Cervical cerclage precautions are mainly divided into preoperative preparation and postoperative recovery. The preoperative preparation includes the treatment of existing vaginal inflammation, the adoption of hip-height head-low lying position, postoperative recovery, continuous observation of the condition, the application of uterine relaxants and antibiotics, as well as attention to rest and regular follow-up. Preoperative preparation: If there is vaginal inflammation before the operation, it should be treated first, and make sure that there is no premature rupture of membranes, and the hip-height-head-low lying position should be adopted for 3 to 5 days before the operation. Postoperative recovery: 1. During and after the operation, beta-blockers or magnesium sulfate should be used to suppress contractions. After surgery, bed rest should be observed, uterine relaxants should be continued, and antibiotics should be applied to prevent infection. If the condition is smooth, then the pregnant woman can get out of bed and walk around appropriately after lying in bed for a period of time, but it is not recommended to do too much exercise. 2. Regular follow-up after surgery and early hospitalization. If contractions occur, the sutures should be removed promptly after ineffective treatment, thus avoiding causing cervical tears. Normally, cervical stitches should be removed at 37 to 38 weeks of gestation or before labor. If cervical cerclage is required, the doctor should be consulted in advance about specific precautions to be taken, and the preoperative preparation and recovery should be carried out in accordance with the doctor’s instructions.
