Prior to Procedure
You may want to plan for someone to drive you home.
Normally, no medicines are needed for this procedure. However, pain medicines such as
ibuprofen (eg, Advil),
(eg, Aleve), or
(eg, Tylenol) are usually taken. They should be taken about an hour before your appointment. Ask your doctor if this is recommended for you.
Description of Procedure
You will lie on an exam table with your feet in foot rests, as you would for a pelvic exam. A device called a speculum is inserted into the vagina to hold it open. The cryosurgery probe is inserted into the vagina. Nitrous oxide makes the tip extremely cold. The tip is touched to abnormal areas on the cervix. It is held there for a few minutes. You may feel some cramping. The tip is removed. This allows the tissue to return to its normal temperature over the course of 3-5 minutes. This freezing and thawing cycle may be repeated several times for each abnormal area on the cervix.
You will remain lying down for at least ten minutes after the procedure. Some women may feel dizzy and/or flushed after the procedure.
