Brief summary

The investigators suppose that direct laryngoscopy is connected with deeper insertion of endotracheal tube in comparison to videolaryngoscopy. Correction of this malposition can cause postoperative discomfort and further complications in some patients.Routine use of videolaryngoscopy could minimize these problems.

Detailed description

100 patients scheduled for elective neurosurgical procedures will be randomized into two groups. Patients in group A will be intubated by videolaryngoscopy (GlideScope), patients in group B by direct laryngoscopy, in both groups will be rigid stylet used. Intubation will be done under propofol anesthesia, targeted entropy 40 to 50, and deep relaxation (neuromuscular transmission target level 0). Sufentanil will be used to block tracheal reflexes. In both groups the depth of insertion of tracheal tube will be measured in the mouth corner immediately after intubation. Next day, the unpleasant sensations and complications will be recorded (sore throat, stridor, hoarseness, cough and nausea and vomiting) during control visit of patients.
