title: Proximal large-bore jet ventilation for laryngeal laser surgery.
abstract: The carbon dioxide surgical laser has made many open upper airway operations obsolete. However, new laser-related hazards have been encountered, the most serious of which is fire in the airway. Venturi jet ventilation removes that risk and provides an unobstructed surgical field. Indications and techniques for the use of jet ventilation with carbon dioxide laser surgery remain controversial, particularly whether jet ventilation should be used in papillomatosis or in the severely obstructed airway, and whether proximal and distal catheter techniques are equally safe and effective. We report the successful use of proximal large-bore Venturi jet ventilation in 327 consecutive patients undergoing microlaryngeal laser surgery. The technique is ideal for pediatric patients with subglottic stenosis or recurrent respiratory papillomas and has not caused distal seeding in the latter group. We recommend the use of low-pressure ventilation, even in relatively obstructed airways. The experimental evidence reported here corroborates the clinical viewpoint expressed; the technique is safe, simple, and uncomplicated if used with care.
