Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the clinical performance, quality of larynx visualization and difficulty of videolaryngoscopic intubation in patients with a reduced mouth opening (1.0 to 3.0 cm) utilizing the latest generation of GlideScopeTM Spectrum low profile laryngoscopy system.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Reduced mouth opening in adults has been proven an important risk factor for difficult endotracheal intubation utilizing both direct and indirect laryngoscopy techniques, and a major reason for anesthesia-related adverse events. Over the past two decades, videolaryngoscopy has evolved to be the primary indirect laryngoscopy technique in a difficult endotracheal intubation setting. The possibility for optimal visualization of the laryngeal structures renders this method particularly helpful in patients with limited mouth opening. Especially videolaryngoscopy with acute-angle blades has been proposed to be favorable over conventional direct laryngoscopy in this setting. However, previous research has shown that a mouth opening of approximately 2.0 - 3.0 cm represents an independent risk factor and a possible critical lower limit for safe videolaryngoscopic intubation.

The latest generation of GlideScopeTM Spectrum blades may provide sufficient intubation conditions even in patients with a maximum mouth opening below 3.0 cm.

Our research group aims to evaluate the clinical performance, quality of larynx visualization and severity of videolaryngoscopic intubation the GlideScopeTM Spectrum system in patients with a small mouth opening.
