[Utility of Bullard intubating laryngoscope with a special stylet in two cases of difficult tracheal intubation].

The Bullard intubating laryngoscope is useful for cases of difficult tracheal intubation, but a skilled hand is needed to manipulate it. In two cases of difficult tracheal intubation, we used a recently improved Bullard intubating laryngoscope to which a special stylet is attached to introduce an endotracheal tube easily into the larynx. The difficulties of tracheal intubation were caused by micrognathia and trismus in one case and by restriction of neck movement and trismus due to ankylosing spondylitis in the other case. Using the Bullard intubating laryngoscope with the special stylet, intubation was done smoothly in both cases. This improved Bullard intubating laryngoscope is recommended for cases of difficult tracheal intubation.
