Background And AimsVideo laryngoscopes resemble traditional laryngoscopes, but they have a video chip embedded in the tip of laryngoscope blade. This enables the operator to "look around the corners" which is not possible with conventional direct laryngoscopes. The present study was undertaken to compare Truview video laryngoscope and Macintosh laryngoscope for glottis visualization, ease of tracheal intubation, and associated hemodynamic response.SettingThe study was conducted in operation theater in a medical college.Study DesignIt was a randomized prospective observational study.Materials And MethodsSixty patients of American Society of Anesthesiologists Grade 1 and 2 of either sex aged 18-60 years who were scheduled to undergo elective surgery requiring general anesthesia with orotracheal intubation were selected. In patients of Group T (n = 30), intubation was done using Truview video laryngoscope, while in Group M (n = 30), intubation was done using Macintosh laryngoscope. Various airway and hemodynamic parameters were assessed and compared.Statistical AnalysisStatistical analysis was done using Chi-square test, paired and unpaired Student's t-test, and ANOVA test. P < 0.05 is considered statistically significant.ResultsDistribution of modified Mallampati Class (MMPC), ease of laryngoscopic blade insertion, and size of cuffed endotracheal tube used were statistically comparable in both the groups. The time to intubation was more in Group T (37.16 ± 8.23 s) as compared to Group M (29.80 ± 6.75 s). There was a statistically significant better modified Cormack and Lehane (CL) grading view obtained in Group T as compared to Group M (P = 0.025). CL Grades 2 and 3 were not seen in any of either of the group. The mean intubation difficulty score (IDS) was significantly lower in Group T (0.3 ± 0.60) as compared to Group M (0.73 ± 0.86). In both the Groups T and M, the mean heart rate, systolic blood pressure (BP), and diastolic BP were significantly increased from baseline for up to 3 min after laryngoscopy, but they were comparable between the two groups all the time.ConclusionTruview propaganda cum distribution laryngoscope provides a better glottis view than the Macintosh laryngoscope. Although it requires a longer time to intubate using Truview, the overall IDS score was lower as compared to Macintosh laryngoscope. Hemodynamic changes remained similar in both the groups.Copyright: © 2021 Anesthesia: Essays and Researches.
