RODRIGUEZ MUSIBAY, Isbel  and  VALLE RIANO, Rubén Ángel. Safety of obstetric ultrasonography for maternal and fetal health. Rev Cubana Obstet Ginecol [online]. 2016, vol.42, n.3, pp. 386-397. ISSN 1561-3062.

Diagnostic ultrasonography has always been a controversial topic, and obstetric ultrasound has not been outside the debate. Many different criteria have been held about the subject: some state that the method is totally safe, while others have a reserved opinion, and still others refer to negative effects on the fetus. Because tissues absorb sound waves, turning them into thermal energy, the higher the energy the more risks there will be of bioeffects on the fetus. The risk increases when pregnant women have a fever. On the other hand, the personnel performing the test have scarce knowledge about the acoustic output of the equipment they use, as well as the bioeffects and the safety of ultrasound in general. This is a worldwide fact. We should be aware of the need to use the lowest energy density reasonably required to obtain data and images useful for diagnosis. Health professionals should comply with the guidelines on the use of obstetric ultrasound to prevent unnecessary exposure to sound waves by mothers and fetuses.

Keywords : ultrasound; fetus; pregnancy; bioeffects.
