A protruding amniotic sac at 23 weeks of pregnancy is generally considered to be caused by cervical insufficiency and requires bed rest, medication and placement of a uterine support. 1. Bed rest: Pregnant women need to pay attention to adequate bed rest and reduce activities, which can help reduce the incidence of miscarriage and preterm labor. 2. Medication: In order to avoid inducing miscarriage or preterm labor, it is necessary to consider applying luteinizing hormone vaginal preparations and contraction inhibitors, such as oral dextroprogesterone and ritodrine hydrochloride tablets, to reduce contractions and prevent premature rupture of membranes. 3. Placement of uterine support: As the cervical opening is too loose, it is easy to induce miscarriage or preterm labor, so it is necessary to place a uterine support through the cervix to play a certain therapeutic effect. All of the above drugs have certain risks, patients need to use under the guidance of a doctor.
