INTRODUCTION: @entity4671 is an anesthetic agent with rapid onset, short duration of action, a generally stable hemodynamic profile, and cerebroprotective effects. It is used in the hospital setting to facilitate emergency endotracheal intubation. This helicopter EMS used @entity4671 as an intubating agent without paralytics for 2 years. METHODS: Intubations performed by the helicopter crew using @entity4671 alone were reviewed. Intubation was classified as successful or unsuccessful. Successful intubations requiring three or more attempts or repeated doses of @entity4671 were interpreted as difficult. RESULTS: Fifty @entity1 received @entity4671 to facilitate orotracheal intubation. @entity4671 was the sole agent in 44 of these cases. Mean age was 31 years (range 4-79); 35 @entity1 (80%) were @entity1 . Most @entity1 (79%) were victims of blunt @entity130 . The mean dose of @entity4671 was 0.5 mg/kg (range 0.3-1.1). Hemodynamic parameters remained stable. Intubation was successful in 39 @entity1 (89%). Intubation was difficult in seven @entity1 (16%) and unsuccessful in five (11%). @entity7871 was noted in three of the five @entity1 for whom intubation was unsuccessful. Other complications included @entity391 in eight @entity1 and @entity410 -like activity in one @entity1 . CONCLUSION: @entity4671 can be used to facilitate emergency endotracheal intubation in the prehospital air medical setting, with a success rate of 89%. At the doses used in the study, hemodynamic parameters remained stable, but intubation was difficult or unsuccessful in 27% of @entity1 . @entity7871 , which may represent orofacial @entity2045 or inadequate relaxation, is common in @entity1 who cannot be intubated with @entity4671 . @entity4671 is recommended as a sole agent for facilitating intubation only when rapid sequence intubation with @entity912 is contraindicated or otherwise undesirable.
