The so-called abortion actually means that the development of embryonic cells is stopped or interrupted for some reason during the differentiation process, which currently accounts for nearly 50% of spontaneous abortions.
According to common sense, it is necessary to terminate pregnancy through induced abortion after abortion, so as not to cause secondary harm to pregnant mother's body. But doctors sometimes don't recommend immediate abortion, which will make pregnant mothers come in a few days. Why?
First, the method of clinical judgment of fetal arrest
In fact, abortion is common in obstetric clinic, and the reasons behind it are extremely complicated, such as chromosome aberration or immature nucleus, environmental problems (drugs, high temperature, radiation, chemical products, noise, etc. ), bacterial infections (rubella virus, cytomegalovirus, mycoplasma, etc. ), as well as some pregnancy diseases (diabetes, hyperthyroidism, etc.
Behind a variety of incentives, doctors' methods of judging abortion are much simpler, and there are two main ways:
1, the actual development of the fetus does not match the gestational age.
Under normal circumstances, the gestational age mentioned by the doctor is calculated according to the last menstruation of the pregnant mother, and on this basis, whether there is abnormality is judged according to the development of the fetus. For example, the normal fetal sac appears in the fifth week of pregnancy, and the fetal heart is in the seventh week of pregnancy. If it does not appear for a long time, the embryo may be aborted.
2. Abnormal ultrasound
Ultrasonic examination is one of the criteria for evaluating fetal development. Under the observation of ultrasound, early embryonic cells can be divided into three parts: fetal sac, fetal yolk sac and embryonic bud. When the ultrasound examination shows the following three abnormalities, it will be judged as fetal arrest:
1, the average diameter of fetal sac is more than 25mm, but the embryo has not been seen for a long time;
2. The embryo does not grow up, but there is no fetal heart beating or the embryo disappears after it becomes fetal heart;
3. gestational sac has not been seen for more than 6 weeks, or gestational sac has been deformed and withered.
Second, why do doctors generally not recommend immediate abortion?
1, inherited from the above, is precisely because there are many reasons for fetal arrest, so we can't simply define the occurrence of fetal arrest according to the above criteria, because the resolution of B-ultrasound is limited, and it is easily disturbed by some external factors, so it is necessary to judge the hormone level of pregnant mothers before making a diagnosis, otherwise it is likely to be misdiagnosed, which will make pregnant mothers miss the fetus in their bellies.
For example, fetal heart can be detected at 7~9 weeks of pregnancy. If not, the following factors need to be further considered and investigated:
For example, whether the fertilized egg is fertilized sooner or later, whether the menstrual cycle of the parturient is normal, the fullness of the parturient's bladder, the accuracy of the inspection instrument, and the examiner's technology will all affect the final inspection result, not necessarily the fetal suspension.
2. Even if B-ultrasound has detected that the embryo is incomplete, there is no fetal heart, and the estrogen and progesterone of pregnant mothers are reduced, all indicators point to fetal arrest, but there may actually be another possibility:
Physicians in the Sui Dynasty once mentioned in Treatise on Febrile Diseases by Stages: "Those who leak cells are called pregnant for several months, and now they have water." In fact, it is said that the fetus may have a further miscarriage. Although the word fetal abortion does not appear in ancient books, there are three stages in this process, namely "fetal leakage", "abnormal fetal wilting" and "stillbirth is not long".
All these mean that the fetus grows slowly in the mother's body, and its life index is weak, which is very close to the edge of death. However, there is still a chance, and perhaps the fetus can be kept alive by placing and raising it.
Therefore, some doctors hold a strict medical attitude and generally do not recommend pregnant mothers to have abortion immediately. They usually suggest to check it again every other day and then give the final advice.
Let's take a look at the real experience of pregnant mothers:
@ Haoshengde: When I was 8 weeks pregnant, I found that the fetus was stopped and had yolk sac, but I couldn't hear the heartbeat of the embryo and fetal heart. I'm ready to give up. As a result, the doctor suggested another examination in a few days. I didn't expect to check the fetus when I went for the second time. God bless me.
