A CLINICAL STUDY COMPARING TRACHEAL INTUBATION USING TWO DIFFERENT BLADES OF KING VISION VIDEO LARYNGOSCOPE: CHANNELED VS. NONCHANNELED

Abstract

Background: Video-laryngoscopes are the latest portable devices for indirect laryngoscopy, routine and difficult endoscopy with cutting-edge technology facilitating easy visualization, easy handling and high success rate of intubation in both routine and difficult endotracheal intubations. The primary study objective was to determine whether there is a difference in total intubation time (seconds) for the King’s Vision Video Laryngoscope (KVVL) non-channeled compared to the channeled blade. Secondary outcomes were: first attempt and overall intubation success rates, visualization of the glottis using Cormack & Lehane grade and percentage of glottic opening score in (POGO). Methods: This study is a prospective randomized study comprising of 66 patients undergoing surgery under general anesthesia divided into two groups of n=33 each; Group C intubated using KVVL channeled blade and Group NC intubated using KVVL non -channeled blade. The difference in the Cormack and Lehane grading of both the groups was statistical insignificant (p value >0.367).
