Cervical cerclage time

The cervical cerclage operation still has a certain time limit, and many people are still unaware of this issue, so it will cause various sequelae to their bodies, especially for some female friends who are already physically weak, which will cause more serious consequences. If sequelae appear, they will probably need to stay in bed for a week or two before they can fully recover, and they cannot overwork.

1. Carefully perform a vaginal examination to understand the length of the cervix and the location of the internal opening. The cervix is ​​exposed after routine disinfection. Use rat-tooth forceps or oval forceps to clamp the upper lip of the cervix and pull it downward. Use a vaginal retractor to push the vaginal mucosa and bladder upward.

2. Use a triangular needle to pass nylon thread or No. 10 silk thread around the cervix near the internal os, starting from the anterior wall of the cervix at 10-11 o'clock, and penetrate into the cervical muscle layer. After removing the needle, continue to make circular sutures at 7-8 o'clock, 5-4 o'clock, and 2-1 o'clock on the cervix, that is, pass 4 needles around the cervix. Remove the needle from the cervix at 1 o'clock, tighten both ends of the suture, tie a knot at the anterior fornix after tightening, and leave 3 cm of the tail to facilitate suture removal.

The following treatments are done after cervical suture surgery:

1. Rest in bed for 1 to 2 weeks, continue intramuscular injection of progesterone, and take oral sedatives to maintain pregnancy. Antibiotics are used selectively to prevent infection.

2. Regular check-ups and follow-ups. The cervical sutures were removed at 38-39 weeks of pregnancy, and the patient was admitted to the hospital one week before the expected date of delivery.

3. If symptoms of miscarriage or premature birth occur after suturing, the sutures should be removed promptly to avoid cervical laceration.

1. The suture depth of the cervical tissue should be appropriate and should not penetrate the mucosa too deeply. Also don't wear it too shallowly to avoid the seams slipping off.

2. Tighten both ends of the suture, and use the tip of one hand's index finger to enter the cervical canal, and then tie it to prevent the cervical canal from being too loose or closed after ligation.

3. During pregnancy, the cervix becomes congested and prone to bleeding, and the uterus becomes easily irritated, so the operation should be gentle.

1. Carefully check whether there are suitable indications for circumferential suturing.

2. Surgery during pregnancy can easily cause bleeding and miscarriage. Therefore, medication to preserve the fetus should be used 3 to 5 days before surgery, such as intramuscular injection of progesterone 20 to 30 mg/d and oral sedatives. Inject 0.1g of phenobarbital sodium half an hour before the operation. The best time for surgery is between 14 and 18 weeks of pregnancy.

3. For non-pregnant women, surgery should be performed 3 to 7 days after the end of menstruation. If there is acute inflammation of the vagina and cervix, treatment should be given first and surgery should be performed after recovery.

4. For suture selection, nylon thread, No. 10 double silk thread or cotton thread can be used for those with a higher gestational age, because cotton thread is astringent and the ligature is not likely to slip off. No. 10 monofilament thread is used for small gestational age or purse-string suture.
