1. Prenatal examination: Regular prenatal examination is an important way to know the health status of the fetus. These examinations include ultrasonic examination, blood examination, urine examination, etc. Ultrasonic examination can observe the development, organ structure and heartbeat of the fetus, and blood and urine examination can evaluate the health status of the mother and whether there are potential problems.
2. Fetal movement observation: Fetal movement is an important indicator of fetal health. Usually, pregnant women will begin to feel fetal movement around 20 weeks of pregnancy. The frequency and intensity of fetal movement increase gradually every day. If you feel that the fetal movement is obviously reduced or stopped, you should consult your doctor in time.
3. Amniotic fluid index: Amniotic fluid is the fluid around the fetus, which is very important for the protection and development of the fetus. Amniotic fluid volume can be measured by ultrasonic examination. Under normal circumstances, the amniotic fluid index should be between 5 and 25. If the amniotic fluid index is abnormally low or high, it may indicate that the fetus has a problem.
4. Fetal heart monitoring: Fetal heart monitoring is a method to evaluate the health status of the fetus by monitoring the heartbeat of the fetus. This can be achieved by an external fetal heart monitor or an internal fetal heart monitor. The normal fetal heart rate range is 1 10- 160 beats per minute.
5. Prenatal screening and diagnostic examination: Prenatal screening and diagnostic examination are helpful to detect whether there are some hereditary or congenital diseases in the fetus. Common prenatal screening includes Down syndrome screening and trisomy screening. If the screening results are abnormal, further diagnostic tests, such as amniocentesis or chorionic villus biopsy, may be suggested.
Please note that the above methods and indicators are only part of the assessment of fetal health, and the specific judgment needs to be combined with the professional opinions of doctors and other relevant examination results. If you have any questions or concerns about fetal health during pregnancy, it is recommended that you consult a professional obstetrician in time.
