67 long intubated, critically ill patients were examined by direct laryngoscopy between the 3rd and 14th day of intubation. It was found that even after 5 days most of the patients investigated had severe laryngeal damage. Damage occurs preferentially on the vocal cord (laryngeal granuloma), on the arytenoid vocal process and on the cricoidal plates (ulcerations). It is concluded that laryngoscopy should be performed after 5 days of intubation at the latest to determine the extent of laryngeal damage. If necessary, secondary tracheotomy should be considered.
67例长期插管的危重症患者在插管后第3天至第14天接受了直接喉镜检查。结果发现，即使在5天后，大多数接受检查的患者仍有严重的喉部损伤。损伤主要发生在声带（喉部肉芽肿）、杓状软骨声带突和环状软骨板（溃疡）。结论是，最迟应在插管5天后进行喉镜检查，以确定喉部损伤的程度。如有必要，应考虑行二期气管切开术。
