AbstractProspective studies have shown sensitivities of 73% to 88% and specificities of 98% to 100% for using the focused assessment with sonography for trauma (FAST) examination to identify free fluid in adult trauma patients. However, the efficacy of FAST examinations for pediatric trauma patients has not been well defined, and studies looking at diagnostic performance have had varied results. We describe 3 cases of the potential pitfalls of the pediatric FAST examination in pediatric trauma patients using an advanced-processing ultrasound machine. We hypothesize several etiologies for these false-positive findings in the setting of advanced image-processing capabilities of point-of-care ultrasound. We also discuss the reevaluation of clinical algorithms and interpretation practices when using the FAST examination in pediatric trauma.© 2018 by the American Institute of Ultrasound in Medicine.
