Traumatic cardiac arrest

Abstract

Purpose of review This review considers the latest evidence relating to the epidemiology and outcomes, treatment guidelines, diagnostic and therapeutic interventions in traumatic cardiac arrest. Recent findings There is variation in the incidence and outcomes of traumatic cardiac arrest which is influenced in part by case definitions. Irrespective of case definitions outcomes from traumatic cardiac arrest are typically worse than those seen from cardiac arrest due to medical causes but not so poor as to consider that treatment is futile. Clinical guidelines focus on the prompt treatment of reversible causes, although evidence that this improves outcomes is limited. Point of care ultrasound to assist with the identification of reversible causes should be limited to experienced operators where there is thought to be a high likelihood of a reversible cause being present. Care should be taken to minimize interruptions in chest compressions during scanning. There is little recent evidence to support specific therapeutic interventions. The role of Resuscitative Endovascular Balloon Occlusion of the Aorta during traumatic cardiac arrest remains to be determined in on-going research. Conclusion Trauma related cardiac arrest differs from cardiac arrest due to medical causes. Whilst the core principles of treatment are similar, a higher priority is placed on identifying and treating reversible causes.
