Expecting mothers are typically offered ultrasound techniques to help monitor the growth and overall health of their baby. For instance, ultrasounds may be able to identify if the baby is suffering from some sort of physical deformity, such as an underdeveloped brain or improper functioning of the heart.
It may also be used to help determine the baby’s position, which would in turn impact the delivery method. At the end of the day, an ultrasound is designed to help protect both baby and mother.
But many expecting mothers may wonder if ultrasounds are safe for themselves and for their unborn babies.
Can Ultrasounds Negatively Affect the Baby?
A certain amount of heat is generated during a high resolution ultrasound, which is then absorbed by the belly that’s being scanned. For pregnancy-related ultrasounds, very little heat is generated, which means ultrasounds are very safe for both mother and baby.
The type of routine scanning that’s used to get 2-D images of the baby uses low-intensity ultrasound that’s spread out over a large surface area. In addition, any movement from the baby and the fluid that he’s in helps to disperse any heat.
A vaginal ultrasound might emit a bit more heat a little faster compared to scans through the tummy since the vaginal probe is warmed up by the mother’s body. However, the probe would need to be left inside the body for a long time for there to be any real danger from an increase in temperature.
