Accuracy of surgeon performed sonography in blunt abdominal trauma

Aims: Focused Assessment with Sonography for Trauma (FAST) is used as a screening tool to detect hemoperitoneum in patients with blunt abdominal injuries in many trauma centers all over the world. However, Iranian trauma centers are unaccustomed to performing it as a routine. The aim of this study was to evaluate the sensitivity and specificity of FAST performed by surgeons and to announce its advantages to Iranian surgeons Materials & Methods: Data were collected prospectively in one hundred blunt abdominal trauma patients admitted to Baqyiatallah Hospital from April 2008- April 2009. FAST was used by surgeons or senior surgical residents to detect intra peritoneal fluid and considered positive if such fluid was identified. Data were analyzed using SPSS14. Results: 5 of the 100 patients had proven intra abdominal injuries and 95 had no injuries. FAST result was positive in 7 patients and negative in 93 patients. There were 2 false positive results. The sensitivity and specificity of FAST were 100% and 97.8%, respectively. The positive predictive value was 71.4%, the negative predictive value was 100% and the accuracy was 98%. Conclusion: Focused Assessment with Sonography for Trauma which is performed by general surgeons, can detect the presence or absence of intra peritoneal fluid rapidly and accurately. FAST is a potentially valuable tool for better management of trauma patients. Keywords: Blunt Abdominal Trauma, Focused Assessment with Sonography for Trauma (FAST), Sensitivity, Specificity
