Does the Exposure to Ultrasound Relate to Delayed Speech in Children?

Sunday, 23 November 2008 14:17

The purpose of this study was to determine whether there is an association between prenatal ultrasound exposure and delayed speech in children. The results showed that the children with delayed speech had a higher rate of ultrasound exposure than the control subjects. The findings suggest that a child with delayed speech is about twice as likely as a child without delayed speech to have been exposed to prenatal ultrasound waves The authors concluded that an association between prenatal ultrasonography exposure and delayed speech was found. If there is no obvious clinical indication for diagnostic in-utero ultrasonography, physicians might be wise to caution their patients about the vulnerability of the fetus to noxious agents.
