A Clinical Comparison between the Standard Macintosh and the Trupti Laryngoscope Blade for Laryngeal Visualization in Anaesthetised Adults

Year: 2024
Type: article
Abstract: Background: Difficult airway may be encountered in both anticipated and unanticipated circumstances. Difficult laryngoscopy and failed intubation result in severe morbidity related to anaesthesia. This has forced the anaesthesiologists to pursue their interest in developing newer gadgets to facilitate successful and safe endotracheal intubation. One such gadget is the levering laryngoscope blade. We conducted a clinical trial to compare the usefulness of Trupti blade with Standard Macintosh blade for providing glottic view, for endotracheal intubation. Methods: We included 235 patients belonging to ASA I and II, of either Sex, between 18-70 years, undergoing elective surgery and requiring endotracheal intubation. Results: We found that, the incidence of difficult laryngoscopy with Standard Macintosh was 7.66% compared to 0.85% with Trupti blade in Elevated position. Trupti blade in Elevated position significantly improved restricted glottic view when compared with Standard Macintosh blade. However, in Neutral position the Trupti blade provided less grade I and II and more grade III and IV views when compared to Standard Macintosh blade, suggesting worsening of glottic view. Conclusions: The Trupti blade in elevated position significantly improved the glottic views during difficult laryngoscopy in comparison with Standard Macintosh blade. However, in Neutral position Trupti blade did not behave identical to the Standard Macintosh blade and made the glottic view worse. The Trupti blade may be added to the armamentarium of aids to difficult intubation available in the operation theatre as well as in ambulances.
