No fetal heartbeat at 7 months of pregnancy

If the baby loses his fetal heartbeat during pregnancy, it often makes the pregnant mother very anxious and worried. Because when the baby is in the mother's belly, his health condition is also reflected through the fetal heartbeat. Normally, women who are seven months pregnant are ready to welcome the baby. But why does the baby suddenly lose its heartbeat at seven months of pregnancy?

1. What should I do if there is no fetal heartbeat in the seventh month of pregnancy?

The sudden absence of fetal heartbeat during the seventh month of pregnancy indicates that there is something wrong with the fetus and you need to seek medical attention immediately to avoid any accidents to the fetus. Generally, the fetal heartbeat can be seen from B-ultrasound after 7 weeks of pregnancy. If the B-ultrasound examination finds no fetal heartbeat after 8 weeks of pregnancy, the expectant mother does not need to be too nervous and can continue to observe. If there is still no fetal heartbeat after another one or two weeks, it is considered that the fetus is not developing well. It is not a reaction to miscarriage, but it cannot grow into a healthy baby, so abortion is the only choice. If there is no physiological problem, it will not affect pregnancy again.

If there is no fetal heartbeat during the first pregnancy, before trying to get pregnant again, in addition to checking antibodies on both parties to rule out immune factors, bacterial culture should be performed to rule out infection factors if necessary; and chromosome examination of both parties should be performed to rule out genetic and chromosomal causes if necessary. If you get pregnant again, you will need to carry out systematic fetal preservation.

2. What is the reason for no fetal heartbeat in the seventh month of pregnancy?

The absence of fetal heartbeat means embryonic arrest. There are many reasons for embryonic arrest, including genetic factors, infection, exposure to radioactive substances, toxic chemicals, taking drugs that are contraindicated during pregnancy, high temperature, excessive stimulation, etc. In most cases, early embryonic development arrest or miscarriage may be due to problems with the chromosomes themselves.

More than half of the common causes of sudden absence of fetal heartbeat in the seventh month of pregnancy are caused by fetal hypoxia, such as umbilical cord lesions: umbilical cord torsion, umbilical cord prolapse, etc.; fetal factors: malformations, intrauterine growth retardation, infection, multiple births, etc.; maternal lesions: post-term pregnancy, pregnancy-induced hypertension, cardiovascular disease, toxic shock, etc.; placental factors: placental abruption, placenta previa, etc. All of the above reasons will lead to insufficient oxygen supply to the placenta, causing the fetus to die of hypoxia. It is recommended that pregnant women go to the hospital for examination and receive corresponding treatment immediately once they find the disease.
