A descriptive analysis of the epidemiology and management of paediatric traumatic out-of-hospital cardiac arrest

Abstract

AimPaediatric traumatic out-of-hospital cardiac arrest (OHCA) is a rare event with few survivors. We examined long-term trends in the incidence and outcomes of paediatric traumatic OHCA and explored the frequency and timing of intra-arrest interventions. MethodsWe retrospectively analysed data from the Victorian Ambulance Cardiac Arrest Registry for cases involving traumatic OHCA in patients aged ≤16 years arresting between January 2000 to December 2017. Trends were assessed using linear regression and a non-parametric test for trend. ResultsA total of 292 cases were attended by emergency medical services (EMS), of which 166 (56.9%) received an attempted resuscitation. The overall incidence of EMS-attended cases was 1.4 cases per 100,000 person-years, with no significant changes over time. Unadjusted outcomes also remained unchanged, with 23.5% achieving return of spontaneous circulation and 3.7% surviving to hospital discharge. The frequency of trauma-specific interventions increased between 2000–2005 and 2012–2017, including needle thoracostomy from 10.5% to 51.0% (p trend <0.001), crystalloid administration from 31.6% to 54.9% (p trend = 0.004) and blood administration from 0.0% to 6.3% (p trend = 0.01). The median time from emergency call to the delivery of interventions were: 12.9 min (IQR: 8.5, 20.0) for cardiopulmonary resuscitation, 19.7 min (IQR: 10.7, 39.6) for external haemorrhage control, 29.8 min (IQR: 22.0, 35.4) for crystalloid administration and 31.5 min (IQR: 21.0, 38.0) for needle thoracostomy. ConclusionThe incidence and outcomes of paediatric traumatic OHCA remained unchanged over an 18 year period. Early correction of reversible causes by reducing delays to the delivery of trauma-specific interventions may yield additional survivors.
