5
Q
What is the score used for predicting whether induction of labor will be required?
A
Bishop’s score - higher is most likely to achieve a successful induction.
> 7 considered favourable for amniotomy.
<5 means cervical ripening agents need to be used.
6
Q
What are examples of cervical ripening agents?
A
- Prostaglandins - misoprostol, pessary/vaginal gel
- Cervical balloon - good cos less likely to cause foetal distress
- Oxytocin - beware uterine hypertonicity. CTG monitoring
