Indications
- may reduce perinatal mortality at 40 weeks of gestation[2]
- labor induction at 41 weeks of gestation may be safer than waiting[5]
- often performed at 39 weeks gestation in women of advanced maternal age (> 35 years) in order to lower risk of stillbirth[3]
* success rates for achieving vaginal delivery after induction 70-80%[6]
Procedure
* success rate similar with balloon catheter dilatation vs vaginal prostaglandin[6]
* complications less frequent with balloon catheter dilatation[6]
Complications
- induction of labor doubles risk of amniotic fluid embolism[1]
- does not increase risk of need for Cesarean section[2][3]
- increases risk of admission to neonatal special care unit[2]
- endometritis], severe postpartum hemorrhage[6]
- neonatal respiratory distress; neonatal infection[6]
Notes
- elective induction of labor at 39 weeks
- does not lower risk of neonatal complications or perinatal death[4]
- reduces number of C-sections
