Using Right-Sided Roll to Improve Reliability of Focused Assessment with Sonography in Trauma: An Eastern Association for the Surgery of Trauma Multicenter Prospective Study.

Background: The Focused Assessment Sonography in Trauma (FAST) examination is the standard of care for detecting hemoperitoneum in hypotensive blunt trauma patients. A pilot study demonstrated earlier identification of intra-abdominal fluid via FAST after right-sided roll (FASTeR) when compared with the standard FAST. The purpose of this study was to evaluate this phenomenon prospectively in hypotensive blunt trauma patients.
