BackgroundEarlier studies have shown variable results regarding the success of paediatric emergency endotracheal intubation between different settings and operators. We aimed to describe the paediatric population intubated by physician-staffed helicopter emergency medical service (HEMS) and evaluate the factors associated with overall and first-pass success (FPS).MethodsWe conducted a retrospective observational cohort study in Finland including all children less than 16 years old who required endotracheal intubation by a HEMS physician from January 2014 to August 2019. Utilising a national HEMS database, we analysed the incidence, indications, overall and first-pass success rates of endotracheal intubation.ResultsA total of 2731 children were encountered by HEMS, and intubation was attempted in 245 (9%); of these, 22 were younger than 1 year, 103 were aged 1-5 years and 120 were aged 6-15 years. The most common indications for airway management were cardiac arrest for the youngest age group, neurological reasons (e.g., seizures) for those aged 1-5 years and trauma for those aged 6-15. The HEMS physicians had an overall success rate of 100% (95% CI: 98-100) and an FPS rate of 86% (95% CI: 82-90). The FPS rate was lower in the youngest age group (p = .002) and for patients in cardiac arrest (p < .001).ConclusionsEmergency endotracheal intubation of children is successfully performed by a physician staffed HEMS unit even though these procedures are rare. To improve the care, emphasis should be on airway management of infants and patients in cardiac arrest.© 2021 The Authors.
