Abstract:
We studied the efficacy of the Pentax-AWS (Tokyo, Japan), a new portable, battery-operated video-laryngoscope, in 100 patients. It was possible to insert the blade of the Pentax-AWS and to see a full view of the glottis on the first attempt in 99 of 100 patients. In the remaining patient, insertion of the Pentax-AWS was abandoned because of a risk of damaging teeth that were already loose. Tracheal intubation was successful in 98 patients. The median time taken for tracheal intubation was 35 s (range, 5-120 s).
