  • Introduction: Objective: Focused assessment with sonography in trauma (FAST) is a very valuable part of the initial examination in emergency care. the aim of this study is to define the recent role of FAST and CT scan of the abdomen in the diagnosis of blunt abdominal trauma.
  • Methods: Method: A cross-sectional study on 150 blunt abdominal trauma patients who were admitted to the emergency department of Khatam Zahedan Hospital in 2021. The findings of FAST and CT scan were compared after extracting from the patient's records. In comparison to CT Scan as a reference, the sensitivity, specificity, PPV and NPV of FAST were evaluated.
  • Results: Findings: The patients included 109 men and 41 women with an average age of 35.7 ± 25.8 years, the youngest was 19 years old and the oldest was 70 years old. The most injuries were due to accidents (40 cases), falls (50 cases) and impact (60 cases). The condition of the patients was such that about 97% of the patients had triage level 2. The sensitivity was 75%, the specificity was 98.6%, the positive predictive value was 60%, and the negative predictive value was 99.3%.
  • Conclusion: Conclusion: FAST is a high diagnostic value in the screening of patients with blunt abdominal trauma. FAST is a reliable tool for examining trauma patients and due to the constant presence of emergency medicine specialists at the patient's bedside in the early moments, it plays a significant role in improving the treatment protocol of trauma patients.
