Introduction and aims
Blunt abdominal trauma is a diagnostic challenge for
emergency physicians (E.P.s).
Ultrasonography (USG) is one of the diagnostic tools used
in this type of injuries.
Evaluate the diagnostic value of USG performed by E.P.s
and radiologists (RADs)
(based on comparisons with CT scanning as the gold standard)
Methods
Prospective diagnostic study
Emergency departments of two trauma centers in Iran
Inclusion criteria: all trauma victims with blunt abdominal trauma that underwent CT
scanning as a reference standard.
USGs were performed by E.P.s and then repeated by
RADs
The USG results were compared blindly with the results of
CT scans performed by RADs.
Results 1
450 patients were
included
Results 2
Conclusions and Discussion
Specificity, PPV and NPV were similar in most cases
RAD’s showed a higher performance regarding the
sensitivity of the USG diagnosis.
E.P.’s showed enough ability in ruling in the problem
Comparison between specialists…How about residents?
