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 SPSS 14.
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 .
