Comparison of Truviewscope and C-Mac Video Laryngoscope with the Conventional Macintosh Laryngoscope in Improving the Glottic View during Endotracheal Intubation
Journal Title: International Archives of Integrated Medicine - Year 2018, Vol 5, Issue 12
Abstract
Background: In anesthetic practice, the introduction of multiple novel laryngoscopes has simplified visualization of the vocal cords and has reduced the complications arising due to difficult or failed tracheal intubation. Both Truview scope and C-Mac video laryngoscope have been reported to provide a comparable or superior glottic view on comparison with conventional Macintosh laryngoscope. Materials and methods: A randomized controlled study was conducted in 100 subjects scheduled for elective surgery equally divided into 2 groups. Conventional Macintosh laryngoscopy was done initially in all subjects enrolled for the study. For the Glottic view, One Group (n=50) underwent Truview laryngoscopy while the other (n=50) underwent C-Mac video laryngoscopy. Results: The improvement in glottic view from original MCL (Modified Cormack & Lehane) grading obtained from Macintosh laryngoscope was 40% (n=23) in Truview compared to 46% (n=23) in C-Mac video laryngoscope while downgrading of view was observed in 10% (n=5) in group– T compared to none in C-Mac video laryngoscope. There were no statistically significant difference in Intubation Difficulty Scale (IDS) scores between the groups (P = 0.072). The mean duration of time for endotracheal intubation with C-Mac video laryngoscope (23.10 seconds) was significantly shorter compared with Truview laryngoscope (31.26 seconds). Conclusions: There was an improvement in view of the glottis in both Truview and C-Mac video laryngoscope from the initial Macintosh laryngoscope view. But C-Mac video laryngoscope offered better view improvement and also required a shorter time for intubation compared to Truview laryngoscope.
