Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Combination of OM and mechanical dilation with a double-balloon catheter for cervical ripening (COOK CRB) is used.

Each participating hospital uses its own misoprostol regime plus CRB for a maximum of 12 hours the first day.

e.g. the regime of the primary study unit:
First day: OM 50 microg with repeat doses 4 and 8 hours later if necessary plus CRB for a maximum of 12 hours
Second day: OM 100 microg with repeat doses 4 and 8 hours later if necessary
Third day: misoprostol 50 microg vaginally with repeat doses 4 and 8 hours later if necessary

Comparator / control treatment
Only the misoprostol regime.

e.g. the regime of the primary study unit:
First day: OM 50 microg with repeat doses 4 and 8 hours
later if necessary
Second day: OM 100 microg with repeat doses 4 and 8 hours later if necessary
Third day: misoprostol 50 microg vaginally with repeat doses 4 and 8 hours later if necessary
