The pregnancy experience is a wonderful one, but unfortunately it is a hectic one that accompanies a lot of medical appointments and new terms and jargon. If you are given a prescription for a "USG Obstetric" by your health professional you may find it a little high tech or a bit frightening. Clarify the medical jargon, though, and you're left with one of the most beautiful and eagerly awaited moments of your pregnancy. This is the actual visual interpretation of your baby inside of you, a time to see your baby developing and to be sure they are very well.
What is a USG Obstetric?
A USG (Ultrasonography) Obstetric is a specialized ultrasound that focuses specifically on the monitoring of a developing fetus, its placenta, amniotic fluid and the mother's reproductive organs. In contrast to X-rays, which use the more harmful ionizing radiation, this cutting edge technology only uses the soft and high-frequency sound waves. These acoustic waves reflect off the internal structures, and are then displayed in sharp, real-time images on a screen. It is well known as one of the best and non-invasive tests used for maternal and fetal health assessment, with zero risk.
What makes this Scan so critical?
Your doctor will use the Obstetric USGs wisely during your pregnancy to collect important information. This scan has a few key functions in each trimester:
First Trimester (Dating & Viability): This scan is crucial during the first weeks of pregnancy to confirm the development of the pregnancy, determine the Estimated Date of Delivery (EDD) and experience the first movement of the baby's heartbeat.
Second Trimester (The Anatomy Scan): This is a detailed scan that checks for all the different structures of the baby and is performed around the 20th week. The sonographer thoroughly examines the baby's brain, heart, spine and limbs to ensure proper anatomical development.
Third Trimester (Growth & Position): nearing the end of your journey you'll be thinking about the baby's growth pattern. The doctor will examine the level of the amniotic fluid, check the position of the placenta, and look at the baby's position (e.g., head down) before attempting the safe delivery.
What's happening in the Exam Room?
It's a very simple and calming process. You may be asked to come in with a full bladder if you're in the first few weeks of pregnancy, because this makes the uterus higher up for better acoustic visibility.
You will be lying down on an exam table so that you can lay back and relax. The tech will liberally coat your abdomen with a hypoallergenic, water-based aqueous gel. The gel is an ideal conductor of sound waves. They will then gently pass a hand-held machine called a transducer over your skin to get 3D, high-resolution views of your baby.
Is USG Obstetric a safe and painless test?
Yes, there is no pain, no needles or discomfort with the procedure. It uses sound echoes not radiation and therefore cannot harm your baby's developing cells.

Frequently Asked Questions (FAQs)
Do I have to fast before coming to the clinic?
No, it is ok to have your regular meals prior to a pregnancy ultrasound. You may need to have a full bladder of water in your first trimester only.
May my partner join me in the room?
Yes! This is a very special event and we would love to have you be there to celebrate with us as we get to hear the baby's heartbeat and celebrate the baby's arrival.
What is the total scan time for the whole scan?
The majority of standard obstetric scans can be done easily in 20-30 minutes, although in the second trimester a more thorough ultrasound examination of the baby's anatomy may take a bit longer to ensure all the details are covered.
