between 41 and 42 weeks
which scoring system is used to determine if IOL is likely to be successful?
what score indicates that IOL is likely to be successful?
Bishop score
8 or more = likely successful
5 components of the Bishop score
foetal station cervical position cervical dilatation cervical effacement cervical consistency
common method to help stimulate the cervix and begin the process of labour in patients who are past term
membrane sweep (inserting the finger inside of the cervix)
first line drug for the induction of labour
PV prostaglandin E2 (dinoprostone)
alternative drug that can be used if PV dinoprostone cannot be used
oxytocin infusion
non-pharmaceutical method which helps to induce labour when PV dinoprostone has failed
cervical ripening balloon
