Frequency, indications and success of out-of-hospital intubations in Finnish children

Abstract

Background: Earlier 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). Methods: We 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. Results: A 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
