Combination of Focused Assessment With Sonography for Trauma (FAST) Scan and Detection of Hematuria to Exclude Intra-abdominal Injuries Following Blunt Abdominal Trauma.

Background Blunt abdominal trauma (BAT) is the most common pattern of abdominal traumas. It may be associated with intra-abdominal injuries (IAIs). Exploratory laparotomies are only needed in a minority of patients after BAT. Methodology All BAT patients who presented to the El Demerdash Hospital of Ain Shams University, Cairo, Egypt during the study period were traced. Parameters including demographic data, focused assessment with sonography for trauma (FAST) scan, CT scan results, and hematuria were collected. The cohort was divided according to the CT scan results into two groups: patients with IAIs and patients without IAIs. Results Males represented 78.2% of the patients, and the mean age of the recruited patients was 32.1 ± 18 years. Road traffic accidents represented the main cause of trauma (58%) Patients with IAIs detected by CT scan represented 1.62%, and hematuria was detected in 88.9% of them. The specificity of FAST was 97.1%, and that of hematuria was 84.1%, and for the combination of both tests, the specificity was 99.3%. Conclusion IAIs after BAT can usually be excluded if both FAST and hematuria are negative, provided that the patient is stable.
