Hazards of a new, clear, unmarked polyvinylchloride tracheal tube designed for use with the Nd-YAG laser.

STUDY OBJECTIVE: To compare a new, clear, unmarked polyvinylchloride (PVC) tracheal tube marketed for use during Neodymium-Yttrium-Aluminum-Garnet (Nd-YAG) laser surgery with a conventional marked PVC tracheal tube. SETTING: Research laboratory of a metropolitan, university-affiliated medical center. DESIGN AND INTERVENTIONS: An Nd-YAG laser set to 70 watts was directed at the tracheal tubes through which 5 L/min of oxygen (O2) flowed. The laser was actuated for 1 minute or until combustion occurred. MEASUREMENTS AND MAIN RESULTS: The conventional marked tracheal tube was unaffected when the laser was directed at an unmarked portion of the tube. Laser impingement onto the marked portions of the tube led to combustion after 2.6 seconds. The clear, unmarked PVC tracheal tube was unaffected by 1 minute of Nd-YAG laser fire. When blood or mucus was applied to this tracheal tube, however, Nd-YAG laser actuation resulted in a fire in less than 6 seconds. CONCLUSIONS: The clear, unmarked Sheridan PVC tracheal tube is not recommended for laser airway surgery.
