The four-dimensional color ultrasound must be carried out strictly according to the schedule, because doing it too early or too late will affect the results of the pregnancy test and create difficulties for the prenatal examination.

What should I pay attention to when doing four-dimensional color ultrasound?

During pregnancy, pregnant mothers have to go through dozens of prenatal checkups, but the four-dimensional color ultrasound is the most torturous. Some pregnant mothers have done it five or six times, but finally give up with regret and helplessness. The reason for this situation is that the fetus does not cooperate!

1. Four-dimensional color ultrasound needs to be booked in advance: Four-dimensional color ultrasound is the most important prenatal examination item. Although it is all based on B-ultrasound, compared with basic B-ultrasound, four-dimensional color ultrasound takes longer, and the shortest time is about 30 minutes. In order to avoid the situation where pregnant mothers have to wait in long lines, they must book the specific time for the pregnancy test in advance, and arrive at the hospital 10 minutes early on the day of the test.

2. Four-dimensional color ultrasound does not require fasting: Four-dimensional color ultrasound does not require fasting, and doctors prefer pregnant mothers to eat well, because the fetus is more active, which is also conducive to the one-time completion of the four-dimensional color ultrasound. You don't need to hold your urine for 4D color Doppler ultrasound~

3. Choose the right time range for four-dimensional color Doppler ultrasound: when the fetus is actively moving, it is more convenient for the doctor to comprehensively examine the growth and development status of each organ and part of the fetus. Pregnant mothers can choose to do a pregnancy test one hour after a meal or after a nap.

4. Develop the habit of communicating with the fetus: After four months, the fetus's auditory system has basically developed and mature, and pregnant mothers can choose to perform music prenatal education or verbal communication with the fetus every day. On the day of the prenatal check-up, you can stroke the pregnant woman's belly and say to the fetus, "I'm going to take a photo with the baby today, so you must cooperate obediently." Many pregnancy tests are valid! !

5. Bring some chocolate: If the fetus does not cooperate during the prenatal checkup, the pregnant mother can eat some chocolate appropriately to increase the blood sugar level in the body. The fetus will become more active under the stimulation of sugar. Some doctors also recommend pregnant mothers to climb stairs or jump. Pregnant mothers must pay attention to the safety of their feet and wear flat shoes.

Four-dimensional color ultrasound takes a relatively long time, so pregnant mothers must choose left-right split clothes that are warm and comfortable, which are easy to put on and take off and will not cause embarrassment to pregnant mothers.
