Summary: A growth scan is a type of ultrasound scan done during pregnancy to check on the growth and development of the baby. It involves measuring the size of the baby, tracking their growth rate, and checking for any anomalies or complications
1. Why a growth scan is needed
A growth scan is recommended by healthcare providers if there is concern about the baby’s size, if there is a history of growth problems in previous pregnancies, or if the pregnancy is considered high-risk for other reasons. They are usually done between 28-40 weeks of pregnancy.
The ultrasound technician will measure the size of the baby’s head, abdomen, and thigh bone, and compare the measurements to those at previous scans. The technician will also examine the amount of amniotic fluid around the baby and the placement of the placenta.
A growth scan can help identify if the baby is too small or too large, which can indicate a potential problem with growth restriction or gestational diabetes, respectively.
2. What happens during a growth scan
A growth scan is similar to a regular ultrasound, and usually takes about 20-30 minutes. The mother lies on her back while the technician applies gel to her belly and uses a small handheld device called a transducer to take images of the baby inside.
The technician will use the ultrasound images to measure various parts of the baby’s body, including the circumference of the head and abdomen, and the length of the thigh bone. These measurements are used to estimate the weight of the baby and track their growth rate.
The amount of amniotic fluid around the baby will also be monitored during the scan. Normal levels of amniotic fluid are important for baby’s growth and development.
3. Risks and limitations of a growth scan
There are no known risks associated with having a growth scan, but as with any ultrasound scan, the gel used can cause mild skin irritation. Additionally, an ultrasound is not 100% accurate in estimating a baby’s weight, and there is a margin of error. Sometimes, a baby’s size can be overestimated, which can lead to unnecessary interventions such as induction of labor or C-section.
A growth scan cannot predict with certainty if a baby will have health problems after birth, but can provide valuable information about potential growth problems and help determine the best course of action.
It is important to note that a growth scan does not replace regular healthcare check-ups and monitoring during pregnancy in order to identify any problems early on.
4. What if a problem is detected?
If a growth problem is detected during a growth scan, your healthcare provider may recommend additional scans to monitor the baby’s growth more closely. Depending on the severity of the problem and how far along you are in your pregnancy, the provider may recommend inducing labor or performing a C-section.
In addition, if there are concerns about poor growth, the healthcare provider may recommend further testing such as a non-stress test, which monitors the baby’s heart rate as they move. If the test shows the baby is not getting enough oxygen, they may need to be delivered promptly.
Your healthcare provider will work with you to come up with the most appropriate treatment plan for you and your baby.
5. What to expect after a growth scan
After a growth scan, you may receive a report of the baby’s estimated weight and measurements. Your healthcare provider will usually review these results with you in your next prenatal appointment and discuss any concerns or recommendations based on the findings. If there are any issues, additional ultrasounds may be recommended.
In most cases, a growth scan provides reassurance that the baby is developing normally and there are no major complications. However, if a problem is detected, it is better to identify it early so that the appropriate actions can be taken to ensure the best possible outcome for both mother and baby.
Conclusion:
A growth scan during pregnancy is important for monitoring the baby’s growth and development and detecting any potential problems. Although there are no risks associated with having a growth scan, it is important to remember that there is a margin of error in estimating the baby’s weight. If a problem is detected, your healthcare provider will work with you to determine the best course of action to ensure the best possible outcome for both mother and baby.
To ensure a healthy pregnancy, it is important to attend all scheduled prenatal appointments and follow your healthcare provider’s advice and recommendations.
