Abstract
We examined the appropriate head position for tracheal intubation using Airway Scope (AWS, HOYA made, Tokyo), a video type laryngoscope. Thirty nurses who have never used AWS conducted a tracheal intubation using the AWS with a mannequin. We set the head of the mannequin to a horizontal position that was substantially horizontal or to an elevated position, that was set about 5 cm higher than horizontal. We compared the time required for intubation (intubation time) in both head positions. Intubation time with the horizontal position was shorter than with the elevated position, suggesting that intubation using AWS is easier when the head position is nearly horizontal.
