Definition and cause of tire stop
The third generation of IVF is an assisted reproductive technology. Fetal arrest refers to the termination of embryo development during pregnancy before natural delivery. At present, the specific causes of tire stoppage are not completely clear, but several common factors are considered as possible causes of tire stoppage.
First, chromosomal abnormalities are one of the main causes of fetal arrest. Chromosome abnormalities include numerical, structural and functional abnormalities. Chromosome abnormalities may be caused by gene mutation of parents or mutations during fertilization.
Secondly, the age of the pregnant woman is also one of the factors leading to fetal arrest. The study found that the risk of fetal arrest increases with the age of women. This may be because the quality of eggs decreases with age, resulting in abnormal development of fertilized eggs.
Diagnosis and detection methods of tire arrest
For the diagnosis of fetal arrest, doctors usually make judgments based on the medical history and physical examination results of pregnant women. Common diagnostic methods include ultrasound, blood test and amniocentesis.
Ultrasonic examination is one of the most commonly used detection methods. The doctor will use the ultrasonic probe to observe the condition of the fetus in the uterus, including the heartbeat of the fetus, the size of the fetus and the amount of amniotic fluid. If there is no heartbeat or abnormal size of the fetus, it can usually be judged as fetal arrest.
Blood examination can also be used as one of the auxiliary diagnostic methods for fetal arrest. By detecting the hormone levels in the blood of pregnant women, doctors can understand the condition of the fetus. For example, if the progesterone level is normal, the possibility of fetal arrest may be ruled out.
Determine the time required for tire stall
The time required to determine a tire stall will vary depending on the circumstances. Generally speaking, the doctor will advise pregnant women to carry out multiple examinations after the discovery of fetal arrest to confirm the diagnosis.
Usually, the doctor will advise the pregnant woman to wait for about a week after the termination of pregnancy for re examination. If re examination shows that the embryo is still undeveloped, the doctor may recommend further examination or surgery. This process may take several weeks.
In some serious cases, the doctor may recommend immediate termination of pregnancy to avoid greater harm to the health of pregnant women.
summary
Fetal arrest is a possible complication of the third generation of IVF. The causes of fetal arrest may include chromosome abnormalities and maternal age. Ultrasonography, blood test and other methods are needed to diagnose fetal arrest. The time required to determine the tire stop will vary according to the specific situation, and it usually requires multiple checks to confirm. In different cases, doctors will put forward corresponding treatment suggestions, which may include further examination, surgery or termination of pregnancy. Therefore, for pregnant women who are found to have stopped their pregnancy, they need to actively communicate with their doctors and deal with them according to their suggestions.
