Chondronecrosis of the cricoid cartilage after intubation. Two case reports.

Chondronecrosis of the cricoid cartilage is a rare complication of intubation. The records of two children were reviewed. An 8-month-old girl with myelomonocytic leukaemia developed chondronecrosis 10 days after a 2-day period of ventilation. A 4-year-old girl comatose after poisoning by the histamine antagonist, alimemazine, developed chondronecrosis after a 2-day period of intubation. The complication was suspected when extubation led to dyspnoea owing to laryngeal stridor and was confirmed by direct laryngoscopy. We review the development of the condition, the causative factors, treatment and prevention.

Laryngotracheal stenosis in children after intubation. Report of five cases.

Acquired laryngotracheal stenosis is a serious long term complication of tracheal intubation with an incidence of 0.7 to 8% in intubated children. We report five cases of subglottic stenosis over a 4.5-year period and review the pathology and pathogenesis of the condition. A diagnosis of subglottic stenosis was suspected when extubation failed due to the onset of dyspnoea or laryngeal stridor. An incidence of 0.9% of all intubated children was observed. We conclude that the main components contributing to stenosis are pathologies with decreased mucosal capillary perfusion pressure and intubation conditions.

[Iatrogenic laryngotracheal stenosis. A follow-up of 20 recent cases].

The aim of this study was to analyse the follow-up of patients with a history of endotracheal intubation and/or tracheotomy because of respiratory distress, surgical necessity or long-term resuscitation. Twenty adults were followed up in a ENT facility for laryngeal or tracheal stenosis, of which 7 cases were diagnosed during 1994. This study shows that, in patients with a history of intubation, or intubation followed by tracheotomy, the stenosis developed within two months after resuscitation with a favourable outcome. After tracheotomy only, the stenosis developed later (2 months or more) with more recurrences. The diagnosis of stenosis was made on gradual or acute dyspnea. While respiratory resuscitation methods are essential and often life-saving, they are not without complications. Laryngeal and tracheal stenosis could be largely prevented by more careful techniques of endotracheal intubation and tracheotomy. Periodic endoscopic airway surveillance is useful to detect stenosis even when there is no clinical symptom.
