a Cesarean section [2], [3]. Similarly, accurate diagnosis of normal labour progression is critical for the prevention of unwarranted medical interventions that may increase risk for both the mother and fetus [3], [4]. Clinically, labour progression is diagnosed through observing change in cervical state during consecutive digital vaginal examinations, where the frequency of uterine contractions, dilatation of the cervix and descent of the fetal head are used as key indicators of labour progression [2].…”

Ultrasound Assessment of Foetal Head–Perineum Distance Prior to Induction of Labour as a Predictor of Successful Vaginal Delivery

“…However, not all women get into spontaneous labour and as many as 13-20% require induction of labour for varied indications which include both maternal and foetal causes [1]. Traditionally success of induction is determined by Bishop score, but this score is observer based and significant disagreements have been observed between two resident doctors [2]. This influences the outcome of women chosen for vaginal delivery by induction; many of them end up in operative delivery mainly due to non-progress of labour and foetal distress.…”
