The Pentax AWS-s200 (Hoya, Japan : s-200) is a new videolaryngoscope. Its weight is 190 g, and it is lighter than the original AWS (AWS-s100L: s-100). It has a USB port, and its screen is wider and clearer than the s-100. ⋯ We used the s-200 in 20 patients, and could see a full view of the glottis, and tracheal intubation was successful in all patients. But tracheal intubation was not smooth in 10 of 20 patients, mainly because the tube impacted the right arytenoid. We felt the target mark of the s-200 may be incorrectly positioned.
