Clinical Trial Summary

C-MAC videolaryngoscope (Karl Storz, Tuttlingen, GERMANY) with its Macintosh like blade is used with standard direct laryngoscopy technique. KingsVisionTM videolaryngoscopes (KingSystems, IN, USA) have also Macintosh like single use blades that are channeled, wider and shorter than conventional Macintosh blades.We aim to compare these two laryngoscopes and Macintosh laryngoscope during routine intubation in adult patients.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cormack-Lehane Score	Patients will be preoxygenated with 100% oxygen for 3 minutes before the anesthesia induction. After induction when the train of four ratio reaches %0, patients will be intubated by one of three anesthesiologists with at least 10 years of experience. The anesthesiologist first will use the Macintosh laryngoscope then KingsVisionTM videolaryngoscope and lastly C-MAC videolaryngoscope to intubate the patients. The Cormack-Lehane scores observed during each laryngoscopy will be recorded	5 minutes	No
Secondary	time	Patients will be preoxygenated with 100% oxygen for 3 minutes before the anesthesia induction. After induction when the train of four ratio reaches %0, patients will be intubated by one of three anesthesiologists with at least 10 years of experience. The anesthesiologist first will use the Macintosh laryngoscope then KingsVisionTM videolaryngoscope and lastly C-MAC videolaryngoscope to intubate the patients. The time from the start of laryngoscopy to the visualization of the vocal cords and the time from the visualization of the vocals from the successful intubation observed during each laryngoscopy will be recorded.	5 minutes	No
