title: [Diagnostic value of sterility sputum aspirating tube and bronchoalveolar lavage by bronchofibroscope in mechanically ventilated patients with lower respiratory tract infection].
abstract: OBJECTIVE
  To compare the diagnostic value of sterility sputum aspirating tube with bronchoalveolar lavage in mechanically ventilated patients with lower respiratory infection.
  
  
  METHODS
  Sixty-four mechanically ventilated patients with lower respiratory infection were selected to collect respiratory passage secretion to analyze the etiology and to evaluate the diagnostic value by using sterility tube aspirate sputum and bronchoalveolar lavage.
  
  
  RESULTS
  The positive rate of sterility tube aspirate sputum and bronchoalveolar lavage was 71.88% and 78.13%, respectively, with no statistical difference between the 2 groups (P>0.05). The consistency rate was 81.25% for the 2 methods.
  
  
  CONCLUSIONS
  Sterility sputum aspirating tube can not only acquire accurate pathogen, provide evidence to select sensitive antibiotics in clinical practice, but also is a simple practice, safe and economical method for patients with lower respiratory tract infection and mechanical ventilation.
