Just immersed in the joy of pregnancy, but in the review was told that the embryo has stopped, sadness is inevitable, but sadness and regret we have to fully understand this enemy, and strive to next time to defeat it. Embryonic arrest refers to a pathological pregnancy in which the embryo stops developing and dies due to defects in the embryo, unfavorable factors in the mother’s environment or the external environment, which is a special kind of spontaneous abortion. Ultrasound manifestations are no fetal buds or incomplete fetal buds in the fetal sac, no fetal heartbeat, etc. Clinical diagnosis mainly relies on ultrasound, combined with blood hCG, clinical symptoms and signs. There are many factors leading to embryonic arrest, including chromosomal abnormalities of the embryo, infectious factors (e.g. TORCH virus infection, mycoplasma infection, chlamydia infection, etc.), endocrine factors (e.g. abnormal thyroid function of the mother, abnormal glucose, luteal insufficiency, etc.), immune factors (e.g. maternal-fetal ABO incompatibility, antiphospholipid syndrome, etc.), coagulation factors (e.g. hypercoagulable state of the mother), as well as maternal Mental factors, environmental factors, etc., but 50% of the embryonic sterilizations have no known cause. The mechanism of embryonic sterilizations is very complex and is caused by a combination of factors. So how to prevent embryonic sterilizations? First of all, adjust your mind, relax, don’t put pressure on yourself, ensure sufficient rest, sleep, develop good living habits, and stay away from the environment that is harmful to your body; secondly, improve the prenatal viral screening (TORCH), vaginal secretion examination, related endocrine, immune, coagulation system and other tests, if there is any abnormality, follow the doctor’s treatment in time, and some of the patients with embryo sterilizations may be on the previous bad Some patients with embryo termination may have undergone embryo chromosome examination for the last adverse pregnancy, if there is an embryo chromosome abnormality, it does not mean that the same abnormality will occur again in the next embryo, if there is a chromosome abnormality in both husband and wife, it is necessary to consult the doctor for the specific abnormality and whether it will affect the next pregnancy. There are many factors and complex mechanisms that lead to embryo termination, there are still 50% of embryo termination with unknown causes, we can’t completely avoid its occurrence, but embryo termination is usually caused by a combination of factors, so don’t lose confidence because of one failure, adjusting your body and mind is the first and the most critical step to success.
