Videolaryngoscopic Difficult ıntubation and Glottic View Score: A Multicentre Prospective Study

Starting soon

Conditions studied: Airway Management

In brief

Background: Videolaryngoscopy has improved glottic visualization and facilitated tracheal intubation. However, difficulties-including failed intubation-still occur. At present, no prospectively derived classification system exists to assess the difficulty of videolaryngoscopic (VL) intubation across both normal and anticipated difficult airways. Additionally, current glottic view grading systems, designed for direct laryngoscopy, may not adequately capture the specific challenges of VL intubation. Objectives: This study aims to: 1. Develop a predictive model for difficult VL intubation in surgical patients with both normal and anticipated difficult airways. 2. Create a glottic view scoring system specifically tailored to videolaryngoscopy. 3. Compare the predictive accuracy of the new scoring system with existing laryngeal view grades in forecasting difficult VL intubation.
