Patients will be intubated by an experienced anesthesiologists. Anesthesiologist first uses Macintosh laryngoscope then KingsVision videolaryngoscope and lastly C-MAC videolaryngoscope to intubate patients. Cormack-Lehane scores, the time from the start of laryngoscopy to visualization of the vocal cords and the time from the visualization of the vocals from the successful intubation will be recorded. The success of the intubation will be assessed with bilateral chest auscultation.
