title: Role of infection in the development of acquired subglottic stenosis in neonates with prolonged intubation.
abstract: OBJECTIVE
  To examine whether clinically diagnosed infection correlates with subsequent development of subglottic stenosis in intubated neonates.
  
  
  METHODS
  Sixty-two neonatal infants intubated for more than 14 days were examined. Several risk factors for subglottic stenosis, including infection, duration of intubation, frequency of intubation, the size of the endotracheal tube etc., were evaluated by multiple logistic regression analysis.
  
  
  RESULTS
  Infection that occurred within 14 days of intubation showed a positive correlation with subsequent subglottic stenosis. The duration of intubation, frequency of intubation and the size of the endotracheal tube did not affect the development of subglottic stenosis. The majority of infections were considered to be respiratory tract infections, including pneumonia.
  
  
  CONCLUSIONS
  Infection occurring within 14 days of intubation is considered to be a risk factor for acquired subglottic stenosis in neonates intubated for more than 14 days. Prevention of infection within 14 days of intubation may reduce the incidence of subglottic stenosis in neonates.
