Hysterosalpingography is painful

Hysterosalpingography is a very common gynecological examination. If you feel that you may have a gynecological disease, you should find a way to use this examination method to prevent your condition from being misdiagnosed. However, many female friends will find that hysterosalpingography is very painful. If this is the case, you need to take good care of yourself after the examination and improve your body.

The first step is to dilate the vagina and expose the cervix. The cervix and fornix are disinfected with iohexol, the cervical catheter is filled with iohexol, the air in the tube is removed, the tube is inserted into the cervical canal along the direction of the uterine cavity, and the cervical clamp is tightened so that the conical rubber head of the catheter fits tightly against the cervix to prevent the drug from flowing out.

The second step is that during the hysterosalpingography examination, the patient lies on his back on the X-ray machine operating platform, routinely disinfects the vulva and vagina, then lays a sterile towel, and then checks the position and size of the uterus.

The third step is to observe the contrast agent flowing through the uterine cavity under X-ray fluoroscopy, and slowly inject iodized oil under fluorescent fluoroscopy. The first injection volume is 3-5 ml. Observe its entry into the uterus and flow through the fallopian tubes. At this time, a picture will be taken and then iodized oil will continue to be pushed in. The film will continue after 5-10 minutes.

The fourth step is to take another picture at the same location one day later, and then observe whether there is free iohexol in the abdominal cavity. If both fallopian tubes are blocked, there will be no iodized oil in the pelvic cavity. If there is only a small amount of iohexol, it can be considered that the fallopian tubes are obstructed.

1. The best time for surgery is 3 to 7 days after the patient's menstruation ends. Sexual intercourse is prohibited 5 days before surgery.

2. Atropine 0.5 mg can be injected within half an hour before the operation to reduce fallopian tube spasm.

3. The patient empties his bladder.

5. Ask whether there is a history of iodine allergy. An iodine allergy test is performed half an hour before imaging. Generally, a skin scratch test is performed by applying 2.5% iodine tincture to the flexor surface of the forearm with a diameter of about 2 to 3 cm. A scratch is made on it and the redness or swelling is observed after 20 minutes. Conjunctival testing or venous testing may also be done. Conjunctival test (conjunctival instillation method): Instill contrast agent into the conjunctiva of one eye. After 15 minutes, observe whether the conjunctiva is congested, red and swollen, and compare it with the side without drug instillation. If so, it is positive.

Intravenous test (intravenous injection method): 1 ml of 30% contrast agent of the same batch is injected intravenously. If there is no reaction after 15 minutes, it is negative. If urticaria, sneezing, chest tightness, metallic taste in the mouth, laryngeal edema, etc. occur, it is positive.

5. Patients with constipation can take laxatives orally before surgery to keep the uterus in a normal position and avoid the false impression of external pressure.

Postoperative precautions

1. Do not take a bath or have sexual intercourse for two weeks after angiography. Antibiotics may be given as appropriate to prevent infection.

2. Sometimes tubal spasm may cause the illusion of tubal obstruction. Repeat if necessary.

3. A small amount of vaginal bleeding within one week after the angiography is normal if there is no other discomfort. If the amount of bleeding is more than the menstrual volume or if there are other discomforts, you should contact your doctor.

4. It is best to practice contraception for three months after the contrast examination to reduce the possible effects of X-ray exposure. However, clinical observations have found that women who become pregnant in the same month after angiography do not have an increased risk of fetal abnormalities.
