Contribution of air medical personnel to the airway management of injured patients.
BACKGROUND
Air medical services are being pressured to demonstrate their value. Airway management is the first priority of care when treating injured patients in the prehospital setting. Injured patients with decreased Glasgow Coma Scale (GCS) are candidates for advanced airway procedures and air medical transport.


OBJECTIVE
The purpose of this study was to determine the extent of air medical crews' contributions to the airway management of the injured patient in the prehospital setting.


METHODS
A study of adult (age > 12 years) injured patients encountered in a field setting, whose GCS on the arrival of the air medical crew was < or = 8, was conducted for 21 months (Feb. 1, 1991-Oct. 31, 1992).


RESULTS
During the study period, 174 patients who met the criteria were transported by the air medical crew. All but one received advanced airways including oral tracheal intubation, nasal tracheal intubation or cricothyrotomy. Of those, 68 (39%) of these procedures were completed by ground personnel (ground group), and 105 (61%) were completed by the air medical personnel (air group). The mean GCS for the ground group was 3.69 and for the air group was 4.69. The distributions were significantly different (Wilcoxon Rank Test p = 0.0002). Nineteen percent (13/68) of the patients whose airways were successfully managed by the ground personnel had a GCS of 5 to 8, as did 44% (46/105) of the air group's patients. The groups' patients were not significantly different in age or sex distribution.


CONCLUSIONS
Properly trained air medical personnel positively contribute to the prehospital care of injured patients by establishing definitive airways in patients with higher GCSs.
