The difference between fetal monitoring and B-ultrasound After pregnancy, the whole pregnant woman should do a series of related examinations, among which B-ultrasound should be done in the early, middle and late stages of pregnancy, and fetal heart monitoring usually begins after 34 weeks. These two tests are different.
Fetal heart monitoring, that is, using the detection instrument, that is, the monitoring probe of fetal heart rate, continuously monitors the change of fetal heart sound, and can also monitor the examination of uterine tension, mainly to judge whether the fetus has intrauterine hypoxia.
B-ultrasound is a kind of examination that can detect fetal growth, development, structure and fetal heart, and can also detect fetal appendages, namely amniotic fluid, umbilical cord and placenta. So these two are different inspection methods.
The accuracy of fetal monitoring and fetal heart monitoring is more accurate than that of B-ultrasound. Fetal monitoring is usually carried out in the third trimester. B-ultrasound only looks at the law of instantaneous fetal heart beating, and fetal heart monitoring takes at least 20 minutes! Fetal heart monitoring is a continuous test, mainly to see the changes of fetal heart after fetal movement. If the average value of fetal heart monitoring is within the normal range. Because it is possible that the baby will turn over or press the umbilical cord in it! B-ultrasound can clearly display all kinds of sectional images of various organs and surrounding organs. Because the image is full of three-dimensional sense and close to the real anatomical structure, the application of ultrasound can make a clear diagnosis at an early stage. For example, when diagnosing nonmetallic foreign bodies in ophthalmology, retinal and retrobulbar lesions can be displayed in the case of vitreous opacity. It is specially used for non-invasive detection of congenital heart disease, rheumatic heart disease and myxopathy, and can replace most distracting catheterization. It can also be used to determine the connection and disconnection of small blood vessels, the direction and speed of blood flow, and can be widely used. Early detection of liver space occupying lesions has reached the level of 65438±0cm. It can also clearly show the common bile duct of gallbladder, hepatic duct, extrahepatic bile duct, pancreas, adrenal gland, prostate and so on.
Causes of poor fetal heart monitoring The more serious the fetal heart abnormality, the more severe the fetal hypoxia, but not all fetal heart abnormalities are caused by hypoxia. In addition to the above situation, the pregnant woman's own situation also affects the change of fetal heart rate. For example, pregnant women have a fever, and the fetal heart rate often exceeds 160 beats/minute. Pregnant women have hyperthyroidism, their own heart rate is very fast, and the fetal heart rate often exceeds 160 times.
Getting pregnant in October is really a hard thing. Pregnant mothers should control their diet and pay attention to many things for the health of their children, but as long as they can give birth to a healthy baby, I believe that mothers will think it is worthwhile. Therefore, pregnant mothers must insist. Usually it is more necessary to keep a good mood.
Women will worry about many problems when they are pregnant, so pregnant women need to do various tests to know whether the fetus is healthy, but not all the results are good without pregnant women's tests. Some pregnant women have poor fetal monitoring.
