Clinical Trial Summary

The primary goal of this study was to identify parameters affecting the failure of videolaryngoscopy in clinical practice; secondly, the incidence of videolaryngoscopy use and the most frequently used patient groups.

Description:

Videolaryngoscopy is widely used in the management of patients with presumed difficult airway. It offers an improved laryngeal view compared with direct laryngoscopy and increases the likelihood of successful intubation in patients for whom direct laryngoscopy is anticipated to be difficult. It is among the most frequently preferred difficult airway devices due to its ease of use, portability and direct laryngoscopy resemblance. The use of videolaryngoscopy has been shown to improve intubation success in many cases associated with difficult intubation, such as morbid obesity, pregnancy, limitation of cervical motility, and poor mouth opening.
