Then tracheal intubation will be performed. In "group B" size 1 Wis-Hipple blade will be used for direct laryngoscopy in the same manner. In "group C" a size 1 C-MAC straight blade for indirect videolaryngoscopy will be used. The blade will also be placed under the epiglottis and a photo of the direct view with the C-MAC will be taken. In group C the second anesthesiologist will save the images of best glottic view on a SD card in the C-MAC monitor.
