Short- and long-term risks after exposure to diagnostic ultrasound in utero.


A total of 425 children exposed to diagnostic ultrasound at three Denver hospitals during the period May, 1968, through August, 1972, and 381 matched control children were studied for adverse effects at birth and again at a special examination between seven and 12 years of age. Apgar scores, gestational age, head circumference, birth weight, length, congenital abnormalities, neonatal infection, and congenital infection were measured at birth. At seven to 12 years of age, measurements included conductive and nerve measurements of hearing, visual acuity and color vision, cognitive function, behavior, and a complete and detailed neurologic examination. No biologically significant differences between exposed and unexposed children were found.
