If a clear diagnosis of fetal arrest has been made, it is recommended that it be cleared up in a timely manner, as there is no cure for fetal arrest. The longer it stays in the womb after fetal arrest the more harmful it is to the pregnant woman’s body. However, it also depends on the personal wishes of the pregnant woman. Many times pregnant women are unable to accept the situation, but they should face the reality and go to the hospital in time to receive treatment to avoid hemorrhage from occurring and thus causing life-threatening injuries. Fetal termination can occur after the pregnancy is terminated, and the way to terminate the pregnancy depends on the length of the gestation period and the size of the fetal sac. If the gestational period is long and the sac is large, a medical abortion may be recommended, as it is more difficult to scrape the uterus. If the auditory time is too long, it may lead to coagulation dysfunction, resulting in severe bleeding, and hospitalization is recommended. Before the abortion, check the blood routine, coagulation function, and prepare for blood transfusion. During oral medication, heavy vaginal bleeding may occur at any time. If coagulation dysfunction occurs, fresh blood, plasma and fibrinogen should be transfused as early as possible, and the uterus should be cleared after the coagulation function improves. There are many reasons why the embryo stops developing, for example, the embryo itself is not well developed and usually dies naturally, there are deaths caused by hormones that are not enough to support the development of the embryo, or malformations of the uterine cavity that prevent the embryo from growing. Pregnant women smoking, drinking, environmental pollution, exposure to radioactivity or taking prohibited drugs; or sexual intercourse is not restrained and sexually transmitted diseases, etc., as well as chromosomal variations in one of the spouses, husband and wife blood type incompatibility, hormone secretion, endometrial thinning, sperm abnormality, immune antibodies, etc. These conditions are prone to lead to embryonic arrest, if the pregnancy should be promptly to the hospital for examination, and should be on time to do the pregnancy test. If you are pregnant, you should go to the hospital in time for examination and take pregnancy tests on time.
