Methods First, 704 patients receiving CO2 laryngeal laser operation from July 2, 2003 to August 21, 2008 were enrolled, and their risk events and causes were systematically analyzed. Second, in vitro experiment, we tested the tolerance of the PVC tube against different CO2 laser energy in different cutting patterns when the cuff was inflated in water or air. We also tested the combustion conditions of the PVC tube in different oxygen concentration, laser energy and cutting patterns. Results Tracheal cuff were punctured by the laser in 92 of all 704 cases. Spark and dense smoke were observed in 8 and 37 cases respectively.
