PURPOSE: We tested our hypothesis that a Parker-tipped tracheal tube could improve the reliability of tracheal tube passage as compared to a Murphy-tipped tracheal tube during Airway Scope-assisted intubation in a manikin. METHODS: Twenty-seven resident doctors performed Airway Scope-assisted intubations using both tracheal tubes, and the number of times the tracheal tube tip touched the glottis or other laryngeal structures was counted on the Airway Scope monitor. RESULTS: The incidence of the tracheal tube tip touching the glottis during Airway Scope-assisted intubation using the Parker-tipped tracheal tube (7.4%; 2 of 27 attempts) was significantly less than that obtained using the Murphy-tipped tracheal tube (33.3%; 9 of 27 attempts; P = 0.039). CONCLUSION: When the advancement of a conventional tracheal tube during Airway Scope-assisted intubation is likely to result in collision with the glottis or other laryngeal structures, the selection of a Parker-tipped tracheal tube is a better option.
