Summary of "Contemporary Management of Traumatic Cardiac Arrest and Peri-Arrest States: A Narrative Review"

Abstract

Traumatic cardiac arrest (TCA) presents a unique clinical challenge with a historically poor prognosis. Advances in resuscitation techniques, such as the HOTT protocol (addressing hypovolemia, oxygenation, tension pneumothorax, and cardiac tamponade) and novel interventions like resuscitative thoracotomy (RT) and resuscitative endovascular balloon occlusion of the aorta (REBOA), have improved survival and neurological outcomes. This review discusses the pathophysiology, management strategies, and future directions for TCA.

Key Points

1. Epidemiology of TCA: Represents 4% of out-of-hospital cardiac arrests globally, predominantly affecting young males, with survival rates up to 10.6% in recent studies.
2. Primary Causes: Hypoxia, hypovolemia, tension pneumothorax, and cardiac tamponade are the leading reversible causes of TCA.
3. HOTT Protocol: Focuses on simultaneous management of hypovolemia, oxygenation deficits, tension pneumothorax, and tamponade to restore coronary perfusion pressure and achieve ROSC (return of spontaneous circulation).
4. Blunt vs. Penetrating Trauma: Penetrating trauma has higher survival rates due to treatable vascular injuries, whereas blunt trauma often involves multi-system damage.
5. Advanced Interventions: Resuscitative Thoracotomy (RT): Effective for cardiac tamponade and cases with signs of life (SOL) within specific time frames. REBOA: Temporarily occludes the aorta to control bleeding and improve proximal perfusion in exsanguinating patients.
6. Vascular Access Challenges: Rapid vascular access is critical. Intraosseous access offers speed, while central venous catheters provide higher flow rates for volume resuscitation.
7. Metabolic Management: Early correction of hyperkalemia and hypocalcemia is vital, as they frequently complicate severe hemorrhagic shock and massive transfusion.
8. Role of Vasopressors: Generally avoided in TCA except in hypoxic or central nervous system-related arrests, where low-dose boluses may be used judiciously.
9. Post-ROSC Care: Includes airway management, hemostatic resuscitation, and strategies to maintain normothermia and optimize oxygenation and perfusion.
10. Future Directions: Greater emphasis on training, prehospital interventions, and technology integration, such as portable ultrasound and blood products, to enhance TCA management.

Conclusion

Effective TCA management relies on rapid, simultaneous interventions targeting reversible causes and advanced procedures like RT and REBOA when indicated. A structured, team-based approach is critical for improving survival and neurological outcomes.

Discussion Questions

1. How can prehospital systems be optimized to deliver HOTT interventions rapidly and effectively?
2. What are the comparative benefits and limitations of REBOA versus RT in managing exsanguinating trauma?
3. How might future research improve early recognition and targeted interventions for TCA in resource-limited settings?
