A Comparative study of Macintosh, McCoy and Video laryngoscope for hemodynamic alterations

Abstract

Background and Aims: The different designs of laryngoscope have been developed to reduce the incidence of hemodynamic instability during endotracheal intubation. Primary aim of the study is to compare macintosh laryngoscope with mccoy and Truview EVO2 video laryngoscope in term of hemodynamic changes. Metarials and methods: Study was conducted in ninty patients ,thirty in each group, who require endotrachel intubation for elective surgery undergoing in general anesthesia. Results: Laryngoscopy with Truview EVO2 video laryngoscope and McCoy laryngoscope showed lesser hemodynamic alteration during intubation in comparisons with Macintosh laryngoscope. Conclusion: For orotracheal intubation, Truview EVO2 video laryngoscope provides better hemodynamic stability as compared to MacCoy and Macintosh laryngoscope.
