Background and aims: Glidescope and Airtraq were designed to facilitate intubation and to improve teaching intubation. The investigators want to find their efficacy in normal airway, tongue edema and face-to-face orotracheal intubation models by novice personal.

Material and Methods: After Kocaeli Human Researches Ethics Committee approval, thirty six medical students who were on the beginning of their third year were enrolled in this study. After watching a video about the intubation of one of these devices, they attempted to intubate an adult manikin in three different airway models in a random order; first in normal airway, second, tongue edema and finally, in an entrapped manikin by face-to-face approach with Glidescope or Airtraq. Intubation attempts, insertion and intubation times, success rates, Cormack-Lehane grades, need of maneuvers of these devices were recorded.

Trauma victims mostly had to be intubated at the scene of the area with the paramedics. In a suspect of a cervical trauma, patients must be intubated with the least movement. Videolaryngoscopic techniques had several advantages at this condition. We want to investigate which can be used easily by novice personnel.

Inclusion Criteria:

• medical students at their third year,
• novice personnel

Exclusion Criteria:

• anesthesists,
