Abortion cannot be classified as a disease, but many women suffer great physical harm due to abortion, and even develop many diseases, which will also affect the people around them. Many people do not know how to diagnose abortion. So, today we will learn about the diagnostic criteria for abortion.

How to diagnose miscarriage

Diagnosing miscarriage is generally not difficult. Most cases can be diagnosed based on medical history and clinical manifestations, and only a few require auxiliary examinations. After confirming miscarriage, the clinical type of miscarriage should also be determined to decide on the treatment method.

1. Medical history

The patient should be asked whether she has a history of amenorrhea and recurrent miscarriage, whether she has early pregnancy reactions or vaginal bleeding. The amount of vaginal bleeding and its duration, whether she has abdominal pain, and the location, nature and degree of the pain should be asked. It should also be understood whether there is watery vaginal discharge, the color, amount and odor of the vaginal discharge, and whether any products of pregnancy are discharged.

2. Physical examination

Observe the patient's general condition, whether there is anemia, and measure body temperature, blood pressure and pulse, etc. Perform gynecological examination under sterile conditions, pay attention to whether the cervical opening is dilated, whether the amniotic sac is bulging, whether there are products of pregnancy blocking the cervical opening; whether the size of the uterus is consistent with the number of weeks of amenorrhea, whether there is tenderness, etc. Check the bilateral adnexa for lumps, thickening and tenderness. The operation should be gentle during the examination, especially for those suspected of threatened abortion.

3. Auxiliary examination

For those who have difficulty in diagnosis, necessary auxiliary examinations can be used, such as B-type ultrasound imaging: it is currently widely used. It has practical value in differential diagnosis and determination of the type of abortion. For those suspected of threatened abortion, the morphology of the gestational sac, the presence or absence of fetal heart reflexes and fetal movements can be used to determine whether the embryo or fetus is alive, so as to guide the correct treatment method. Incomplete abortion and missed abortion can be confirmed with the help of B-type ultrasound examination.
