OBJECTIVE: There is a paucity of evidence demonstrating that @entity341 ( @entity341 ) ultrasound changes clinical practice in @entity130 @entity1 . We hypothesized that the presence of ultrasound would affect clinical decision making as evidenced through abdominal computed tomographic (CT) scan use in blunt @entity1230 @entity1 . METHODS: This study used a prospective randomized format in an urban county @entity341 with Level II @entity130 center status ( @entity341 census, 72,000 @entity1 per year). @entity1 were @entity1 with @entity1913 meeting @entity130 center triage criteria. @entity1 were randomized to receive either abdominal ultrasound or no ultrasound (control) during initial @entity341 resuscitation. The primary outcome variable was use of abdominal CT scan in @entity1 with and without ultrasound. RESULTS: Two hundred eight @entity1 were enrolled. The mean age was 40 +/- 18 years, and 62% were @entity1 . Mechanism of injury was motor vehicle crash, 56%; automobile versus pedestrian, 18%; motorcycle crash, 16%; falls, 10%; and other, 10%. One hundred four ultrasound and 104 control @entity1 were analyzed. There were no apparent differences between ultrasound and control groups in demographics, @entity130 , or Injury Severity Score. Fifty-four of 104 (52%) of the control group received abdominal CT scans versus 37 of 104 (36%) abdominal CT scans for the ultrasound group; mean difference in proportions was 15.9 (p < 0.01; 95% confidence interval, 2.6-29.1). CONCLUSION: In this trial, the routine use of abdominal ultrasound in the evaluation of @entity1 with @entity1913 resulted in significantly fewer abdominal CT scans being obtained. A larger trial is needed to more clearly define the clinical and financial impact of ultrasound in the management of blunt @entity1661 .
