Cervical Cerclage to Prevent Preterm Delivery: Before Your Procedure
What is cervical cerclage?
Cervical cerclage (say "SER-vuh-kul ser-KLAZH") is a procedure that helps keep the cervix from opening too soon before delivery.
The cervix is the lower part of the uterus. It leads to the vagina. During pregnancy, it is tightly closed to protect the baby. Normally, it doesn't open until the baby is ready to be born. Most of the time, this happens at 37 to 42 weeks. But sometimes it opens too early.
In cervical cerclage, the doctor sews the cervix shut early in the pregnancy. The stitches are removed in time for the baby to be born.
You may get medicine that makes you unconscious. Or you may get medicine that makes the cervix numb. The procedure will take less than an hour. You may go home the same day.
This procedure can help some high-risk pregnancies last longer. But it also has risks. It can cause infection or miscarriage.
How do you prepare for the procedure?
Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.
Preparing for the procedure
- Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
- Understand exactly what procedure is planned, along with the risks, benefits, and other options.
- If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your procedure. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.) Make sure that you understand exactly what your doctor wants you to do.
- Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
- Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.
What happens on the day of the procedure?
- Follow the instructions exactly about when to stop eating and drinking. If you don't, your procedure may be cancelled. If your doctor told you to take your medicines on the day of the procedure, take them with only a sip of water.
- Take a bath or shower before you come in for your procedure. Do not apply lotions, perfumes, deodorants, or nail polish.
- Take off all jewellery and piercings. And take out contact lenses, if you wear them.
At the hospital or surgery centre
- Bring a picture ID.
- You will be kept comfortable and safe by your anesthesia provider. The anesthesia may make you sleep. Or it may just numb the area being worked on.
- The procedure will take less than an hour.
When should you call your doctor?
- You have questions or concerns.
- You don't understand how to prepare for your procedure.
- You become ill before the procedure (such as fever, flu, or a cold).
- You need to reschedule or have changed your mind about having the procedure.
