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.
