What Is a Cervical Epidural?

Since Shirodkar and MacDonald described the clinical application of cervical cerclage in 1955, these two types of cervical cerclage, especially MacDonald, have become the most commonly used clinical methods for cervical insufficiency against mid-term pregnancy loss and anti-premature surgery. Research shows that there is a certain preventive effect in high-risk groups, and high-risk groups generally refer to those who have had 3 or more mid-term pregnancy losses or a history of premature birth or accompanied by shortened cervix. The purpose of performing cervical cerclage is to repair and establish normal morphology and function of the internal cervix, so that pregnancy can be maintained to term or the fetus can survive. Surgery is performed more than 14 to 18 weeks of pregnancy.
