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.
STUDY DESIGN: An Eastern Association for the Surgery of Trauma-approved multicenter prospective trial was performed June 2016 to October 2020 at 8 designated trauma centers. Hypotensive adult blunt trauma patients were included. A traditional FAST examination was performed. After this, the secondary survey logroll for back examination was standardized to the patient's right side. A repeat supine right upper quadrant ultrasound view was obtained. The presence or absence of hemoperitoneum was confirmed by CT scan or intraoperative findings. FAST and FASTeR were compared using receiver operating characteristics. The area under the curve was calculated.
RESULTS: A total of 182 patients met inclusion criteria. A total of 65 patients (35.7%) had hemoperitoneum on CT scan or intraoperative findings. The sensitivity of FASTeR was 47.7%, and of FAST was 40.0% (p = 0.019). The receiver operating characteristics area under the curve of the FASTeR examination was 0.717 vs 0.687 for the FAST examination (p = 0.091).
CONCLUSIONS: Addition of a right upper quadrant view after right-sided roll does improve the sensitivity of the FAST examination while maintaining the standard positive predictive value. We demonstrate a trend that does not reach statistical significance about the overall accuracy. This multicenter prospective trial was underpowered to reveal a statistically significant difference in the overall accuracy as measured by the receiver operating characteristics area under the curve.
