Abstract :

Background & Aim: Prolonged laryngoscopy is associated with haemodynamic pertubances and can increase morbidity in high-risk patients. Many videolaryngoscopes are now available to the anaesthesiologist. This randomised controlled trial was undertaken to evaluate and compare two chanelled videolaryngoscpes, Airtraq (AQ) and KingVision(KV). Material & Methods: 60 consecutive ASA physical status I - III patients, who were to undergo surgery requiring general anaesthesia & endotracheal intubation were enrolled & randomly assigned into Airtraq (AQ) & KingVision (KV) groups. Each group had 30 patients. Changes in haemodynamic variables at various intervals were recorded as the primary outcome. Other parameters such as time to view glottic opening, time to intubation, number of attempts to intubate, glottic views, requirement of external manuvers and adverse events were recorded. Results were compared among the study groups with the help of Fisher test, Student �t� test, Mann Whitney U test and Chi-Square test. Result: The heart rate, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) values were comparable between both the groups for the time intervals recorded. There was no difference statistically in the adverse outcomes during laryngoscopy. Parameters like percentage of glottic opening (POGO) score and intubation difficulty score (IDS) were also similar. P <0.05 was considered statistically significant. Conclusion: Both the video laryngoscopes, KingVision and Airtraq, were found to be comparable with each other in all respects as specified in this study. Personal preference of the clinician managing the airway and cost considerations could govern the choice between the two video laryngoscopes that were evaluated in this study.
