Comparison of Truview PCD and Trupti blade laryngoscope in adult patients of anticipated difficult Intubation

Abstract

Background: The Truview PCD and Trupti blade provide better view of vocal cords and do not require the proper alignment of the oral, pharyngeal, and laryngeal axes as required with the Macintosh blade. Objective: To compare the laryngeal view and hemodynamic response to laryngoscopy and intubation with Truview PCD and Trupti blade in cases with single or multiple predictors of difficult intubation (PDI). Materials and Methods: Sixty adult patients of both sexes who were scheduled to undergo general anesthesia with endotracheal intubation were divided into two groups. Laryngoscopy was performed with Truview blade in group A and with Trupti blade in group B. Laryngeal view was graded by the Cormack–Lehane classification after laryngoscopy. Hemodynamic response during laryngoscopy and intubation was compared in both the groups. Results: Truview PCD was found to have better Cormack–Lehane glottic view and less hemodynamic response. The time required for the tracheal intubation was higher with Truview PCD blade than that with Trupti blade. Conclusion: The Truview PCD and Trupti blade both are better for intubation in adult patients having less than three PDI.
