Brief Summary

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

The investigators studied the efficiency of Macintosh laryngoscope and the King Vision video laryngoscope in adult patients scheduled for general anesthesia. Best Cormack-Lehane score obtained, glottic view time, intubation time, time to ventilation, correlation between the Mallampati classification and the Cormack-Lehane grades, and complications related to laryngoscopy and intubation has been investigated.

Detailed Description

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

Securing the airway is essential in general anesthesia. Anesthetic problems related to airway management constitute 17% of closed claims, difficult intubation being the most common one with an occurrence rate of 5%. Problems like delayed intubation, misplaced tracheal tube, or airway trauma are frequently seen in outpatient settings and end up with either death or hypoxic brain damage. Therefore, preoperative visit should include detailed assessment of the airways according to clues of difficult intubation.Several studies compared the King Vision video laryngoscope with other laryngoscopes in manikins simulating difficult airway scenarios, and reported better glottic views. The investigators aimed to study the correlation between the Mallampati classification and the glottic views (Cormack-Lehane grade) obtained with Macintosh laryngoscopy, and the King Vision video laryngoscopy in adult patients scheduled for general anesthesia. Secondary outcomes will be successful intubation rate, time to obtain the best view, time to successful intubation, and complications related to laryngoscopy will be compared.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

Patients scheduled for general anesthesia with endotracheal intubation will be randomized to either intubation with Macintosh laryngoscope first or King Vision videolaryngoscope first. All patients will be intubated with both laryngoscopes.
