The time to do the imaging is within 3 to 7 days after menstruation without intercourse. For patients with irregular menstruation, it can be delayed up to 10 days, and especially irregular patients such as amenorrhea can do it at any time, but the possibility of pregnancy should be excluded. In a very small number of women, there may be a small amount of vaginal bleeding in the first month after pregnancy, so it is important to rule out pregnancy in women with light periods and amenorrhea. Iodine allergy test The medical staff involved in the skin test and imaging must be prepared with emergency drugs in case of sudden allergic reactions during the skin test and imaging. It is important to ensure that one needle and one tube are not disinfected with alcohol and other disinfectants before the skin test, so as not to affect the effect of the skin test. Take 0.1ml of 30% glucosamine for intradermal injection and inject the drug into the lower third of the skin on the palm side of the forearm by puncture. Then push the glucosamine and observe after 15 to 20 minutes to judge the effect of the experiment, then record the results of the skin test in the electronic medical record and prescribe accordingly according to the results of the skin test. Preparation for the tubal angiogram includes: 1. The patient should be clean for 3 to 7 days after menstruation and sexual intercourse is prohibited. 2. Intramuscular injection of atropine 0,5mg can be given half an hour before the procedure to reduce tubal spasm. 3.The patient should empty the bladder. 4. Ask if there is any history of iodine allergy. Half an hour before imaging, perform an iodine allergy test. Generally, perform a skin scratch test by applying 2 or 5% tincture of iodine to the flexural surface of the forearm, about 2-3 cm in diameter, and make a scratch on it, and observe any redness or swelling after 20 minutes. Conjunctival test or venous test can also be done. Conjunctival test (conjunctival drip method): Inject contrast agent into the conjunctiva of one side of the eye and observe whether the conjunctiva is congested, red and swollen after 15 minutes, and compare with the undripped side, if it appears, it is positive. Intravenous test (intravenous injection method): 30% of the same batch number of contrast agent 1ml intravenous injection, 15 minutes later if no reaction is negative, such as the appearance of hives, sneezing, chest tightness, metallic taste in the mouth, laryngeal edema, etc., are positive. Precautions after imaging 1. After imaging, it is forbidden to take a tub bath and have sex for two weeks, and antibiotics can be given to prevent infection as appropriate. 2.Sometimes tubal spasm causes the illusion of tubal incompetence, repeat if necessary. 3. A small amount of vaginal bleeding within one week after the imaging test is normal if there is no other discomfort. 4. It is best to use contraception for three months after imaging to reduce the possible effects of x-ray exposure. However, it has been clinically observed that women who became pregnant in the same month after the imaging did not have an increased risk of fetal abnormalities. The total cost of a trans-x-ray hysterosalpingogram for a patient is usually about $200. There should be special reasons for exceeding this cost. For example, special contrast agents, etc.
