[Late laryngeal and tracheal complications after prolonged naso-tracheal intubation (author's transl)].

The causes, incidence and means of preventing sequelae (late complications) after long-term intubation are discussed and the literature is reviewed. 6 of 353 surviving patients with neurosurgical disorders required treatment following prolonged intubation. The incidence of subglottic and tracheal stenoses was 1,14 per cent and of other laryngeal damages was 1,13 per cent. The primary disorder and unfavourable conditions attending its treatment appear to be responsible for the complications.
