Introduction
Fetal arrest at 9 weeks typically refers to the phenomenon of fetal demise occurring at 9 weeks of pregnancy. The main causes include maternal age, chromosomal abnormalities, infections, diabetes, hypertension, and others. It is recommended that pregnant women maintain a relaxed mindset in daily life. After experiencing fetal arrest, they should avoid excessive anxiety, actively regulate their physical health, maintain emotional well-being, and follow a healthy diet to ensure balanced nutrition.

Under normal circumstances, the main causes of fetal arrest at 9 weeks of gestation include advanced maternal age, chromosomal abnormalities, infections, diabetes, and hypertension. Pregnant women are advised to seek timely medical treatment. Specific analysis is as follows:

1. Age: If a pregnant woman is of advanced maternal age, her bodily functions gradually decline, which may increase the risk of fetal arrest. It is recommended that women try to conceive before the age of 30 to avoid adverse effects on fetal development due to increasing age.

2. Chromosomal abnormalities: Chromosomal abnormalities in the embryo may often lead to cessation of embryonic development. It is recommended that pregnant women promptly go to the hospital to terminate the pregnancy. Medications such as mifepristone tablets and misoprostol tablets may be taken under medical guidance. Additionally, both partners should undergo chromosomal testing.

3. Infection: If a pregnant woman does not take proper daily precautions during pregnancy and becomes infected with a virus, the infection may pass through the placenta into the fetus, potentially causing fetal arrest. Pregnant women should take protective measures, avoid crowded places as much as possible, and prevent infections.

4. Diabetes: If a pregnant woman has pre-existing diabetes and fails to control her blood sugar levels in time, elevated glucose levels can impair fetal development and lead to fetal arrest. It is recommended that women manage their blood sugar before conception. Medications such as acarbose tablets, metformin hydrochloride tablets, and glibenclamide tablets may be used under medical supervision.

5. Hypertension: If a pregnant woman has pre-existing hypertension, persistently elevated blood pressure may cause fetal ischemia and hypoxia, thereby affecting normal fetal development and leading to fetal arrest. Pregnant women should monitor and control their blood pressure. Medications such as metoprolol tartrate tablets, nifedipine tablets, and nimodipine tablets may be taken under medical guidance.

Pregnant women should maintain a relaxed mindset. After experiencing fetal arrest, they should avoid excessive anxiety, actively recover physically, maintain emotional well-being, and follow a healthy, nutritionally balanced diet.

Can you eat purslane during early pregnancy?
Under normal circumstances, purslane should not be consumed during early pregnancy. The specific reasons are as follows: Purslane is considered a cold-natured herb that may irritate the spleen and stomach. Pregnant women who consume purslane may experience diarrhea. Accelerated intestinal motility can exert pressure on the uterus, potentially leading to fetal skeletal malformations or even fetal demise due to insufficient oxygen supply.

How long after fetal demise does the uterus become infected?
There is no fixed timeframe for uterine infection following fetal demise; the key factor is the timely expulsion of embryonic tissue. If the embryonic tissue is naturally or artificially expelled within a short period, the risk of infection is low. However, if the tissue remains in the uterus for more than two weeks, the likelihood of infection significantly increases, warranting special vigilance. It is important to closely monitor vaginal bleeding and the odor of vaginal discharge in daily life, and seek prompt medical attention if any abnormalities are detected.

What are the causes of single fetal demise in twin pregnancies?
Under normal circumstances, the cessation of development in one of twins may be caused by factors such as developmental differences between the embryos, unequal placental allocation, chromosomal abnormalities, gestational hypertension, or chorioamnionitis. If discomfort symptoms occur, it is recommended to seek timely medical consultation and treatment at a正规 hospital. In daily life, pregnant women carrying twins should pay extra attention to rest and avoid strenuous activities.

Is facial numbness in the late stages of pregnancy a sign of fetal demise?
In general, facial numbness in the late stages of pregnancy is not necessarily an indication of fetal demise. Whether facial numbness during late pregnancy suggests that the fetus has stopped developing needs to be determined based on specific circumstances. As the fetus grows and the uterus expands, pressure may be placed on the veins, affecting blood supply to the head and causing facial numbness. This is generally considered a normal phenomenon and is not directly associated with fetal demise.

Can a transvaginal ultrasound confirm a missed miscarriage?
Transvaginal B-mode ultrasound examination has high accuracy in diagnosing fetal demise. If, during the ultrasound examination, the physician observes no fetal heartbeat or discrepancies between fetal size and gestational age, and if these findings are consistent across multiple consecutive examinations, transvaginal B-mode ultrasound can serve as one of the bases for diagnosing fetal demise. However, specific diagnosis must be comprehensively determined according to the stage of pregnancy and results of other examinations.

Can retained fetal products after fetal demise affect coagulation function?
Under normal circumstances, retained fetal tissue after fetal demise may affect coagulation function. If necessary, it is recommended to consult a physician. When the fetus stops developing and remains in the uterine cavity without timely intervention, the placenta may begin to dissolve. During this process, an enzyme called fibrinolytic enzyme may be released into the maternal bloodstream. This enzyme has anticoagulant properties.
