Optimization of glottic exposure during intubation of a patient lying supine on the ground

Two methods of endotracheal intubation of patients lying on the ground were compared for ease and speed of intubation and minimization of complications in a crossover study of prehospital oriented emergency physicians, Intubation of a mannequin was attempted by the physicians in either a left lateral decubitus (LLD) position or a kneeling (K) position, followed by the alternate position, The LLD position afforded more rapid intubation, better glottic visualization, and less dental trauma, Eighty-seven percent of physicians completely visualized the glottis in the LLD position, versus 33% of the K position group, Intubation times were 10.5 versus 14.6 seconds in the LLD and K positions, respectively(P <.001), The LLD position is a more effective position (in a mannequin model) than the K position for intubation of patients found lying on the ground, a frequent situation in prehospital care.
