How to detect ectopic pregnancy in the early stages?

For women, ectopic pregnancy is a very unfortunate thing. It definitely means pregnancy failure. Not only that, ectopic pregnancy can cause great harm to health, such as heavy vaginal bleeding and severe abdominal pain. Therefore, ectopic pregnancy must be discovered and treated in time. The longer the time, the greater the harm. So how to detect ectopic pregnancy in the early stages?

How to detect ectopic pregnancy in the early stages?

It is best to have an ultrasound examination 35 days to 40 days after the last menstrual cycle. If the baby is too small, it cannot be detected by ultrasound. If it is an ectopic pregnancy after 40 days, it may cause bleeding. I hope to get checked out soon and find out that it is not an ectopic pregnancy. The following are the concentrated manifestations of ectopic pregnancy: The interstitial part of the fallopian tube is the part inside the muscular wall that enters the uterine horn. The muscular layer around the lumen is thicker, so the pregnancy can be maintained until about 4 months before rupture occurs. Because this area is rich in blood supply, its rupture is like a uterine rupture, the symptoms are extremely serious, and a large amount of intra-abdominal bleeding often occurs in a short period of time.

If the menstrual cycle is very regular, you can do a urine test within one week to ten days after the menstruation is delayed. It can be detected in the urine. If the urine test is positive, you can do a B-ultrasound examination. It may not be visible very early, so at this time, part of it may be discovered, but some part may not be discovered. If a woman's menstrual cycle is normal, but is delayed or the amount of menstruation becomes less, it is possible that she has an ectopic pregnancy. You can do a urine test as long as there is a change in the menstrual cycle.

During the early examination of ectopic pregnancy, B-ultrasound images may show an enlarged uterus. This image is not the acoustic characteristic of fallopian tube pregnancy, and the possibility of early intrauterine pregnancy with corpus luteum of pregnancy must be ruled out. The use of B-ultrasound to detect the gestational sac and fetal heartbeat is very important for the diagnosis of ectopic pregnancy. With the development of modern medicine, minimally invasive laparoscopic technology can be used to detect ectopic pregnancy and actively treat it, eliminating harm to women.

1. Urine pregnancy test: simple and quick. A positive result can assist in diagnosis, while a negative result needs to be ruled out by quantification of blood β-HCG.

2. Quantification of blood β-HCG: It is an important method for early diagnosis of ectopic pregnancy. In addition to assisting in diagnosis, it can also help determine the activity of the embryo to guide treatment. In ectopic pregnancy, the blood β-HCG level is usually lower than that in normal intrauterine pregnancy. After conservative medical treatment or surgery, monitor blood beta-HCG levels to detect persistent ectopic pregnancy early.

3. Blood progesterone measurement: The progesterone level in patients with ectopic pregnancy is low, which can also be used as an indicator for diagnosing early ectopic pregnancy. The progesterone value in early pregnancy is relatively stable. For example, if the progesterone value is <45nmol/L (15ng/ml) at 8 weeks of pregnancy, it indicates ectopic pregnancy or corpus luteum hypoplasia, with a sensitivity of 95%. There is overlap in the serum progesterone levels of normal and abnormal pregnancy, and it is difficult to determine the absolute critical value between them. It is for reference only. Developed countries include progesterone as a routine monitoring indicator for ectopic pregnancy.

4. Ultrasound examination: Vaginal ultrasound is better than abdominal ultrasound, with an accuracy rate of 70-94% for diagnosing ectopic pregnancy. The diagnosis can be confirmed by seeing a gestational sac ("fallopian tube ring") or fetal heartbeat in the fallopian tube. For those with a history of cesarean section, the anterior wall scar should be observed in particular to avoid missing the diagnosis of scar pregnancy. If the serum β-HCG level exceeds 2000mIU/ml, if it is an intrauterine pregnancy, vaginal ultrasound can detect the gestational sac; otherwise, one should be alert to ectopic pregnancy. Fluid dark areas in the pelvic and abdominal cavities are helpful for diagnosis.
