For expectant mothers, many things need to be done well during pregnancy, such as supplementing nutrition and regulating the body. At the same time, comprehensive prenatal examinations should be carried out, such as checking fetal heart rate and fetal buds. Many pregnant women are not familiar with these tests, so they want to know if it is necessary to have an empty stomach to check for fetal heart rate and fetal sprouts?
It is necessary to perform abdominal ultrasound in order to check fetal heart rate and fetal bud. It does not require fasting, but it is necessary to hold urine for examination, and vaginal ultrasound examination can also be performed. The main purpose of ultrasound examination is to determine intrauterine pregnancy, exclude ectopic pregnancy, trophoblastic diseases, pelvic masses, etc., and determine the number of fetuses. If it is a twin fetus, the number and shape of the embryo sac can be used to determine the nature of the chorion and gestational age.
The timing of checking fetal heart rate and fetal sprouts is very important. During early pregnancy, some pregnant women have a strong curiosity and go to the hospital early for prenatal examinations. However, they may come to the hospital because the development of fetal heart rate and sprouts is slow, which requires repeated examinations. Normal fetal heart buds appear between 40-60 days of pregnancy, which is the golden period for examination at 8 weeks of pregnancy. The presence of fetal heart buds can be clearly detected.
In addition to the choice of time, the method of checking fetal heart rate and fetal sprouts is also important. There are two ways to detect fetal heart rate and embryo in early pregnancy, one is common abdominal ultrasound, and the other is negative ultrasound. If it is done before 8 weeks of pregnancy, the method of vaginal ultrasound examination should be chosen. Due to the presence of many errors in the examination of fetal heart and fetal buds by ultrasound, it is easy to be overlooked. On the contrary, after 8 weeks of pregnancy, ultrasound can be used to determine whether the fetal heart and fetal bud have appeared.
