1.Vaginal bleeding after contrast: There is often vaginal bleeding for no more than 3-5 days after contrast, which is related to intraoperative cervical canal injury. To prevent infection, so prophylactic antibiotics are usually required for 3-5 days after the imaging procedure. If vaginal bleeding exceeds five days you are advised to consult a doctor. 2. Post-imaging vagal hyperactivity problem: Individuals may have vagal hyperactivity problem after imaging, which is manifested as cold sweat, dizziness, weakness, nausea, vomiting, panic and other deficiency symptoms, bradycardia and other related symptoms. These people who normally squat and suddenly get up often experience dizziness and black eyes, which are related to their vagus nerve underdevelopment. For this group of people, it is recommended to give vagus nerve inhibiting drug-atropine injection before imaging, which can greatly reduce or avoid its attack. These people are often sensitive to pain and often have tubal spasms, so it is also recommended to give atropine to prevent dysmenorrhea before imaging. 3. Post-imaging contraception: contraception is recommended until after the onset of menstruation. 4. Chronic pelvic inflammatory disease after contrast: Although rare, contrast does have the potential to cause acute attacks of chronic pelvic inflammatory disease! Especially for patients with weak resistance. Therefore, for patients who have abdominal pain that is still not significantly relieved or has a tendency to worsen three days after contrast surgery, we recommend prompt consultation.
