Ultrasound examination (Ultrasonography) is an examination of the fetus using high frequency sound waves that are reflected off the body to find out an image of the uterus called a sonogram. The function of ultrasound examination is to determine the health of pregnancy development, especially that of the fetus. By using ultrasound it can determine the development of the baby, gestational age, growth and knowing the threat of miscarriage. Although now ultrasound examination is often performed every time a pregnancy check (control) is performed, it is best to only schedule the right time for the ultrasound examination.
Here is the exact schedule for ultrasound examinations during pregnancy:
1. Early Pregnancy
In the beginning pregnancy it is advisable to do an ultrasound examination. Examination in early pregnancy functions to determine the location of the fetus, the number of fetuses in the womb, the state of the internal genital organs and also to form the two ovaries so that they can be detected early if there are abnormal abnormalities. In addition, ultrasound examination in early pregnancy will help in determining an accurate gestational age.
2. Gestational Age 11-14
The second ultrasound examination will be carried out between 11-14 months of gestation. The examination at this second stage is to find out embryo growth one of which is related to Down syndrome (DS), a disorder related to the head, one of which is related to liquids in the brain cavity and brain disorders and scarring so that it can be detected early. Even the latest ultrasound has found the detection of abnormalities in the fetus at 9 weeks of pregnancy.
3. Gestational Age 18-23
The third stage, at 18-23 weeks of gestation, ultrasound examination will function to see congenital defects. At this stage it can also help determine whether the identification in the first inspection process is true or even if there is no possibility of a dangerous being found. The doctor has been able to explain the size of the fetal head circumference, upper arm length, thigh length, body weight, age of the baby and the location of the placenta. In addition, at this age it is very important in an ultrasound examination because it will provide an overview of umbilical cord function, fetal position and the amount of amniotic fluid.
4. Gestation Age 33-34 weeks
The last examination is recommended to be carried out at the time before delivery or in pregnancy that is overdue so that it aims to determine the growth of the fetus, the location of the placenta, the percentage of the fetus at the birth canal, the capacity of the amniotic fluid and the umbilical cord.
Although basically an ultrasound examination can be scheduled, if the condition of the pregnancy is experiencing problems such as an irregular fetal heartbeat, an ultrasound can be performed to determine the health condition of the fetus. Before you do an ultrasound, you can make preparations. Although the preparation depends on the ultrasound examination, here are the preparations you can do in the ultrasound examination:
- If the ultrasound is done through the female organs, you will need to empty the bladder first.
- As for ultrasounds that are performed outside, especially during pregnancy less than three months, you should first drink 2-3 glasses so that you have to make your bladder full enough so that you are asked to hold back urination before a doctor’s examination. This fluid serves to clarify the uterus and its contents behind the bladder.
