title: [The role of tracheotomy in saving the patients suffered from lung blast injury].
abstract: OBJECTIVE
  To explore the role of tracheotomy in saving the patients suffered from lung blast injury.
  
  
  METHODS
  To analyse the pathological change of lung blast injury and to make a retrospective analysis for clinical data of 8 cases.
  
  
  RESULTS
  Three severe injuries accompanying asphyxia, SaO2 < 75%, were tracheotomized and sucked hemorrhagic frothy sputum in trachea at once, and they were saved successfully. The other 5 cases, SaO2 > or = 90%, were not tracheotomized.
  
  
  CONCLUSIONS
  During saving the lung blast injury, tracheotomy has an important role in sucking hemorrhagic frothy sputum in trachea and keeping the respiratory tract unobstructed.
