We have previously described the design for a new self-inflating cuff for use on endotracheal and tracheostomy tubes. The pressure characteristics of this new cuff have been reported. The present report presents our experience with this self-inflating cuff in over 200 laboratory observations demonstrating its effectiveness in preventing tracheal damage. Tracheostomy tubes mounted with self-inflating cuffs were kept in the dogs for six weeks without causing tracheal ulceration. Our clinical experience in 52 patients is also described. Endotracheal, nasotracheal, and tracheostomy tubes were used intraoperatively and for long periods of ventilation. No tracheal damage could be shown at postmortem examination in two patients dying of their disease, 10 and 25 days after continuous ventilation.
我们之前描述了一种用于气管内导管和气管造口术导管的新型自动充气袖带的设计。该新型袖带的压力特性已有报道。本报告介绍了我们在200多次实验室观察中使用这种自动充气袖带的经验，证明了其在预防气管损伤方面的有效性。装有自动充气袖带的气管造口术导管在狗体内留置六周，未引起气管溃疡。我们还描述了对52例患者的临床经验。术中及长时间通气时使用了气管内导管、鼻气管导管和气管造口术导管。在持续通气10天和25天后死于疾病的两名患者的尸检中，未发现气管损伤。
