Mechanical Methods of Cervical Ripening and Labor InductionGELBER, SHARI MD; SCISCIONE, ANTHONY DOClinical Obstetrics & Gynecology: September 2006 - Volume 49 - Issue 3 - pp 642-657 Symposium on Cervical Ripening and Labor Induction Abstract Author Information This article reviews the safety and efficacy of mechanical agents for cervical ripening. Hygroscopic dilators, balloon catheters, and devices designed for cervical ripening have all been shown to be safe and effective for cervical ripening. Mechanical agents are as efficacious as other agents for cervical ripening. However, there is no method that has been conclusively shown to improve mode of delivery or perinatal outcome. The advantages of preinduction cervical ripening with mechanical devices include low cost, low incidence of systemic side effects, and low risk of uterine hyperstimulation.
