Abstract:
Objective To analyze the constitute of the pathogens of pneumonia in patients by mechanical ventialtion and the results of drugresistane.
Methods The pathogens and the drug sensitivity of 64 cases with v entilator-associated-pneumonia in 86 cases in ICU were detected.
Results 84 strains pathogens were isolated by bacterial culture, the ratio of the gram-negative bacteria to total bacteria isoalted was 69.05%(58 strains), and the gram-posit ive bacteria was 19.05%(16 strains), the fungi was 11.90%(9 strains).P.aerug inose(29 strains), P.klebsiella(14 strain), moniliasis(10 strains)and S.aureus(10 strains)were the four common kinds of pathogens, the multi-drug-resistance on antibiotics was serious.
Conclusion Gram-negative bacteria were the more common pathogens of pneumonia isolated from patients with mechanical ventilation in ICU, the pathogens were multi-drug-resistance to antibiotics, and reasonable using antibiotics were extremely important.
