Main Findings
To the best of our knowledge, this is the largest multi-centre Asian population randomised controlled trial undertaken to evaluate the safety of the DBC as well as the efficacy of the DBC compared to the vaginal prostaglandin. Our findings show that the number of adverse events in hyperstimulation and the use of entonox were significantly less in the women allocated to the DBC group. Our study also showed similar labour outcomes in both groups with regards to recourse to caesarean deliveries. Average time to eventual delivery in both groups was similar.
