Tracheal intubation is the preferred technique to secure the airway and apply mechanical ventilation. However, when performed by untrained medical personnel, tracheal intubation via direct laryngoscopy has a high rate of failure. The GlideScope (Verathon Medical Europe, Ijsselstein, Netherlands) technique improves the success rate for difficult tracheal intubation performed by experienced physicians; whether this technique improves the success rate for normal intubations when performed by inexperienced personnel as well is unknown. Therefore, the authors compared the success rate of direct laryngoscopy versus the GlideScope technique performed by personnel inexperienced in tracheal intubations.Twenty volunteers, who had had only manikin training for tracheal intubation, attempted 5 intubations with either technique in patients scheduled for general anesthesia within a time limit of 120 s.Two hundred patients were divided into 2 groups for intubation via direct laryngoscopy (n = 100) or the GlideScope technique (n = 100). Between groups, there was neither a clinically relevant difference in the anthropometric data nor in the medication used for anesthesia. The overall success rate was 93
