5 months pregnant fetal color Doppler ultrasound

During the ultrasound examination of the fetus in May, the following matters should be noted: the expectant mother should bring the previous examination materials with her as much as possible so that the doctor can compare them to understand the development status of the fetus. When checking the fetus, basic measurements and observations should be carried out first. First, the biparietal diameter, head circumference, abdominal circumference, and femoral diameter of the fetus should be measured to understand whether the growth and development of the fetus is in line with the gestational age. Then accurately measure the amount of amniotic fluid flow and observe the adhesion site of the embryo.

If in the early stages of pregnancy, such as in March, the embryo is found to be located relatively low, the expectant mother should be advised to hold her urine appropriately so that the internal os of the cervix can be clearly seen and observe whether the outer edge of the embryo is close to the internal os of the cervix. After the basic accurate measurement and observation of the fetus, it is also important to observe whether the fetus's growth and development has any malformations, such as common anencephaly, spina bifida, and visceral exstrophy.

In the fifth month of pregnancy, you can do a four-dimensional color ultrasound to check for fetal abnormalities. The fetal four-dimensional color Doppler ultrasound is performed between 22 and 24 weeks of pregnancy to screen the fetal central nervous system, digestive tract, urogenital system, urinary system, endocrine system, face, and respiratory system. Screening can be done for meningocele, hydrocephalus, cleft lip and palate, abnormal heart growth and development, abnormal lung growth and development, water retention in kidney function, incomplete urethral tube development, body deficiency, syndactyly, and visceral eversion.

Common questions about four-dimensional color ultrasound examination in May pregnancy: In May pregnancy, the baby's development has reached a critical period. At this time, we should first observe the baby's face, whether the upper lip is continuous, whether the ears are visible, whether the distance between the eyes and the bridge of the nose is symmetrical, whether the four chambers of the heart are symmetrical, whether the atrioventricular septum is continuous, the anatomical structure of the pulmonary artery and the pulmonary artery, the growth and development of the long bones of the limbs and the gastric bladder are within the normal range, observe the position and size of the placenta, the nominal diameter of the fetal umbilical cord and the blood are within the normal range, and the kidney display in May pregnancy is poor.
