Traumatic Cardiac Arrest
Objective: Medical ACLS on a torso full of holes wastes the only minutes that matter. Reverse the reversible — airway, tension, hemorrhage — and move toward a surgeon, or follow your TOR rules.
Why This Is Hard
The monitor shows PEA and the team reaches for epinephrine by habit. In blunt or penetrating trauma, empty vessels, a kinked vena cava from tension, and an unsecured airway kill faster than a missed amiodarone. Some of these patients are salvageable if you fix what you can in seconds and leave. Some are not — and your termination-of-resuscitation rules exist so you do not create a second tragedy on a highway.
Priorities (Education)
The 2025 NAEMSP / ACS-COT / ACEP statement on traumatic out-of-hospital circulatory arrest (TOHCA) puts life-saving interventions (LSIs) first. Medical ACLS is not the template. Combat TCCC can be more aggressive for torso TCA — your protocol wins.
- Scene safety. External hemorrhage control (direct pressure, packing, tourniquets).
- Airway with the least-invasive approach that actually ventilates and oxygenates. Do not make the tube the whole call.
- Chest decompression if there is clinical concern for tension pneumothorax. Empiric bilateral decompression is not indicated in the absence of suspected chest trauma.
- Pelvic binder if the mechanism fits. Rapid toward a trauma center that can operate, when transport is still appropriate.
- External chest compressions may be considered, but they are secondary to those LSIs.
- Epinephrine should not be used routinely in traumatic arrest, and if used should not be given before the LSIs. If this looks like a medical arrest that happened to fall off a porch, treat the medical cause — but do not pretend a GSW to the chest is VF from cholesterol.
TOR / Futility Themes
- Know your protocol: unwitnessed blunt arrest with asystole, prolonged downtime, and no reversible cause often stop. Penetrating arrest that is fresh may still get a short, aggressive try plus transport in some systems.
- This lesson does not authorize you to stop or to continue. Medical direction and written TOR rules do.
Field Pitfalls
- 20 minutes of epinephrine on a parking lot for a torso GSW.
- Never looking at the chest or the bleeding.
- Calling it traumatic arrest when they clutched their chest at dinner and then wrecked the car (medical first).
- LSIs first: hemorrhage control, least-invasive effective airway, decompress if tension is a concern
- Empiric bilateral needles are not indicated without suspected chest trauma
- Compressions secondary; epinephrine not routine and not before LSIs
- TOR only per written protocol and medical direction — not a hallway vote
Practice
60-second drill
Two plans, 60 seconds each: (1) GSW chest, 2 min down — list LSIs in order and whether bilateral needles fit; (2) unwitnessed blunt rollover, asystole, 20 min — say TOR vs continue themes per your written rules. Related: Tension, Hemorrhage.
Sources & Further Study
Named guidelines for further study. They are not clinical orders and do not replace your protocol or medical direction.
- NAEMSP / ACS-COT / ACEP 2025: Prehospital Management of Adults with Traumatic Out-of-Hospital Circulatory Arrest
- TCCC guidelines (Committee on TCCC) — combat teaching may be more aggressive; protocol wins
- LSIs first: hemorrhage control, least-invasive effective airway, decompress if tension is a concern. Empiric bilateral needle decompression is not indicated without suspected chest trauma. Compressions are secondary. Epinephrine is not routine and not before LSIs. TOR only per written protocol and medical direction.
