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

Summary
Brief summary
Induction of labor is a common obstetric procedure that is being more widely used nowadays than ever before. Pharmacologic and mechanical methods are used to induce labor. As there are different modes of action, a reduced
induction-to-delivery time can be expected if the pharmacologic and mechanical methods are used simultaneously. The hypothesis is that a combination of pharmacological (oral misoprostol) and mechanical dilation
(CRB - a double balloon device) improve the efficacy of labor induction. In a primary study the combination showed to be beneficial. These results supposed to be checked in a multicenter trial with different misoprostol regimes.
