Prototype airway management system for use during laser surgery

A Norton metal endotracheal tube with a Merav parachute cuff cemented to the distal end has solved many of the problems involved in administration of anesthesia for laser surgery of the upper aerodigestive tract. The tube is fireproof and provides an air-tight seal for positive pressure ventilation without the impediment of a cuff channel. It is ideal for laser surgery of the oral cavity and pharynx and may be used effectively for glottic lesions in many instances.
