Randomized Controlled Trial Comparative StudyMcGrath MAC Videolaryngoscope Versus Optiscope Video Stylet for Tracheal Intubation in Patients With Manual Inline Cervical Stabilization: A Randomized Trial.
Manual inline stabilization of the head and neck is a recommended maneuver for tracheal intubation in patients with a suspected cervical injury. However, because applying this maneuver inevitably restricts neck flexion and head extension, indirect intubating devices such as a videolaryngoscope or a video stylet could be required for successful tracheal intubation. In this study, we compared the clinical performance of the McGrath MAC videolaryngoscope versus the Optiscope video stylet in patients with manual inline cervical stabilization during tracheal intubation. ⋯ The McGrath MAC videolaryngoscope showed a higher first-attempt success rate for tracheal intubation and a shorter intubation time than the Optiscope video stylet in cervical spine patients with manual inline stabilization during tracheal intubation. These results suggest that the McGrath MAC videolaryngoscope may be a better option for tracheal intubation in such patients.

Awake endotracheal intubation is the technique of choice to secure the airway when both mask ventilation and intubation are anticipated to be difficult. We present a case of a patient with a known difficult airway, bronchopleural fistula (BPF), and acute respiratory distress syndrome (ARDS) who was intubated with a double-lumen endotracheal tube (DL ETT) under awake condition using a videolaryngoscope. ⋯ The patient was treated successfully for ARDS and discharged home. To our knowledge, this is the first reported case of successful videolaryngoscope-assisted DL ETT intubation in an awake patient.

Randomized Controlled Trial
A randomized trial of the glottic views with the classic Miller, Wis-Hipple and C-MAC (videolaryngoscope and direct views) straight size 1 blades in young children.
The Miller and Wis-Hipple size 1 blades are widely used for laryngoscopy in children and the C-MAC straight blade is used increasingly in young children, although the glottic views with these blades have not been compared. To determine whether the glottic views with these blades are equivalent. ⋯ The four blades/glottic views were equivalent, although a post hoc analysis demonstrated that the glottic view with the C-MAC videolaryngoscope was superior overall and the view with the Miller size 1 was superior to that with the direct C-MAC view.

Comparative Study
Comparison of direct laryngoscope and McGrath videolaryngoscope in terms of glottic view and hemodynamics in bariatric surgery
In the recent years, videolaryngoscopes (VL) have emerged as alternative devices to direct laryngoscopes (DL) in difficult intubation situations. Therefore, we aimed to compare the Macintosh DL and McGrath VL in terms of the glottic image quality, intubation success, intubation time, hemodynamic response after intubation, and complications in bariatric surgery patients. ⋯ Although we measured longer intubation times with the McGrath VL compared with the Macintosh DL, we obtained a better glottic image without causing hemodynamic changes. However, these findings did not make any difference in terms of intubation success.
