A Brief Introduction about 8 Week Ultrasound

A prenatal ultrasound, which is also called sonogram, is a noninvasive test. It basically makes use of sound waves to create a visual image of the pelvic organs, including the baby, placenta, and uterus. Via this test, the doctor is able to acquire vital information about the health of the baby and the progress of your pregnancy.

The first ultrasound is usually done around the 8th week of pregnancy. The purpose of an 8 week ultrasound is to confirm the date and duration of the pregnancy. The sex of the baby can be found out by the ultrasound that is done in the 16th to 20th week of pregnancy.

Ultrasound is also done with genetic tests for nuchal translucency scan that is meant to detect Down’s syndrome, chorionic villus sampling, and amniocentesis. If there are any complications expected in the pregnancy because the mother is diabetic, hypertensive, or suffering from any other medical condition, the interval between the ultrasounds is shortened.

The Information Attained Via an Ultrasound

With the help of an ultrasound, the medical practitioner finds out some essential information about the baby. He checks the heartbeat of the baby and if it sounds normal, the number of beats in a minute are counted to ensure that there are no abnormalities. The size of the baby is also measured to ensure that he is the right size for the gestational week. For instance, if the baby is bigger or smaller than the gestational age in the 8 week ultrasound, it is probable that the timing of the pregnancy has not been done in the right way. If the practitioner has any reason to believe that the baby is not growing at the desired rate, he will probe further to find out more. In the 8 week ultrasound, it is also checked whether it is a twin pregnancy or a singleton.

The location of the placenta is also checked to ensure that it is not covering the cervix, which can cause bleeding in the later stage of the pregnancy.

The amount of amniotic fluid present in the uterus is also assessed. Too much or too little amniotic fluid can pose a problem in pregnancy. If such a finding is positive on the ultrasound, a complete workup needs to be done to find out more about the cause of the problem. The anatomy of the baby is also checked in the ultrasound to find out if the baby is suffering from some congenital anomaly.

The Purpose of an Ultrasound in the First Trimester

There are several reasons that a practitioner might opt for an 8 week ultrasound, apart from dating the pregnancy.

1. Miscarriage

Vaginal bleeding in the early course of the pregnancy might

trigger the suspicion of miscarriage, and the practitioner would ask for an ultrasound to be done to confirm this. The heartbeat of the baby is visible on the ultrasound by six weeks of pregnancy, so if the baby’s heartbeat can be heard on the 8 week ultrasound, you can be certain that the pregnancy is progressing at the desired rate.

Sometimes, there is an error in dating the pregnancy. Thus, if a heartbeat is not heard at the 8th week of pregnancy, it is advisable to repeat the test a week later before deducing that something is wrong.

2. Ectopic or Molar Pregnancy

Vaginal bleeding with tenderness can point to ectopic or molar pregnancy. If it is a case of ectopic pregnancy, the embryo would not be in the uterus, and the doctor would have to determine the location of the embryo. In the case of molar pregnancy, there is an abnormal placental tissue present in the uterus that is without a viable baby. On the ultrasound, it would appear as a cluster of grapes.

3. When the Gestational Age is not Confirmed

Sometimes, the woman does not remember the date of her last menstrual period. Thus, dating the pregnancy becomes a difficult task. The 8th-week ultrasound can be done to find out more about her gestational age. The ultrasound is said to provide more accurate results rather than relying on the date of the last menstrual period.

The Purpose of an Ultrasound in the Later Course of Pregnancy

Now that we have discussed the purpose of an 8th-week ultrasound, let us shed some light on the reasons for the test being done in the third trimester of pregnancy.

1. Vaginal Bleeding

Complaints of vaginal bleeding in the later stages of pregnancy can be caused by different complications in pregnancy. An ultrasound will allow the practitioner to find out the cause.

2. Monitor Growth of the Baby

Sometimes, in the later stage of pregnancy, the practitioner might have doubts that the baby is not growing at the rate that he should be growing at. Thus, to assess the growth, an ultrasound might be ordered, which will allow the practitioner to measure certain parts of the body to monitor his growth.

3. Amniotic Fluid Level

If there were any abnormalities in the amniotic fluid level in the early stage of pregnancy, regular ultrasounds would be ordered in the later stages to monitor the condition of the baby.

4. Plan for C-section

An ultrasound might reveal information that would allow the practitioner to decide if a C-section is warranted. The situations in which C-section might have to be planned include breech presentation of the baby, the blockage of the passage of the baby through the placenta, or the baby is too large.

Duration of an Ultrasound

An ultrasound test tends to take about 15 to 20 minutes. If a more detailed evaluation needs to be done, the time might stretch to 30 to 90 minutes.

In the current times, the 8th-week ultrasound is done via the vagina. While this might be a tad bit uncomfortable, it is found to be more revealing and helpful than trans-abdominal ultrasound in the early stages as it will allow the practitioner to diagnose ectopic pregnancy and other fetal abnormalities.

If you opt for the trans-abdominal ultrasound for the 8th-week ultrasound, you would be asked to drink excessive water so that you would have a full bladder before the procedure. While it might be uncomfortable, it will make visualization of the baby easier and clearer.

Where to Get the Ultrasound Done from

Just getting the test done is not enough. You need to ensure that the place from where you get the test done has experienced personnel who would be able to read the results of the test in a proper manner. Since the ultrasound is meant to reveal valuable information, it is necessary that you do not be careless with regards to the place that you select to get the test done.

Side Effects to be Aware of

Numerous studies have been conducted to acquire information about the potential side effects of the test on the baby. So far, the evidence proves that there is no reason for you to worry. Even if the test is done multiple times, it does not affect the growth and development of the baby in any way.

If a Problem is Detected

If an abnormality is detected on the ultrasounds, there is no reason to fly into a panic mode. If there is a problem, the ultrasound will allow the practitioner to reach its root and deal with it accordingly. If the problem is detected at the right time, the practitioner can take the right steps and ensure that the health of the baby is not compromised.

There could be times when the doctor will recommend the termination of the pregnancy. At such times, you need to listen with attention to what he has to say and make your decision accordingly.
