When pregnant women undergo 4D ultrasound examination, they need to make some preparations before the examination, such as proper diet, moderate activity, reasonable dressing, etc., which need to be analyzed specifically.
1. Appropriate diet: when doing 4D ultrasound, you don’t need to have an empty stomach, instead, you need to eat more food to provide energy for the fetus, so that the fetus can move around fully during the examination, so that you can observe it more clearly.
2. Moderate activity: If the fetus is inactive during the examination, the pregnant woman should move around moderately to make the fetus active for easy observation.
3. Reasonable clothing: During pregnancy checkups, pregnant women need to wear loose-fitting clothes, while the checkups take a long time, so they should pay attention to preventing from getting cold.
Pregnant women usually undergo 4D ultrasound examination of the fetus at 22-26 weeks, which is of great significance in ruling out fetal malformations, and it is recommended that pregnant women actively undergo it to promote the healthy development of the fetus.
