If the cervix is ligated, the stimulation itself may cause contractions, so if there were contractions before, the contractions may be aggravated after ligation. Therefore, after cervical cerclage, it is important to give positive treatment to stabilize the fetus and use inhibitors of uterine smooth muscle contraction to inhibit uterine smooth muscle contraction, so as to achieve complete stabilization of the fetus in the clinic. In addition, bed rest should be given after cervical cerclage in order to reduce the possibility of contractions to some extent. It is also recommended to have a proper checkup before the operation, so that after the operation, with sufficient rest and treatment to stabilize the fetus, most of them will reach the late stage of pregnancy successfully. After reaching full term, the ligature can be removed and the baby can be delivered by cesarean section or vaginally.
