Cervical Ripening, Induction of Labor, Pregnancy
Conditions
Keywords
cervical ripening, misoprostol, supracervical balloon, Foley catheter
Brief summary
Demonstrate that with concomitant and synchronous use of supracervical balloon and vaginal misoprostol for induction of labour, vaginal delivery is achieved in less time compared with vaginal misoprostol alone.
Interventions
Administration of 25 mcg of vaginal misoprostol every 4 hours up to 5 doses
Insertion of a Foley catheter (16French) through the internal os for a maximum of 12 hours
