Resuscitation of patients who sustain a cardiac arrest as a result of trauma (traumatic cardiac arrest) has previously been described as 'futile'. Several published series have since contradicted this claim and reported survival-to-discharge data ranging from 0 to 35%. International resuscitation guidelines (European Resuscitation Council and American Heart Association) promote a consistent approach to cardiopulmonary resuscitation on the basis of up-to-date evidence and consensus opinions. This minimizes de-novo decision-making under high-stress situations, promotes a rational approach and reduces the burden on an individual clinician. This narrative review sets out to highlight the differences in aetiology of traumatic cardiac arrest as compared with medical cardiac arrest and the consequent priorities in resuscitation.
