<abstract xmlns="http://www.w3.org/1999/xhtml">Study objective. Videolaryngoscopes can be fitted either with channeled or non-channeled blades, which may result in a different performance and success of tracheal intubation. We investigated the characteristics of the two different blade types of the commercially available KingVisionTMvideolaryngoscope. Design. A prospective, randomized, single center investigation study in a urological operation unit of a tertiary hospital. Subjects and Methods. Forty adult patients undergoing elective urological surgery in general anaesthesia with tracheal intubation were randomly allocated into group 1 (channeled videolaryngoscopy, n = 20) and group 2 (non-channeled videolaryngoscopy, n = 20). We measured the times from laryngoscope insertion to recognize the glottis and to conclude tracheal intubation. The number of laryngoscopy/intubation attempts and the degree of visual glottis exposure on a visual analog scale from 0 (glottis not visible) to 10 (glottis fully visible) was assessed. The lowest SpO2value during airway management was recorded. Results. There was no statistically significant difference in biometric data between the 2 groups. The time from the laryngoscope insertion to glottis recognition with the non-channeled blades was 5 (4-8) s as compared to the channeled ones with 11 (7-14) s (median and range; p = 0.01). Intubation duration was shorter with the channeled blades 17 (12-27) s vs. 29 (25-51) s (median and range; p &lt; 0.001). Number of laryngoscopy/intubation attempts, grades for glottis visibility, intubation difficulty were not different. The lowest SpO2was 98% in both groups. Conclusions. Videolaryngoscopic glottis recognition time was longer and the total time to secure the airway was shorter with the channeled blades.</abstract>
