The search for an ideal endotracheal tube to prevent the possibility of a catastrophic airway disaster associated with laser surgery may be closer to an end with recent advancements in equipment. Mitchel B. Sosis, MD, PhD, and David D. Caldarell, MD, Chicago, Ill, presented their findings at the annual meeting of the American Academy of Otolaryngology—Head and Neck Surgery held in Kansas City, Mo, in September 1991. Drs Sosis and Caldarell evaluated the new endotracheal tube by Fuji Systems. This new silicone endotracheal tube contains ceramic particles that offer theoretical advantages over other tubes. The presenters compared this tube with the Mallinckrodt polyvinyl chloride endotracheal tube with and without copper-foil protection. Each endotracheal tube had 5 L/min of oxygen flowing through it and was tested with carbon dioxide and neodymium: yttrium aluminum garnet lasers at standard power setting and standard distance. Each tube was exposed to the carbon dioxide laser
