The application of bronchoalveolar lavage by bronchoscope in aetiology diagnosis of pulmonary infection after surgical operation

Objective To observe the applied effects of bronchoalveolar lavage（BAL） by bronchoscope in aetiology diagnosis of pulmonary infection after surgical operation.Methods Bronchoscope examination and BAL was performed in 96 patients with pulmonary infection after surgical operation.BAL fluids were sampled for pathogenic study.Results Among 96 patients,104 effective aetiology diagnostic cases were acquired.187 strains of bacteria were separated out of all the bacterial organisms.Gram-positive bacteria,Gram-negative bacteria and fungi accounted for 52 strains（27.8%）,126 strains（67.4%）,9 strains（4.8%） respectively.45 cases（43.3%） were infected with single bacterium,59 cases（56.7%） were infected with two or more bacteria.Then adjust therapy according to the result of susceptibility test,87 patients were cured,9 patients were improved.Conclusion BAL by bronchoscope can be applied generally to aetiology diagnosis of pulmonary infection after surgical operation,and provides effective clinical treatment foundation.
