What tests should be done before threatened abortion?

Spotting during early pregnancy is something that needs to be taken seriously. It is a typical manifestation of threatened abortion. At this time, you need to go to the obstetrics department immediately for medical treatment. Before preserving the fetus, you generally need to undergo relevant examinations to confirm the extent of threatened abortion and the cause of threatened abortion, and develop an accurate plan for preserving the fetus. So, what examinations should be done before preserving the fetus for threatened abortion?

Threatened abortion refers to a small amount of vaginal bleeding before 28 weeks of pregnancy, followed by paroxysmal lower abdominal pain or back pain. Gynecological examination shows that the cervix is ​​not open, the membranes are not ruptured, the products of conception are not discharged, the size of the uterus is consistent with the number of weeks of amenorrhea, and there is hope for the pregnancy to continue. After rest and treatment, if the bleeding stops and the lower abdominal pain disappears, the pregnancy can continue; if the amount of vaginal bleeding increases or the lower abdominal pain worsens, it may develop into inevitable abortion.

The examination of threatened miscarriage includes the following aspects:

1. Medical history inquiry: Ask the patient whether she has a history of recurrent miscarriage, abdominal pain, fever, changes in vaginal discharge, etc.

2. Physical examination: Check body temperature, pulse, respiration, blood pressure, etc.; check whether there is a small amount of vaginal bleeding, slight paroxysmal uterine contractions, whether the cervical opening is dilated, whether the amniotic sac is bulging, and whether the size of the uterus is consistent with the number of weeks of amenorrhea.

3. Auxiliary examination:

(1) Ultrasound examination: Ultrasound examination includes fetal heart beat, gestational sac and fetal movement.

(2) Pregnancy test: Pregnancy test positive.

(3) Progesterone measurement

4. Methods for estimating the prognosis of miscarriage:

(1) If the percentage of keratinized cells in vaginal smear exceeds 30%, the prognosis is generally poor.

(2) Measuring basal body temperature in early pregnancy:

Patients with signs of miscarriage but whose body temperature does not drop have a good prognosis, while those with a lower basal body temperature have a poor prognosis.

(3) Human chorionic gonadotropin (HCG) measurement:

If the level of chorionic gonadotropin decreases gradually, the prognosis is poor.

The above is an introduction to the relevant examinations before preserving the fetus in case of threatened abortion. I hope it will be helpful to you.
