After fetal growth restriction occurs, it is still necessary to send the fetus for examination after dealing with any abnormalities that arise. There are many factors that can cause embryonic arrest, such as maternal factors, abnormal immune function, and the environment of the pregnant woman. More importantly, factors related to the embryo, such as chromosomal abnormalities in the embryo, are the main cause of embryonic arrest. Therefore, after embryonic arrest occurs, it is recommended to go to the hospital for a fetal chromosomal examination to lay a good foundation for the next conception.

Is hospitalization necessary for embryonic arrest?

This is not necessarily the case; it depends on the specific situation. Firstly, we need to consider the timing of the embryo arrest. If the embryo arrest occurs within 70 days of pregnancy, generally, hospitalization is not needed, and a miscarriage can often be handled on an outpatient basis. However, if the embryo stops developing after 70 days of pregnancy, even reaching three or four months, then hospitalization is required for a induced labor. This is because the fetus is relatively larger, making outpatient treatment problematic and riskier. Additionally, we must also consider if the pregnant woman has any complications. If there are complications alongside the embryo arrest, it is generally safer to be hospitalized.

How to handle bleeding due to embryonic arrest?

If it has already been determined that the embryo has ceased to develop and significant vaginal bleeding has occurred, it is likely that the bleeding is caused by uterine contractions stimulated by the halted embryonic development. In this case, it is first necessary to seek medical attention promptly. After confirming the halted development of the embryo, it is important to perform a surgical abortion promptly to completely remove all tissues associated with the ceased embryonic development, reducing the occurrence of post-abortion bleeding. After the surgery, it is also necessary to promptly use antibiotics to prevent infections within the uterine cavity.

Can traditional Chinese medicine be used to regulate embryonic arrest?

After experiencing a case of embryonic arrest, it is crucial to actively investigate the cause, and it is not feasible to rely solely on drinking herbal medicine for treatment. The causes of embryonic arrest can include genetic factors, endocrine factors, immunological factors, infectious factors, and abnormal uterine conditions in women that may also impact embryonic development. However, if the cause is not identified, there is still a possibility of another embryonic arrest in the next pregnancy. Therefore, consuming herbal medicine is insufficient for treatment, and it is necessary to go to the hospital for a detailed examination. After determining the cause, treatment can then proceed.

Does an embryonic arrest require a uterine curettage?

After discovering that the embryo has ceased developing, it is necessary to undergo a uterine cleaning treatment. If an embryo arrest is not dealt with promptly, it can cause an infection in the uterine cavity and even lead to abnormalities in the woman's coagulation function, which is very detrimental to health. However, a uterine cleaning is not always necessary. If the gestational sac is relatively small, medications can be used to induce contractions of the uterus, facilitating the expulsion of the gestational sac from the body. It is advisable to handle the situation promptly after discovering an arrested embryo and to perform thorough prenatal screenings before attempting to conceive again, to prevent the recurrence of such adverse pregnancy conditions.

Can an arrested embryo be expelled naturally?

Embryonic arrest, also known as missed miscarriage, refers to the restriction of growth and development of the gestational sac in early pregnancy due to various factors, with no fetal heartbeat detected on an ultrasound at 9 weeks of pregnancy. When embryonic arrest occurs, a natural miscarriage may happen, but it's also possible that a natural miscarriage won't occur. Once embryonic arrest is confirmed, waiting for a natural miscarriage isn't advisable, as it is unpredictable and sometimes there might be no signs of miscarriage for a long time. Unrestricted waiting in such cases can harm a woman's body. Therefore, once embryonic arrest is diagnosed, hospitalization should be promptly sought, and artificial intervention methods such as surgical or medical abortion should be considered. While there is a possibility that the embryo could be expelled naturally, the likelihood is relatively low.
