Study Notes
Unanticipated and Emergency Difficult Airway Management
- Unanticipated and emergency difficult airway management involves 7 key interventions: calling for help, optimizing oxygenation, using a cognitive aid, utilizing noninvasive airway management devices, employing combination techniques, performing invasive airway management interventions, and using ECMO.
Literature Findings
- There is insufficient literature to evaluate patient outcomes associated with immediate access to airway management support equipment or calling for help.
- The literature is also insufficient to evaluate difficult airway patient outcomes associated with the use of a visual aid, cognitive aid, or algorithm for unanticipated or emergency difficult airways.
Case Reports and Devices
- Case reports have shown successful emergency ventilation via tube exchangers using expiratory ventilation assistance after multiple failed intubation attempts (Category B4-B evidence).
- Devices for noninvasive airway management of patients with unanticipated or emergency difficult airways include:
- Rigid laryngoscopic blades of alternative designs and sizes
- Adjuncts (e.g., introducers, bougies, stylets, and alternative tracheal tubes)
- Videolaryngoscopes
- Flexible intubation scopes
- Supraglottic airway devices (supraglottic airways)
- Lighted or optical stylets
- Rigid bronchoscopes
