SOMA 26' - Ultrasound-Augmented Triage A Proposal To Refine Field Decision Making In Tactical Combat Casualty Care

<p>Recorded live at SOMA 26</p><p>In a near-peer MASCAL, one medic and one junior medic may face twenty penetrating torso casualties, one unit of blood, and no time to empirically needle or finger-decompress every chest. This SOMA presentation argues that formal triage algorithms are already giving way to intuitive, intervention-first decisions—and that point-of-care ultrasound can make that second pass objective. The proposed two-pass model keeps MARCH as a fast first pass (urgent vs non-urgent), then uses a three-view POCUS exam—parasternal or subxiphoid cardiac motion, pericardial effusion, and bilateral lung apices—completed in under 30 seconds to decide who gets blood, who needs targeted decompression, who needs a surgical airway to thoracotomy or pericardiocentesis, and who is unsurvivable cardiac standstill. Speakers review trauma-arrest survival data, needle-decompression overuse, SOF medic training at Henry Ford (RUSH exam and the abbreviated 30-second protocol), and civilian paramedic programs showing that short courses can produce usable scans that change management. </p><p>Sponsored by the Special Operations Medical Association.</p><p><br></p><p>Key Takeaways</p><ul><li>Empiric bilateral chest decompression and “treat everybody” TCCC habits will not scale in large MASCALs when blood, time, and procedural capacity are scarce.</li><li>Formal algorithms are often unused in real events; medics already default to intuitive triage. The missing piece is an objective tool that separates salvageable from unsurvivable casualties.</li><li>Published decompression data show low response rates, high practice variation, and procedures performed on patients who did not meet criteria—driven by subjective breath sounds.</li><li>Cardiac motion on ultrasound is the strongest practical field marker of salvageability in pulseless trauma; standstill without tamponade is associated with essentially no survival and should conserve blood and procedures.</li><li>A three-view exam (cardiac motion, pericardial effusion, pneumothorax) can be completed in ~25–30 seconds. SOF medics approached expert performance after focused training; civilian paramedics have shown usable accuracy after 4–8 hour courses.</li><li>Positive findings should drive action: motion → consider blood; effusion + access to thoracotomy/pericardiocentesis → prioritize evacuation/intervention; no lung slide → targeted decompression rather than bilateral empiric procedures.</li></ul><p><br></p><p>Chapters<
