Pregnant mothers who have had a B-ultrasound examination know that doctors will let pregnant mothers hold their urine before the examination, so it is really annoying to drink a lot of water at once. Pregnant mothers who don't want to urinate for the time being may deliberately drink more water before going to the hospital, but they found that the four-dimensional examination didn't need to urinate at all.

Besides not peeing on purpose, pregnant mothers also need to pay attention to the choice of clothes. Compared with other B-ultrasound examinations, this examination takes a long time, so it is best for pregnant mothers not to wear conjoined clothes, and it is most comfortable to choose clothes with loose tops and trousers separated.

Matters needing attention in inspection

The four-dimensional examination is mainly to detect the baby's physical condition in detail. The doctor will carefully check every part of the baby to ensure that every abnormal situation is checked in place so as to respond as soon as possible. Therefore, the whole examination process takes a long time, so the mother should be patient and not nervous, otherwise it will affect the state of the fetus, leading to inaccurate examination results, and even have to find another time to check again.
