Abstract At the recent meeting of the American Laryngological Association in San Francisco, Calif, two prospective studies comparing a new prototype endotracheal tube to the standard endotracheal tube were reported by Drs Ernest A. Weymuller, Jr, Perry Santos, and colleagues, University of Washington, Seattle. The prototype endotracheal tube consisted of a foam-filled cuff around the endotracheal tube (Bivona) at the level of the true vocal cords. They reported that prior studies in the canine showed less mucosal injury and, based on this, designed two prospective studies. In the first study, assessment of postintubation problems in patients intubated orally for greater than 3 days was carried out. Forty-two patients were evaluated for age, size of endotracheal tube, major diagnosis, duration of intubation, number of reintubations, peak inspiratory pressures, cuff pressures, serum albumin level, Glasgow Coma Score, and Injury Severity Score. These variables were compared with postintubation sequelae, including hoarseness, loss of voice
