AbstractIn an effort to design a fireproof and reliable method of ventilation during CO2 laser laryngoscopies, a new Venturi jet endotracheal tube coupler has been designed. This allows microdirect laryngoscopy. Its design features are described. Sixteen clinical cases of various laryngeal pathologies treated with direct laryngoscopy and laser excision are ventilated using this system. The clinical data and experiences are discussed. The arterial blood gases done at 20 minutes after muscular paralysis showed a median value of pH 7.45/PO2 252/PCO2 36. No complications or adverse effects were noted. The Venturi jet endotracheal tube coupler allows for jet ventilation through a metal endotracheal tube with reliable ventilation. This is an alternate, reliable, and fire-safe method during laser use.
