Incidence of 25 week fetal arrest in test tube infants
In vitro fetal arrest at 25 weeks refers to the condition that the fetus dies in the mother's body at about 25 weeks of gestation. Cessation may occur in any pregnancy, but the risk is higher in late pregnancy. However, it is difficult to determine the exact incidence of tire arrest, because the definition and reporting methods of tire arrest vary from region to region and study to study. The following will elaborate on the incidence, predictability, related factors and management methods of tire stoppage.
1. Occurrence rate of tire arrest
The exact incidence of 25 week fetal arrest in IVF infants is not clear because the results of relevant studies vary widely. According to a study on the single pregnancy one pregnant woman children cohort, the abortion rate of IVF is about twice that of ordinary pregnancy. However, this does not mean that the 25 week abortion rate of IVF infants is 2%. Different studies have shown that the incidence of late fetal arrest in IVF is between 0.5% and 5%. This difference may be related to the selection of study samples, fetal development and other environmental factors.
The incidence of fetal arrest is also affected by many other factors, such as the age of the pregnant woman, whether there are other complications during pregnancy, placental health, etc. Therefore, it is not possible to give an exact rate of tire arrest.
2. Predictability of tire stop
The predictability of 25 week fetal arrest in IVF is limited. Although maternal monitoring and regular prenatal examination can provide information about the health of the fetus, they cannot completely predict the occurrence of fetal arrest. In fact, most tire stops occur suddenly without obvious warning.
However, some factors may be related to the increased risk of fetal arrest, such as the high age of pregnant women, chronic diseases such as hypertension or diabetes, fetal abnormalities, etc. Pregnant women may reduce the risk of fetal suspension by maintaining a healthy lifestyle, following the doctor's recommendations for prenatal examination and regular monitoring.
3. Factors related to tire arrest
In addition to the age and health status of pregnant women, the occurrence of fetal arrest may also be related to other factors. These include embryo quality, embryo implantation technology, embryo freezing and thawing process and maternal uterine environment. The risk of fetal arrest in IVF may vary depending on these factors.
In addition, some genetic factors are also related to the occurrence of fetal arrest. A study found that specific gene mutations may increase the risk of fetal arrest in test tube infants. However, these research results need more further research and verification.
4. Management method of tire suspension
Once the IVF is found to have fetal arrest, the doctor will decide the most appropriate management method according to the specific situation. In some cases, doctors may recommend immediate gynecological and obstetric operations, such as intrauterine lavage or laparoscopic surgery, to remove the fetus and placenta to avoid infection and other complications.
For test tube babies over 28 weeks old, doctors may choose to trigger delivery. However, doctors will make decisions based on the specific situation of the pregnant woman and fetus.
summary
The incidence of 25 week fetal arrest in IVF is difficult to determine, but it may be higher than that in normal pregnancy. It is difficult to predict the occurrence of fetal arrest, but some factors may increase the risk of fetal arrest, such as the age of pregnant women, health status and fetal abnormalities. The management method of fetal suspension depends on the specific conditions of the fetus and pregnant women, which may include surgery or induced delivery. However, to reduce the risk of fetal suspension, pregnant women should maintain a good lifestyle and receive regular prenatal examination and monitoring.
