title: Problematic intubation in soldiers: are there predisposing factors?
abstract: Attempts by a combat medical officer to secure the airway of a multiple-injury patient in the field may frequently end in failure. The recurrence of such failures, despite Advanced Trauma Life Support training, is perplexing; therefore, we studied the prevalence of clinical criteria that could predispose active soldiers to difficult intubation. Such known anatomical features and the Mallampati classification were assessed by experts in 250 soldiers at a military outpatient clinic of the Israel Defense Forces. It was found that most soldiers had normal airways. Limitations of head and neck movement, or in opening the mouth, were not observed. Other risk factors were noted in only a small percentage of the study population. Mallampati classes I and II were noted in 40% and 31%, respectively. No statistically significant differences between young (18-21 years) and older (40-44 years) soldiers were found. It was concluded that difficult intubations among soldiers are unlikely to be associated with anatomical causes. Complicated scenarios and deficient skills of the physicians are the most important factors that contribute to in-field failures to secure airway control. Several recommendations to remedy this situation are offered.
