    The thermal and mechanical indices are the best estimators of fetal risk in an ultrasound and their values should be controlled in order to minimize exposure as much as possible. We compared the values of the thermal and mechanical indices obtained in obstetric ultrasound examinations of pregnant patients, with the value recommended by the international community. These indices were estimated in 421 obstetric ultrasounds during 2019. The estimated values were compared with each other and with the recommended value for each index and according to the display mode (B, color Doppler and spectral Doppler). Of the total sample, for the thermal index in color Doppler mode, 0.24% exceeded the recommended standard value and 2.85%. in spectral Doppler mode. For the mechanical index, the recommended value was exceeded in B mode by 11.16%, in 8.08% in color Doppler mode and, finally, by 0.48% for spectral Doppler mode. The mechanical and thermal indices in this sample of obstetric ultrasound examinations are on average below the reference value. However, there is a significant number of cases in which the standards are exceeded, which should be a warning to the medical community. © 2022 Sociedad Chilena de Obstetricia y Ginecología.
