MD, MSPHClinical Obstetrics & Gynecology: September 2006 - Volume 49 - Issue 3 - pp 585-593 Symposium on Cervical Ripening and Labor Induction Abstract Author Information Criteria for failed labor induction have not been standardized. The increasing prevalence of labor induction and the lack of a definition for failed induction contribute to unnecessary abdominal deliveries. Labor duration, cervical dilation, and uterine activity necessary to attain the active phase are reviewed. A practical definition of failed induction of labor is suggested.
