Abstract :

Introduction: Though macintosh laryngoscope is a standard for intubation, new laryngoscopes are being introduced to reduce the disadvantages of macintosh. Trueview EVO2 laryngoscope has some advantages over macintosh laryngoscope. Material and Methods: For this randomized, prospective study, 60 patients were allocated to either of the two groups and laryngoscopy and endotracheal intubation done in Group A by macintosh laryngoscope and in Group B by truview EVO2 laryngoscope. The time taken for intubation, number of intubation attempts, POGO score., Cormack–lehane grading, rescue technique for intubation, haemodynamics and side effects were studied Results: POGO score of 100% was seen in maximum number of patients in group B compared to group A. Cormack lehane grade I was seen in maximum number of patients in group B Number of attempts taken were more in group B and statistically significant. Rescue technique like use of bougie, external pressure were used more in group A compared to group B. Mean time for laryngeal intubation was more in group B compared to group A. Haemodynamics were comparable between the groups. Minor complications seen and they were comparable. Conclusion: Truview EV02 laryngoscopy is associated with improved view of glottis , stable hemodynamic parameters, less complications but at the cost of longer intubation time and increase number of attempts compared to Macintosh laryngoscope
