[How do you intubate the trachea?].

We examined whether there was a difference in the description of the tracheal intubation technique among the Japanese textbooks of anesthesiology. We examined Japanese textbooks of anesthesiology stored in a university medical library. We found a considerable difference in the description concerning the technique of the tracheal intubation. To achieve the better compulsory clinical training, we think it is necessary to make a certain criterion for the tracheal intubation.
