Implementation of video laryngoscopes and the development in airway management strategy and prevalence of difficult tracheal intubation: A national cohort study
Authors' conclusion
From 2008 to 2016, a period of massive implementation of video laryngoscopes, a significant change in airway management behaviour was recorded.
Study context
- Population
- Tracheal intubations recorded 2008–2016 in the Danish Anaesthesia Database
- Participants
- 822,259 tracheal intubation records
- Exposure
- Airway management by year of observation, 2008 vs 2016
- Outcome
- Development in use of video laryngoscopy and its impact on airway planning and management
Methodological detailsnational registry (Danish Anaesthesia Database), multivariate logistic regression
- National registry (Danish Anaesthesia Database)
