title: [Study on correlation between otitis media with effusion and tracheal intubation].
abstract: OBJECTIVE
  To explore the factors related to the occurrence of otitis media with effusion (OME) in patients with long-term tracheal intubation.
  
  
  METHODS
  This retrospective study included 47 cases with endotracheal intubation more than 7 days (endotracheal intubation group) and 20 cases without mechanically ventilated in the same period(control group). The relationships between secretory otitis media with age, gender, intubation method,duration of intubation, breathing patterns, consciousness, gastric tube position were analysed.
  
  
  RESULTS
  The study showed 27 out of 47 patients in endotracheal intubation group had OME, 9 cases had negative pressure in the middle ear and 11 patients were normal. No OME was found in control group, and 2 cases with negative pressure in bilateral middle ear were detected. The incidence of OME was significantly increased in patients with the application of ventilator in PEEP mode or nasotracheal tube, and with conscious disturbance or tracheal intubation using for more than 10 days. The presence of OME had a significantly higher rate in patients with nasal intake subjects than the oral intake subjects. The incidence of OME decreased significantly in patients using glucocorticoid.
  
  
  CONCLUSIONS
  The incidence of OME increased in patients applied with tracheal intubation for more than 7 days. Ventilator in PEEP mode, nasotracheal tube, and conscious disturbance were closely related with OME. Application of glucocorticoids reduced the incidence of OME.
