Focused assessment with sonography for trauma (FAST), on the other hand, is an important and valuable diagnostic alternative to DPL (Diagnostic Peritoneal Lavage) and CT that can often facilitate a timely diagnosis for patients with BAT(Blunt abdominal Trauma)
The benefits of the FAST examination include the following:
- Decreases the time to diagnosis for acute abdominal injury in BAT
- Helps accurately diagnose hemoperitoneum
- Helps assess the degree of hemoperitoneum in BAT
- Is noninvasive
- Can be integrated into the primary or secondary survey and can be performed quickly, without removing patients from the clinical arena
- Can be repeated for serial examinations
- Is safe in pregnant patients and children, as it requires less radiation than CT
- Leads to fewer DPLs; in the proper clinical setting, can lead to fewer CT scans (patients admitted to the trauma service and to receive serial abdominal examinations)
