The Impact of Location and Asset Type on the Success of Advanced Airway Management in a Critical Care Transport Environment.

Objective: Advanced airway management (AAM) is a critical component of prehospital critical care. Airway management in flight can be more challenging because of spatial, ergonomic, and environmental factors. This study examines the frequency of in-flight intubation (IFI), first-pass success (FPS) rates, and definitive airway sans hypoxia/hypotension on first attempt (DASH-1A) across different locations of airway management.

Methods: We conducted a retrospective database analysis of all patients transported between January 2016 and July 2021 who received AAM from a single air medical service. Patient records were reviewed for location of intubation, patient characteristics, and FPS and DASH-1A rates. The primary outcome was the frequency of IFI. The secondary outcomes included FPS and DASH-1A rates by location and type of transport asset.

Results: During the study period, 473 patients required AAM. Three percent (15/473) of patients were intubated in an in-flight setting, 28% (130/473) were intubated on scene, and 70% (328/473) were intubated in a health care facility. The primary reason for IFI was unanticipated cardiac arrest or clinical deterioration. The overall FPS rate was 69% (328/473), and the DASH-1A rate was 49% (194/399). Based on the location of AAM, the FPS and DASH-1A rates were the lowest for on-scene intubations (56% [74/130] and 27% [20/74], respectively). Most of the on-scene AAM took place with rotor wing flight crews.

Conclusion: Airway management occurs infrequently in an in-flight setting and is necessary because of patient deterioration or cardiac arrest. Based on our results, we identified opportunities for targeted AAM quality improvement and clinical governance.
