1. Amniotic fluid
Amniotic fluid is the liquid in the uterus for babies to breathe and survive, which is related to the safety and development of babies. Too much amniotic fluid and too little amniotic fluid will affect your baby's health.
The amniotic fluid index that meets the standard is 8-24 cm; The depth of amniotic fluid is exactly 3-8cm.
2. Fetal heart rate
Four-dimensional color Doppler ultrasound can also detect the fetal heart rate, which is the beating frequency of the fetal heart and directly reflects the baby's health. The fetal heart rate is between 120- 160 beats/min.
3. Fetal size
At all stages of pregnancy, the height and weight of the fetus have corresponding standard values. Four-dimensional color Doppler ultrasound can get the data of head circumference and femur length, so as to judge the baby's weight.
At 32 weeks of pregnancy, the average femur length is 6.2cm, but it is normal in the range of 5.7-6.9cm. What is the biparietal diameter (BPD) of full-term infants? 10cm is more conducive to natural delivery.
4. Number of turns of umbilical cord around neck
Umbilical cord around the neck is something that every mother is worried about. If the number of weeks around the neck before labor is still more than 2.5 weeks, it is not recommended to choose natural labor.
Four-dimensional color Doppler ultrasound can see the number of weeks of the baby's umbilical cord around the neck, thus adjusting the amount of exercise during pregnancy.
What should Ma Bao do if the baby refuses to show his face after four-dimensional prenatal examination?
Many treasure mothers often fail to do four-dimensional color Doppler ultrasound for the first time. It's not that there's anything wrong with the baby, but that this little guy doesn't cooperate at all. Ma Bao can make some preparations in advance for this.
1. Stabilize your mood
The mood of the fetus will also be influenced by the mother. If Ma Bao is too nervous and anxious, the baby will fidget. Therefore, for the four-dimensional pregnancy test, Ma Bao should control his emotions, don't get too excited, and try to calm his emotions.
Eat something
Four-dimensional color Doppler ultrasound can not hold back urine, but also eat. If the baby doesn't cooperate when doing four dimensions, you can cover your face with your hands and other actions, or you can eat something, preferably sweets to stimulate your baby. Maybe you'll take your hands off me.
take exercise
We can often see pregnant women walking up and down the corridor before doing a four-dimensional clinic. The activities of pregnant women can effectively change their posture.
