Epidemiology and aetiology of paediatric traumatic cardiac arrest in England and Wales.

OBJECTIVE: To describe the epidemiology and aetiology of paediatric traumatic cardiac arrest (TCA) in England and Wales.

DESIGN: Population-based analysis of the UK Trauma Audit and Research Network (TARN) database.

PATIENTS AND SETTING: All paediatric and adolescent patients with TCA recorded on the TARN database for a 10-year period (2006-2015).

MEASURES: Patient demographics, Injury Severity Score (ISS), location of TCA ('prehospital only', 'in-hospital only' or 'both'), interventions performed and outcome.

RESULTS: 21 710 paediatric patients were included in the database; 129 (0.6%) sustained TCA meeting study inclusion criteria. The majority, 103 (79.8%), had a prehospital TCA. 62.8% were male, with a median age of 11.7 (3.4-16.6) years, and a median ISS of 34 (25-45). 110 (85.3%) had blunt injuries, with road-traffic collision the most common mechanism (n=73, 56.6%). 123 (95.3%) had severe haemorrhage and/or traumatic brain injury. Overall 30-day survival was 5.4% ((95% CI 2.6 to 10.8), n=7). 'Pre-hospital only' TCA was associated with significantly higher survival (n=6) than those with TCA in both 'pre-hospital and in-hospital' (n=1)-13.0% (95% CI 6.1% to 25.7%) and 1.2% (95% CI 0.1% to 6.4%), respectively, p<0.05. The greatest survival (n=6, 10.3% (95% CI 4.8% to 20.8%)) was observed in those transported to a paediatric major trauma centre (MTC) (defined as either a paediatric-only MTC or combined adult-paediatric MTC).

CONCLUSIONS: Survival is possible from the resuscitation of children in TCA, with overall survival comparable to that reported in adults. The highest survival was observed in those with a pre-hospital only TCA, and those who were transported to an MTC. Early identification and aggressive management of paediatric TCA is advocated.
