Brief analysis of several common methods of checking ectopic pregnancy

When it comes to ectopic pregnancy, many female friends may find it terrifying. Indeed, severe ectopic pregnancy can cause heavy bleeding and endanger the patient's life. So what are the methods for checking ectopic pregnancy ? The following will tell you about the common methods for checking ectopic pregnancy.

In general, the common methods for checking ectopic pregnancy are:

1. Posterior fornix puncture: Since blood in the abdominal cavity is most likely to accumulate in the rectouterine pouch, even if the amount of blood is small, it can be sucked out through the posterior fornix puncture. Use an 18-gauge long needle to puncture the rectouterine pouch from the posterior fornix of the vagina. If dark red non-coagulated blood is drawn out, it is a positive result, indicating that there is blood accumulation in the abdominal cavity. This is the most common method for checking ectopic pregnancy.

2. Pregnancy test: It is also one of the common methods for checking ectopic pregnancy. When the embryo is alive or the trophoblast is viable, the syncytial cells secrete hCG, and the pregnancy test may be positive. Since the hCG level in patients with ectopic pregnancy is lower than that in normal pregnancy, the general hCG determination method has a low positive rate, and a more sensitive β-hCG radioimmunoassay or monoclonal antibody enzyme-labeled method must be used for detection.

3. Ultrasound diagnosis: In the early stage of tubal pregnancy, B-ultrasound imaging shows that the uterus is enlarged, but the uterine cavity is empty, and there is a low echo area next to the uterus. This is a relatively advanced method for checking ectopic pregnancy. This image is not the sonographic and visual feature of tubal pregnancy, and the possibility of early intrauterine pregnancy with corpus luteum of pregnancy needs to be ruled out. Using ultrasound to detect the gestational sac and fetal heartbeat is very important for diagnosing ectopic pregnancy. If the pregnancy is located outside the uterus, it can be diagnosed as ectopic pregnancy; if the gestational sac is located in the uterus, ectopic pregnancy can be ruled out. B-ultrasound has important clinical significance for early diagnosis of interstitial pregnancy, which can show protrusion of one uterine horn, local thickening of the muscle layer, and obvious gestational sac inside.
