Although tracheal tube cuffs are well known to injure the trachea, attempts to design safer cuff systems have been only partially successful. In 14 dogs, we compared three models of high residual volume, low pressure cuffs, which are considered to be among the safest. Two were air-filled cuffs -- a maintained pressure cuff and a balloon reservoir cuff -- and the third was foam-filled. Tracheal dilatation was considerably more severe with mechanical ventilation than with spontaneous breathing, but the foam cuff produced significantly less dilatation (P less than .005) than the air-filled cuffs.

Complications to tracheostomy and long-term intubation: a follow-up study.
Hospital records of 79 patients treated with tracheostomy or long-term intubation from 1969 to 1971 were reviewed, and the 43 surviving patients were examined by laryngoscopy, x-ray and spirometry for complications subsequent to these treatments. Early complications included one tube occlusion and one case of postextubation stridor in each group, one dislocated tube, one bilateral pneumothorax, and one case of fatal innominate arterial hemorrhage in the tracheostomy group, and two cases of atelectasis in the long-term intubation group. ⋯ Late complications in surviving patients were prolonged hoarseness in six patients treated with prolonged intubation, two of whom had also had tracheostomy. Radiologically verified tracheal stenosis (40-60%), four at the stoma level and one at the cuff level, all occurred in the tracheostomy group.
