Comparison of Tracheal Intubation Using the Storz's C-Mac D-blade(TM) Video-Laryngoscope Aided by Truflex(TM) Articulating Stylet and the Portex(TM) Intubating Stylet.

Background: Tracheal intubation using Storz's C-Mac D-blade(TM) videolaryngoscope is associated with difficult negotiation of the tracheal tube into the glottis due to steep angulation of its blade.

Objectives: In this study, we hypothesized that Truflex(TM) articulating stylet with its ability to dynamically tailor the ETT shape to patients' oropharyngeal anatomy would be better suited to the D-blade angulation and ease tracheal intubation compared to Portex(TM) intubation stylet.

Patients And Methods: Following approval by the Ethical Issues Committee and informed consent, 218 ASA I and II patients of either sex were enrolled in this interventional, single-blind, randomized controlled trial.

Assessment of Truflex articulating stylet versus conventional rigid Portex stylet as an intubation guide with the D-blade of C-Mac videolaryngoscope during elective tracheal intubation: study protocol for a randomized controlled trial.

Background: A variety of videolaryngoscopes with angulated blade have been recently introduced into clinical practice. They provide an indirect view of the glottic structures in normal and challenging clinical settings. Despite the very good visualization of the laryngeal structures by these devices, the insertion and advancement of the endotracheal tube may be prolonged and occasionally fail as it does not conform to the enhanced angulation of the blade.
